Phasix Breast Mesh Lawsuit [2026 Investigation]

What Is Phasix Mesh?

Phasix Mesh is a fully resorbable synthetic surgical mesh made from poly-4-hydroxybutyrate, or P4HB.

BD describes it as a monofilament, macroporous mesh intended to provide general soft tissue support where weakness exists in plastic and reconstructive surgery or in procedures involving soft tissue repair, such as hernia or other fascial defects.

Its open-pore structure is designed to support tissue ingrowth and vascularization during healing.

Unlike a permanent implant, Phasix is intended to provide temporary support and then gradually degrade over approximately 12 to 18 months.

As the material resorbs, the mesh is replaced by the patient’s own tissue.

Is Phasix FDA-Cleared for Breast Reconstruction?

Phasix Mesh is not FDA-cleared or approved for breast reconstruction.

BD’s Instructions for Use describe it as a resorbable implant used to reinforce soft tissue where weakness exists in plastic and reconstructive surgery, or in procedures involving soft tissue repair such as hernia or other fascial defects, and do not identify breast reconstruction as a specific indication.

The IFU also describes the device as a P4HB mesh intended to provide temporary support during healing before gradually resorbing over about 12 to 18 months.

FDA materials state that no surgical mesh has been cleared or approved for use with breast implants or in breast reconstruction, and that the safety and effectiveness of surgical mesh in breast surgery have not been determined.

FDA also issued a 2021 safety communication warning that certain ADM products used in implant-based breast reconstruction showed differing complication rates.

Use of mesh in breast reconstruction and FDA clearance for that use are not the same.

How Has Phasix Mesh Been Used in Breast Reconstruction?

Phasix Mesh has been used in breast reconstruction, including implant-based procedures performed after mastectomy.

Surgical literature discussing P4HB scaffold use describes it as a reinforcement material in breast reconstruction and other breast procedures, even though FDA states that no surgical mesh has been cleared or approved for use with breast implants or in breast reconstruction.

Published breast-reconstruction literature describes Phasix as an internal support structure used by plastic surgeons to support breast implants and reinforce surrounding tissue during healing.

Those reports describe the material as part of implant-based reconstruction techniques intended to provide support during healing and help maintain breast shape or implant position.

FDA records also document reported off-label breast use.

One MAUDE adverse-event report states that P4HB-based Phasix had been used off-label for breast reconstruction in women after mastectomy.

FDA records and published literature show that Phasix has been used in breast reconstruction in actual surgical practice.

What Complications Have Been Associated With Surgical Mesh Used in Breast Surgery?

Women have reported serious injuries after internal mesh surgeries, including infection, migration, disintegration, erosion, and mesh rupture.

Though, complications reported in breast surgeries involving mesh vary based on placement, surgical method, and patient factors.

These complications have been described across implant-based reconstruction and related procedures, including cases where mesh is placed to support implants or reinforce soft tissue.

Acellular dermal matrix products like AlloMax have been linked to higher complication rates in breast reconstruction, prompting FDA warnings.

The type and severity of complications can differ based on how the material is positioned and how the body responds during healing, and may include the complications below.

Infection and Seroma Formation

Complications such as infection, migration, scarring, and pain are commonly reported by women who received internal bra mesh implants.

Infections may develop when bacteria affect the implant pocket or mesh surface, sometimes leading to a chronic abscess, while fluid buildup may require drainage or further procedures and may present as:

• Infection and inflammatory reactions
• Seroma or fluid buildup
• Severe breast pain
• Wound breakdown and delayed healing
• Mesh migration or displacement
• Exposed mesh or tissue erosion
• Skin necrosis and surrounding tissue damage
• Implant failure or loss
• Need for revision surgery or mesh removal

Hematoma and Wound Healing Complications

In some cases, bleeding within the surgical area leads to hematoma and postoperative bleeding are recognized complications following breast surgeries that involve mesh devices, which can interfere with healing and increase the risk of further complications.

Where healing is impaired, delayed wound healing and tissue necrosis are significant complications in breast surgeries that incorporate mesh devices, particularly when blood supply to the tissue is limited.

Implant Malposition/Migration

Mesh migration and displacement refer to situations where the breast mesh or scaffold shifts from its intended position, potentially altering breast shape and undermining the support framework.

When the mesh or implant moves, it can disrupt the intended positioning of the breast, leading to asymmetry, distortion, or implant malposition.

This may occur due to inadequate fixation, tissue weakness, or failure of the mesh to properly integrate with surrounding tissue.

In more advanced cases, displacement can contribute to structural instability and may require revision surgery to reposition or remove the mesh and restore proper support.

Revision surgeries are common when breast mesh or internal bra materials fail to integrate properly, cause ongoing pain, or contribute to structural changes in the breast over time.

Capsular Contracture and Tissue Response

Changes in the tissue surrounding the implant may develop.

