Intended Use

The DePuy OrthoTech Restore Orthobiologic Soft Tissue Implant is intended for use in general surgical procedures for reinforcement of soft tissue where weakness exists. The device is intended to act as a resorbable scaffold which initially has sufficient mechanical strength to assist with a soft tissue repair, but then resorbs and is replaced by the patients own tissue.

Device Story

Restore Orthobiologic Soft Tissue Implant is a round, resorbable surgical mesh; manufactured from 10 plies of porcine small intestine submucosa (SIS). SIS acts as a scaffold for new tissue formation; provides mechanical strength for soft tissue repair; resorbs over time and is replaced by patient's own tissue. Used in general surgical procedures for reinforcement of soft tissue where weakness exists. Implanted by surgeons during surgical procedures. Benefits include scaffold-mediated tissue regeneration and reinforcement of weakened soft tissue.

Clinical Evidence

No human clinical trials provided. Evidence consists of biocompatibility testing per ISO 10993 and multiple animal efficacy studies. Animal models included repair of abdominal aponeuroses, abdominal wall, fascial/capsular defects, patellar/achilles tendons, and replacement of infraspinatus tendons and cranial cruciate ligaments. Studies showed the implant served as a scaffold for new tissue formation with no evidence of material rejection.

Technological Characteristics

Round surgical mesh; 10-ply porcine small intestine submucosa (SIS). Composed primarily of water and collagen. Resorbable scaffold. Biocompatibility tested per ISO 10993. Mechanical properties evaluated via suture retention and ball burst tests.

Indications for Use

Indicated for use in general surgical procedures for reinforcement of soft tissue where weakness exists in patients requiring soft tissue 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.

## DEVICE DESCRIPTION AND INTENDED USE:

The Restore Orthibiologic Soft Tissue Implant is a round device, manufactured from 10 plys of Small Intestine Submucosa, (SIS). SIS is a bionaterial desived from porcine small intestine. SIS is composed presionshately of water and collagen. This material to the material approved in IDF. G960196 for investigational use as an Anterior Cruciate Ligament (ACL) replacement device and submitted in K974540 for Hernia Repair.

The Restore Orthobiologic Soft Tissue Implant is intended for use in general surgical procedures for reinforcement of soft tissue where weakness exists. The device is intended to act as a resorbable scaffold which initially has sufficient mechanical strength to assist with a soft tissue repair, but then resorbs and is replaced by the patients own tissue.

## BASIS OF SUBSTANTIAL EQUIVALENCE:

The DePuy Orth Tech Restore Orthobiologic Soft Tissue Implant is substantially equivalent to the above listed devices in that it is manufactured from the same matcrial (SIS. porcine small intessine submucosa) as the Sentron SIS Hernia Repair Device and the Cook Biotech Inc. SIS Wound Dressing and SIS Surgical Mesh. The material is very similar to that of the Organogenesis Graft Patch (described as cross-linked porcine collagen). It has the same intended use (reinforcing soft tissue) as the Organogenesis Graft Patch, the Bio-Vascular Supple Peri-guard, and the SIS Surgical Mesh and it has : similar design to all five of these soft tissue patches. Mechanical testing shows that the Restore Orthobiologic Soft Tissue Implant and the BioVascular Supple Periguard have comparable suture retention strength and mechanical strength as measured by ball butst tests. Biocompatibility tests, performed according to ISO 10993, other accepted standards and other appropriate test methods indicate that the SIS material is biocompatible. Numerous animal efficacy studies indicate that SIS, in various configurations is efficacious when used for soft tissue repair or soft tise ue replacement. These studies include: repair of abdominal aponeuroses and the

{1}------------------------------------------------

abdominal wall, fascial and capsular defects, and patellar and achilles tendons, and replacement of infraspinatus tendras and cranial cruciate ligaments. In all of these studies the SIS implant served as a scaffold for hew tissue formation and no evidence of rejection of the material was observed.
