Intended Use

OrthoMend Soft Tissue Repair Matrix is intended for reinforcement of soft tissues repaired by sutures or suture anchors, during tendon repair surgery, including reinforcement of the rotator cuff, patellar, Achilles, biceps, quadriceps, or other tendons. OrthoMend Soft Tissue Repair Matrix is not intended to replace normal body structure or provide the 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. OrthoMend Soft Tissue Repair Matrix reinforces soft tissue and provides a remodelable scaffold that is replaced by the patient's own soft tissues.

Device Story

OrthoMend is a sterile, remodelable collagen matrix supplied in sheet form. Used by surgeons in an OR setting to reinforce soft tissue repairs. The surgeon trims and sutures the matrix over the repair site. The device acts as a scaffold, facilitating replacement by the patient's own tissue over time. It does not provide primary mechanical strength; that is provided by sutures or bone anchors. The device is fully resorbable.

Clinical Evidence

Bench testing only. Biocompatibility assessment performed by an independent laboratory demonstrated safety via cytotoxicity, sensitization, intracutaneous reactivity, intramuscular toxicity, hemolysis, and acute systemic toxicity testing. Viral inactivation levels were also validated.

Technological Characteristics

Resorbable collagen matrix; sheet form; intended for surgical suturing. Fully resorbable over months. Biocompatible per independent laboratory testing.

Indications for Use

Indicated for reinforcement of soft tissues during tendon repair surgery (e.g., rotator cuff, patellar, Achilles, biceps, quadriceps) in patients requiring suture or bone anchor fixation. Not intended to provide primary biomechanical strength for tendon repair.

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.