Capsular contracture occurs when scar tissue around a breast implant tightens and hardens, which can cause firmness, distortion, and severe breast pain, and may require additional procedures.

Mesh Exposure and Implant Loss

Mesh extrusion and tissue erosion describe situations where the mesh or underlying implant becomes exposed through the overlying skin or incision, often after a period of delayed healing or skin thinning.

In more severe cases, reconstruction failure and implant loss occur when postoperative complications become severe enough that the breast implant and often the mesh must be removed entirely.

Deformity and Revision Procedures

Additional changes may affect the appearance and structure of the breast.

Deformities of the breast, such as rippling, contour irregularities, implant malposition, and visible asymmetry, are documented complications, and revision surgeries are common when breast mesh or internal bra materials fail to integrate properly, causing ongoing symptoms or structural changes.

Chronic Pain and Nerve Issues

Persistent pain after breast surgery, including mesh-supported procedures, has been documented in multiple studies, affecting a significant portion of reconstruction patients even years after their operations.

This pain may develop due to nerve irritation, compression, or damage during implant placement or mesh fixation.

Scar tissue formation and chronic inflammation around the mesh or implant can also contribute to ongoing discomfort.

Patients often report burning, sharp, or radiating pain that does not resolve with standard healing timelines.

In some cases, the pain becomes chronic and may require medical management or surgical revision.

These complications have also been reported in procedures described as internal bra surgery, including internal bra complications and internal bra mesh complications, with outcomes varying based on placement, surgical technique, and tissue condition.

Treatment Options for Breast Mesh Complications

Treatment depends on the type of complication, its severity, and whether the reconstruction can be preserved.

For early or less severe issues, treatment may begin with oral or intravenous antibiotics, particularly where there is cellulitis, pocket infection, or inflammatory response.

Seromas are commonly managed with needle aspiration or ultrasound-guided drainage to reduce fluid accumulation and prevent infection.

Limited wound breakdown or superficial tissue injury may be addressed with local wound care and close surgical monitoring.

In more advanced cases, complications can lead to additional surgeries, including mesh excision, implant removal, and staged reconstruction.

If infection does not respond to antibiotics, surgeons may perform an operative washout of the implant pocket.

Where infection persists, or where there is mesh exposure, tissue necrosis, or structural failure, removal of the mesh and implant may be required.

In these cases, debridement is often performed to remove nonviable tissue and reduce bacterial contamination.

Patients who develop capsular contracture may require capsulectomy, which involves removal of the scar tissue capsule surrounding the implant.

Where implant position or support has failed, pocket revision or a plane change may be considered.

Treatment is often not a single procedure. Some patients require multiple surgeries and delayed reconstruction depending on how the complication progresses.

Breast Mesh Lawsuits and Legal Claims

Breast mesh lawsuits examine whether manufacturers adequately tested, labeled, and disclosed the risks associated with surgical mesh used in breast reconstruction and internal bra procedures.

Many of these products were originally designed to support soft tissue in other anatomical areas but have been used to support breast tissue in implant-based reconstruction.

This includes both synthetic materials and biologic meshes derived from animal tissue, which may behave differently in breast tissue in terms of inflammatory response, integration, and long-term support.

Internal bra mesh products have been marketed for off-label use in breast surgeries despite lacking FDA approval, leading to increased scrutiny and lawsuits.

Products from multiple manufacturers have come under review in this context.

Mesh products associated with Becton Dickinson and Company, including resorbable materials used in reconstructive settings, are examined alongside other devices used in similar procedures.

DuraSorb Monofilament Mesh is another product that has been used in breast surgeries but has not received specific FDA approval for these applications.

Product liability claims involving surgical mesh used in breast procedures generally center on several recurring allegations:

• Failure to study breast-specific use: Manufacturers are alleged to have marketed mesh products, including biologic meshes and synthetic materials, without conducting adequate clinical studies on their safety and effectiveness in breast reconstruction.
• Failure to warn: Claims often assert that patients and health care providers were not clearly warned that these products were not cleared or specifically evaluated for use in breast procedures.
• Off-label promotion: Some lawsuits allege that manufacturers promoted the use of mesh in internal bra procedures despite the absence of regulatory clearance for breast-specific applications.
• Understated complication risks: Reported complications include infection, mesh failure, and tissue death, along with reconstruction breakdown requiring additional surgery. Claims may argue that complication rates were higher than disclosed.
• Design and material concerns: Lawsuits may examine whether materials, including those derived from animal tissue or used in biologic meshes, perform differently when used to support breast tissue compared to other anatomical uses.

These claims are typically brought under product liability law, including failure-to-warn and defective design theories, along with negligence-based claims where supported by the facts.

A complication alone does not establish liability.

These cases depend on whether the product, its warnings, or how it was used in breast reconstruction contributed to the outcome and required additional treatment.

Do You Qualify For A Breast Mesh Lawsuit?

You may qualify to file a breast mesh lawsuit if you received an internal bra mesh implant during breast reconstruction, augmentation, or revision surgery and experienced serious complications or injuries that required surgery to fix.

