• Applicant: Biomet, Inc.
• Product Code: MAI · Orthopedic
• Decision Date: Jun 23, 1999
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 888.3030
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The RC Buttress is intended for use to protect the suture during its use in transosseous bone tunneling in the repair of rotator cuff tears of the shoulder. The RC Buttress prevents the suture from pulling through the bone bridge between adjacent suture holes.

Device Story

RC Buttress is a surgical implant used during rotator cuff repair. It functions as a mechanical reinforcement to prevent sutures from cutting through or pulling out of the bone bridge created during transosseous tunneling. The device is manufactured from LactoSorb, a bioresorbable copolymer of lactic and glycolic acids. It is intended for use by surgeons in an operating room setting. The device degrades via hydrolysis into lactic and glycolic acids, which are metabolized by the body, eliminating the need for removal. By protecting the suture-bone interface, it aims to improve the stability of the repair.

Clinical Evidence

No clinical data provided. Biocompatibility of the LactoSorb material is supported by prior animal and clinical studies in soft and bone tissue.

Technological Characteristics

Material: LactoSorb (synthetic polyester copolymer of lactic and glycolic acids). Principle: Bioresorbable mechanical reinforcement. Form factor: Buttress implant for suture protection. Sterilization: Not specified.

Indications for Use

Indicated for patients undergoing rotator cuff repair surgery requiring transosseous bone tunneling; used to protect sutures from pulling through the bone bridge.

Regulatory Classification

Identification

Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.

Device Name: RC Buttress

The RC Buttress is intended for use to protect the suture during its use in transosseous bone tunneling in the repair of rotator cuff tears of the shoulder. The RC Buttress prevents the suture from pulling through the bone bridge between adjacent suture holes.

The RC Buttress is made of LactoSorb®, which is comprised of bioresorbable and biocompatible polymers that have been used in surgical procedures for years. The LactoSorb® resorbable copolymer is synthetic polyester derived from lactic and glycolic acids. Polylactic/polyglycolic acid copolymer degrades and resorbs In Vivo by hydrolysis into lactic and glycolic acids, which are then metabolized by the body. The LactoSorb® material has been found to be biocompatible in animal and clinical studies in both soft tissue and bone tissue.
