Intended Use

The ReGen Collagen Scaffold (CS) is intended for use in surgical procedures for the reinforcement and repair of soft tissue injuries of the medial meniscus. In repairing and reinforcing medial meniscal defects, the patient must have an intact meniscal rim and anterior and posterior horns for attachment of the mesh. In addition, the surgically prepared site for the CS must extend at least into the red/white zone of the meniscus to provide sufficient vascularization. The CS reinforces soft tissue and provides a resorbable scaffold that is replaced by the patient's own soft tissue. The CS is not a prosthetic device and is not intended to replace normal body structure.

Device Story

Resorbable collagen matrix; bovine type I collagen; semi-lunar shape; triangular cross-section. Used in surgical procedures for medial meniscus repair; surgeon trims device to fit defect. Acts as scaffold for patient's own tissue ingrowth; resorbs over time. Not a permanent prosthetic. Used in clinical/surgical settings by orthopedic surgeons. Benefits patient by reinforcing damaged tissue and facilitating natural tissue regeneration.

Clinical Evidence

Prospective, randomized multicenter clinical trial (IDE) with 311 patients (157 acute, 154 chronic). Mean follow-up 59 months. Data supported by publication in Journal of Bone and Joint Surgery. Evidence demonstrates safety and effectiveness for meniscal reinforcement.

Technological Characteristics

Resorbable matrix composed primarily of bovine type I collagen. Semi-lunar shape with triangular cross-section. Designed for surgical trimming. Biocompatible material.

Indications for Use

Indicated for patients requiring reinforcement and repair of soft tissue injuries of the medial meniscus. Requires intact meniscal rim, anterior and posterior horns for attachment, and surgical site extension into the red/white zone for vascularization.

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.

### Device Description

The ReGen Collagen Scaffold (CS) is a resorbable collagen matrix comprised primarily of bovine type I collagen. The CS is provided in a semi-lunar shape with a triangular cross section to be used to reinforce weakened soft tissue and provide a resorbable scaffold that is replaced by the patient's own tissue. The surgeon trims the device to the size necessary for repair of the damaged or weakened soft tissue.

## Intended Use

The ReGen Collagen Scaffold (CS) is intended for use in surgical procedures for the reinforcement and repair of soft tissue injuries of the medial meniscus. In repairing and reinforcing medial meniscal defects, the patient must have an intact meniscal rim and anterior and posterior horns for attachment of the mesh. In addition, the surgically prepared site for the CS must extend at least into the red/white zone of the meniscus to provide sufficient vascularization.

The CS reinforces soft tissue and provides a resorbable scaffold that is replaced by the patient's own soft tissue. The CS is not a prosthetic device and is not intended to replace normal body structure.

### Substantial Equivalence

The ReGen Biologics Collagen Scaffold (CS) has the same intended use and similar technological characteristics to the predicate surgical mesh devices, including; the DePuy Restore® Orthobiologic Soft Tissue Implant (K982330, K001738, K031969), the Cook Biotech SIS Fistula Plug (K050337), the TEI Biosciences TissueMend and OrthoMend (K031188, K051766), the Cook Biotech Surgisis Mesh, the Kensey Nash BioBlanket™ Surgical Mesh (K043259, K041923), the Tissue Sciences Laboratories' Permacol and ZCR Patch (K992556, K013625, K021056, K043366, K050355), the Organogenesis CuffPatch (K042809), the Cook Biotech SIS Plastic Surgery Matrix (K034039), the Artimplant Sportmesh (K052830) and the Spineology Optimesh (K014200). Any differences identified do not raise now types of safety or effectiveness questions. The questions common to all resorbable surgical meshes have been addressed in this

{2}------------------------------------------------

submission by biomechanical, biocompatibility, animal testing, and clinical studies with the device, including a prospective, randomized multicenter clinical trial that was conducted under an IDE.

This trial had two separately controlled and randomized arms; one arm consisted of 157 patients with no prior surgery to the involved meniscus (Acute) and the other 154 patients with one to three prior treatments to the involved meniscus (Chronic). Patients were followed for a mean of 59 months. Data from this IDE study and a publication in the July issue of the Journal of Bone and Joint Surgery analyzing the data from this multicenter clinical trial were used to support the substantial equivalence of this device. Data from this submission were presented at the November 14, 2008 meeting of the Orthopaedic and Rehabilitation Devices Panel Meeting for the purpose of providing FDA with advice and recommendations.

Based on the data presented, the CS is substantially equivalent to the predicate devices with respect to intended use, material of composition, and technological characteristics.