This applies to procedures where mesh was used to reinforce the breast or support an implant and the outcome required more than routine recovery.

The patients being evaluated under these claims are usually those who underwent implant-based reconstruction after mastectomy, revision of a prior reconstruction, or cosmetic breast surgery where mesh was placed to hold implant position or strengthen the breast pocket.

The situations that fall within this group involve complications that required further medical or surgical treatment, including:

• Infection involving the mesh or implant, including abscess or persistent inflammation
• Seroma requiring drainage, aspiration, or repeat procedures
• Wound breakdown, delayed healing, or tissue necrosis
• Capsular contracture causing firmness, distortion, or pain
• Implant malposition linked to loss of internal support
• Mesh migration, exposure, or erosion through tissue
• Removal of the mesh or implant, or revision of the reconstruction

These claims are evaluated by product liability attorneys and medical experts who review whether the complication required corrective treatment such as drainage, operative intervention, removal of the mesh or implant, or repeat reconstruction.

They also examine how the mesh was used during the procedure and what information was provided before surgery, including whether the patient was told that the mesh was not specifically cleared or studied for use in breast procedures and the risks associated with that use.

Evidence in an Internal Bra Mesh Claim

If your situation involves the complications described above, the next step is establishing proof.

Medical records, imaging, and operative notes help establish a clear connection between the mesh and the complications you experienced.

Strong evidence is essential in a breast mesh lawsuit because it documents exactly which product was used and how your injuries developed over time.

These claims rely on medical, surgical, and supporting documentation, including the following:

• Medical records and imaging: Detailed records documenting complications such as infection, seroma, capsular contracture, or tissue necrosis, along with imaging showing fluid collections, implant malposition, or structural changes.
• Operative reports and surgical records: Records from the original procedure identifying the mesh used, how it was placed, and whether it was used to support the implant or breast pocket.
• Revision or removal surgery records: Operative notes and follow-up documentation showing corrective procedures such as mesh removal, debridement, capsulectomy, or implant exchange.
• Device identification records: Documentation identifying the specific mesh product, including manufacturer, material composition such as P4HB, and lot or catalog details.
• Pathology and laboratory findings: Clinical evidence of infection, inflammatory response, foreign body reaction, or tissue damage associated with the mesh.

Medical records, imaging, and pathology findings are then reviewed to document complications such as seroma, infection, implant malposition, or tissue damage and when those conditions developed after surgery.

Revision surgery records and physician findings are used to determine whether the complication required mesh removal, capsulectomy, or reconstruction revision, and whether those procedures were medically linked to mesh performance, placement, or integration within the breast tissue.

Potential Compensation in Internal Bra Mesh Lawsuits

Damages represent the physical, emotional, and financial losses a patient experiences because of mesh-related injuries.

In breast mesh claims, compensation is evaluated based on the full treatment course, including whether complications such as infection, seroma, capsular contracture, mesh displacement, or tissue necrosis required intervention like drainage, IV antibiotics, operative washout, mesh removal, or reconstruction revision.

The value of a claim depends on how the condition progressed after implantation, the number and type of corrective procedures performed, and whether the reconstruction outcome was altered, failed, or could not be restored.

Damages in a breast mesh lawsuit may include:

• Medical expenses: Includes hospital treatment, imaging, antibiotics, drainage of fluid collections, surgical washout, mesh removal, capsulectomy, implant exchange, and follow-up care across multiple procedures.
• Lost income: Covers time away from work during recovery, including repeated surgical interventions, extended healing periods, or complications requiring ongoing care.
• Reduced functional capacity: Reflects limitations in upper body movement, physical activity, or daily tasks following multiple surgeries or unresolved complications.
• Pain and physical complications: Encompasses persistent pain, infection, inflammatory response, implant malposition, or ongoing symptoms that require continued monitoring or treatment.
• Disfigurement or reconstruction outcome: Addresses permanent changes such as asymmetry, contour deformities, skin damage, or cases where reconstruction fails or cannot be restored despite revision.
• Emotional distress: Relates to the psychological impact of failed reconstruction, repeated procedures, prolonged recovery, or visible changes in appearance.
• Future medical care: Accounts for anticipated revision surgeries, delayed reconstruction, or long-term monitoring where complications continue.

TorHoerman Law: Investigating Breast Mesh Implants and Injuries

Breast mesh cases involve a sequence of surgical decisions, product use, and medical outcomes that develop over time.

When a procedure leads to complications requiring additional treatment, revision surgery, or changes in reconstruction, the situation often extends beyond routine recovery and requires closer review of what was used during surgery and how the outcome progressed.

At that stage, evaluating whether the complication is linked to the mesh, its placement, or its performance is not a simple medical question.

It requires an experienced attorney with a background in medical device and product liability cases to review operative records, identify the mesh product used, and assess whether the course of treatment supports a claim.
