Indications for Use
Meso Tendon Matrix is intended for use in sports medicine procedures for the reinforcement and repair of soft tissue where weakness exists including but not limited to, rotator cuff, patellar, Achilles, biceps, quadriceps and other tendons. Meso Tendon 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. Sutures, used to repair the tear, and sutures or bone anchors used to attach the tissue to the bone, provide biomechanical strength for the tendon repair. Meso Tendon Matrix is supplied sterile and for one time use.
Device Story
Meso Tendon Matrix is a resorbable surgical mesh derived from porcine mesothelium tissue; intended for soft tissue reinforcement in sports medicine. Supplied dry in sterile double-layer packaging; hydrated by clinician with saline or autologous fluids (blood, bone marrow aspirate, platelet-rich plasma) prior to implantation. Used by surgeons in clinical settings to reinforce tendon repairs; does not provide primary biomechanical strength, which is supplied by sutures or bone anchors. Device acts as a scaffold to support natural tissue healing and remodeling. Benefits include reinforcement of weakened soft tissue during surgical repair procedures.
Clinical Evidence
No clinical data. Evidence consists of biocompatibility testing per ISO 10993-1:2009 (cytotoxicity, sensitization, irritation, toxicity, genotoxicity, hemocompatibility), viral inactivation, residual chemical assessment, and biomechanical bench testing (tensile, burst, wet tear, suture retention). Animal implant studies confirmed normal tissue healing response and remodeling capability.
Technological Characteristics
Resorbable single-layer surgical mesh derived from porcine mesothelium. Sterilized via Ethylene Oxide. Supplied dry, hydrated with saline or autologous fluids before use. Biocompatibility per ISO 10993-1:2009. Shelf life 24 months. Single-use.
Indications for Use
Indicated for reinforcement and repair of soft tissue in sports medicine procedures where weakness exists, including rotator cuff, patellar, Achilles, biceps, and quadriceps tendons. Not intended to replace normal body structure or provide full mechanical strength for tendon repair; requires use of sutures or bone anchors for biomechanical strength.
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.

## Biocompatibility and Performance Data:
Biocompatibility testing, biomechanical bench testing, characterization testing and in vivo performance testing have been conducted to evaluate the biological safety and biomechanical performance characteristics of Meso Tendon Matrix.
Biocompatibility testing was completed on the finished sterile device in accordance with the requirements of ISO 10993-1: 2009, Biological Evaluation of Medical Devices—Part 1: Evaluation and Testing within a Risk Management Process. Testing included Cytotoxicity, Sensitization, Irritation, Acute Systemic Toxicity, Genotoxicity, Hemocompatibility, Subacute Systemic Toxicity, and Chronic Systemic Toxicity. Other safety testing included a viral inactivation study and residual chemical assessment. Results indicate that the device's biocompatibility profile is acceptable.
Biomechanical testing included tensile strength, burst testing, wet tear testing, and suture retention testing. Testing results indicate that the device is equivalent to the predicate device and meets the requirements for its intended use.
Animal implant studies were performed to confirm the functionality and tissue response characteristics of the proposed device. Results indicate a normal tissue healing response and confirm the device's remodeling capability.
#### Substantial Equivalence:
Performance testing has confirmed that the Meso Tendon Matrix is substantially equivalent to the predicate device Medeor Matrix (K103787) with regard to material, intended use, principles of operation, and technological characteristics, pursuant to section 510(k).
