Intended Use

Intended for implantation to reinforce soft tissue where weakness exists and for surgical repair of damaged or ruptured soft tissue membranes. Specifically indicated for: Plastic and reconstructive surgery; Muscle flap reinforcement; Hernia repair including abdominal, inguinal, femoral, diaphragmatic, scrotal, umbilical, and incisional hernias; Suture-line reinforcement; Reinforcement of the rotator cuff, patellar, Achilles, biceps, quadriceps, or other tendons. Porcine Dermal Matrix is not intended to replace normal body structure or provide the full mechanical strength to support tendon repair of the rotator cuff, patellar Achilles, biceps, quadriceps, or other tendons.

Device Story

Porcine Dermal Matrix is a sterile, single-use, hydrated, non-crosslinked porcine-derived dermal tissue. It is used by surgeons in clinical settings to reinforce soft tissue weaknesses or repair damaged/ruptured membranes. The device acts as a scaffold for tissue reinforcement; it does not provide full mechanical strength for tendon repairs, which must be supported by sutures or bone anchors. The device is provided in various sizes and thicknesses. It is implanted during surgical procedures to assist in reconstructive or hernia repair workflows. By providing a biological matrix, it supports the patient's natural healing process in soft tissue applications.

Clinical Evidence

Bench testing only. Biocompatibility testing conducted per ISO 10993-1, including MEM Elution Assay, Bacterial Mutagenicity, Acute Systemic Injection, Guinea Pig Maximization, Intracutaneous Reactivity, Materials Mediated Rabbit Pyrogen, and 8-, 13-, and 6-month intramuscular implant studies. The device met all requirements.

Technological Characteristics

Non-crosslinked porcine dermis (epidermal and subdermal layers removed). Hydrated, sterile, single-use. Biocompatibility per ISO 10993-1. No electronic or software components.

Indications for Use

Indicated for patients requiring soft tissue reinforcement or repair of damaged/ruptured soft tissue, including plastic/reconstructive surgery, muscle flap reinforcement, hernia repair (abdominal, inguinal, femoral, diaphragmatic, scrotal, umbilical, incisional), suture-line reinforcement, and tendon reinforcement (rotator cuff, patellar, Achilles, biceps, quadriceps). Contraindicated as a replacement for normal body structure or as the sole provider of mechanical strength for tendon repairs.

Regulatory Classification

Identification

Surgical mesh is a metallic or polymeric screen intended to be implanted to reinforce soft tissue or bone where weakness exists. Examples of surgical mesh are metallic and polymeric mesh for hernia repair, and acetabular and cement restrictor mesh used during orthopedic surgery.
