Intended Use

The Surgi-Wrap MAST Tendon Sheet is indicated for the management and protection of tendon injuries in which there has been no substantial loss of tendon tissue. The resorbable Protective Film minimizes tissue attachment to the device in case of direct contact with the tissues. The Surgi-Wrap MAST Tendon Sheet is also indicated for reinforcement of soft tissues repaired by suture or suture anchors, during tendon repair surgery, including reinforcement of the rotator cuff, patellar, Achilles, biceps, quadriceps, or other tendons. Surgi-Wrap MAST Tendon Sheet 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. The Surgi-Wrap MAST Tendon Sheet reinforces soft tissue and provides a remodelable scaffold that is replaced by the patients own soft tissue. The device is indicated for open and laparoscopic / endoscopic procedures. Laparoscopic / endoscopic procedures are limited to sizes from 0.02mm - 0.2mm in thickness.

Device Story

Resorbable implant in sheet form; manufactured from poly (L-lactide-co-D,L-lactide) 70:30 (PLA). Device is malleable when heated to ~55°C; cut to shape intra-operatively; placed on, under, or around tendon anatomy. Used alone or with soft tissue fixation devices (sutures/anchors). Provides remodelable scaffold for soft tissue reinforcement; minimizes tissue attachment. Used in open and laparoscopic/endoscopic surgical procedures by physicians. Benefits patient by reinforcing repair site and reducing adhesions; replaced by patient's own tissue over time.

Clinical Evidence

Animal studies conducted to demonstrate safety and efficacy. Bench testing included aging studies and mechanical strength testing, confirming performance under indicated conditions. Thermal testing at 60°C confirmed viscosity stability for intra-operative shaping.

Technological Characteristics

Resorbable sheet; poly (L-lactide-co-D,L-lactide) 70:30 (PLA). Thickness 0.02mm to 1.0mm. Malleable when heated to ~55°C. Provided in various shapes/sizes (25mm x 25mm to 500mm x 500mm). Non-electronic, mechanical implant.

Indications for Use

Indicated for management and protection of tendon injuries without substantial tissue loss; reinforcement of soft tissues repaired by suture/anchors during tendon repair (rotator cuff, patellar, Achilles, biceps, quadriceps, etc.). Indicated for open and laparoscopic/endoscopic procedures.

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

#### Design Characteristics

The MAST Biosurgery Surgi-Wrap MAST Tendon Sheet is a resorbable implant in sheet form manufactured from poly (L-lactide-co-D,L-lactide) 70:30 (PLA). The Surgi-Wrap MAST Tendon Sheet can be cut with scissors to the desired shape and size. The Surgi-Wrap MAST Tendon Sheet Sheet is fully malleable when heated to approximately 55℃ (for example, by the use of sterile hot water), and thus can be conformed three dimensionally to most any anatomical orientation. The Surgi-Wrap MAST Tendon Sheet can be used either alone or in conjunction with soft tissue fixation devices such as resorbable sutures, which can also serve to fixate the Surgi-Wrap MAST Tendon Sheet and prevent dislocation. The Surgi-Wrap MAST Tendon Sheet may be used in conjunction with various MAST Biosurgery Class I manual instruments (forceps, scissors, clamps, etc.).

The MAST Biosurgery Surgi-Wrap MAST Tendon Sheet is provided in various shapes such as rectangles, ovals, and circles and will be provided in other shapes and sizes as needed for particular surgical procedures. The MAST Biosurgery Surgi-Wrap MAST Tendon Sheet is provided in sheets of 25mm x 25mm to 500mm x 500mm and will be provided in other shapes and sizes as needed for particular surgical procedures. The thickness of the MAST Biosurgery Surgi-Wrap MAST Tendon Sheet ranges from 0.02 mm to 1.0 mm according to the region to be treated. The MAST Biosurgery Surgi-Wrap MAST Tendon Sheet is provided in solid sheets. The borders of the sheets may be aligned with holes to attach suture material.

#### Material Composition

The MAST Biosurgery Surgi-Wrap MAST Tendon Sheet is fabricated from polylactic acid (PLA).

#### In Vitro Testing

The MAST Biosurgery Surgi-Wrap MAST Tendon Sheet is intended to be heated in the surgical suite to temperatures above the material's glass transition temperature to facilitate shaping to anatomic structures. Therefore, testing was performed to determine the effect of prolonged heating in saline at 60°C on inherent viscosity. The testing demonstrates that viscosity stayed within an appropriate range over 120 minutes. The relatively brief exposure anticipated during the surgical preparation of MAST Biosurgery Surgi-Wrap MAST Tendon Sheet is not expected to have a significant effect on its mechanical properties.

Aging testing was performed on MAST Biosurgery Surgi-Wrap MAST Tendon Sheet. Testing demonstrated that the MAST Biosurgery Surgi-Wrap MAST Tendon Sheet is strong enough for the indications for use.

Mechanical testing was performed on the MAST Biosurgery Surgi-Wrap MAST Tendon Sheet which determined the MAST Biosurgery Surgi-Wrap MAST Tendon Sheet to be substantially equivalent to the mechanical strengths of the predicate devices under indication for use conditions.

### Design and Materials

The physical designs of the MAST Biosurgery Surgi-Wrap MAST Tendon Sheet and the MAST Biosurgery Surgi-Wrap MAST Bioresorbable Sheet (K061473), Integra LifeSciences Tendon Wrap (K053655), TEI Biosciences Tissue Repair Matrix, (K060989) and S. Jackson Supra FOIL Smooth Nylon foil Sheets (K973379) predicate devices are substantially equivalent as they are all flexible and malleable sheets provided in various sizes that they can be cut to shape intra-operatively and subsequently placed on, under, and around tendon anatomy. The MAST Biosurgery Surgi-Wrap MAST Tendon Sheet and the MAST Biosurgery Surgi-Wrap MAST Bioresorbable Sheet (K061473), Integra LifeSciences Tendon Wrap (K053655), and TEI Biosciences TissueMend Soft Tissue Repair Matrix, (K060989) predicates all share the common design feature of being bioresorbable. The MAST Biosurgery Surgi-Wrap MAST Tendon Sheet is substantially equivalent to the S. Jackson Supra FOLL Smooth Nylon foil Sheets (K973379) and MAST Biosurgery Surgi-Wrap MAST Bioresorbable Sheet (K061473) predicates as they are all thin, semi-rigid sheets provided in sizes ranging from 25mm and 500mm x 500mm with various thicknesses ranging from 0.02mm to 1.0mm. The mechanical characteristics of the MAST Biosurgery Surgi-Wrap MAST Tendon Sheet are substantially equivalent to the predicate devices with respect to mechanical characteristics.
