Abstract

Apparatus for the affixing of prosthetic, mechanical devices to body tissue. Often referred to as a “surgical attachment ring.” At least a portion of the outside edge of said ring is substantially of a non-convex profile. The application may also characterised by the feature of pre-attached or pre-loaded sutures or by the presence of one or more suture—receiving passageways in the body of the ring.

2. A ring according to claim 1 and in which the entire outside face of the ring has a substantially non-convex profile.

3. A ring according to claim 1 and in which a portion, only, of the outside face of the ring has a non-convex profile.

4. A ring according to claim 1 and in which the outside face of the ring is symmetrical about its mid-circumferential plane.

5. A ring according to claim 1 and in which the outside face of the ring has an L-shaped profile.

6. A ring according to claim 1 and in which the outside face of the ring incorporates a number of suture cleats.

7. A ring according to claim 6 and in which the outside face of the ring comprises a number of raised ribs through which run suture-receiving passages.
