Device is anatomically designed with proximal and distal stems pre-flexed at 30° to mimic the natural flexion stance of the human hand. Constructed from flexible, injection-molded, medical-grade silicone elastomer. Implanted without bone cement. Used by orthopedic surgeons in clinical settings to restore joint function in patients with arthritis. Provides a mechanical replacement for damaged joints, potentially improving patient mobility and reducing pain. ## Clinical Evidence No clinical data provided; substantial equivalence is supported by performance testing and analyses. ## Technological Characteristics Single-component hinged prosthesis; material: medical-grade silicone elastomer; design: anatomically pre-flexed at 30°; implantation: cementless; form factor: finger joint implant. ## Regulatory Identification A finger joint polymer constrained prosthesis is a device intended to be implanted to replace a metacarpophalangeal or proximal interphalangeal (finger) joint. This generic type of device includes prostheses that consist of a single flexible across-the-joint component made from either a silicone elastomer or a combination pf polypropylene and polyester material. The flexible across-the-joint component may be covered with a silicone rubber sleeve. ## Predicate Devices - DePuy Silicone MCP ([K970544](/device/K970544.md)) ## Reference Devices - Sutter Avanta MCP Joint Prosthesis - Dow Corning Wright Swanson Finger Joint Implant ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

(Class II) | | | PRODUCT CODE: | 87 KYJ | | | PANEL: | Orthopedic Devices | | ### PREDICATE DEVICE: The DePuy Silicone MCP (K970544), which was determined by the FDA to be substantially equivalent to the Sutter Avanta MCP Joint Prosthesis and the Dow Corning Wright Swanson Finger Joint Implant on September 12, 1997. #### DEVICE DESCRIPTION: The Ascension Silicone MCP is an anatomically designed, single-use, one-component hinged prosthesis designed to be implanted without hone cement across the metacarpophalangeal joint. It is made from flexible, injection-molded, medical grade silicone elastomer. The proximal and distal stems of the Ascension Silicone MCP are pre-flexed at 30° to match the approximate natural 30° flexion stance of the relaxed human hand. ### INTENDED USE: The Ascension® Silicone MCP is intended for cementless replacement of the metacarpophalangeal (MCP) joint of the finger where disabled by rheumatoid, degenerative, or traumatic arthritis. #### BASIS OF SUBSTANTIAL EQUIVALENCE: Performance tests and analyses demonstrate that the Ascension® Silicone MCP is substantially equivalent to the predicate device. {1}------------------------------------------------ DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/1/Picture/2 description: The image shows the logo for the U.S. Department of Health and Human Services.

Wolfarth Senior Regulatory Affairs Specialist Ascension Orthopedics, Inc. 8200 Cameron Road, Suite C-140 Austin, Texas 78754-3832 Re: K022892 Trade/Device Name: Ascension® Silicone MCP Regulation Number: 21 CFR 888.3230 Regulation Name: Finger joint polymer constrained prosthesis Regulatory Class: Class II Product Code: KYJ Dated: August 29, 2002 Received: August 30, 2002 Dear Mr. Wolfarth: We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations. Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050. {2}------------------------------------------------ ## Page 2 - Mr. Robert M. Wolfarth This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification.
