Means and method of implanting bioprosthetics
First Claim
1. A method of implanting bioprosthetic material in the body utilizing a length of regular connective tissue having a mesh bonded to at least one end thereof, said method comprising the following steps:
- (a) inserting said one end into a tunnel bored into a bone with the mesh in substantial contact with the living bone tissue; and
(b) fastening said tissue specimen in place to permit growth of live tissue into said mesh and then into said length of regular connective tissue to define a living bond.

Abstract
A means and method for implanting bioprosthetic material surgically, in humans or animals, is disclosed. The means comprise lengths of connective tissue such as cow tendons which are covered entirely or partially with a synthetic, looseweave mesh which is stitched to the tendon and which augments the strength of the finished heterograph (or xenograph) by permitting the existing live tissue to grow around the mesh to provide a living bond. Another implementation of the basic idea involves the use of planar patch material such as porcine pericardium to which the mesh is bonded on one side, or part of one side, this patch being used in various ways, for example, hernia repairs, dural patches, arthroplasties, tendon pulleys, gliding surfaces, and blood vessel anastamoses.

3. A modified bioprosthesis comprising:
-
(a) a length of connective tissue still connected at at least one end to the bony attachment from the donor; and (b) a mesh bonded to at least one portion of the surface of said connective tissue such that said modified bioprosthesis can be placed with at least a portion of said mesh against a living tissue surface and held in place, and said living tissue will grow into said mesh to define a living bond therewith. - View Dependent Claims (4, 5)

6. A bioprosthesis comprising:
-
(a) a tissue specimen in the form of a length of regular connective tissue treated to be non-antigenic; (b) said length having at least one end designated for attachment to a bone of a patient to repair connective tissue damage; and (c) a synthetic mesh fastened to said one end and positioned thereon to interface between the length of connective tissue and the bone, whereby bone will grow around said mesh and into said one end of connective tissue to completely integrate said prosthesis into the physiology of the patient. - View Dependent Claims (7, 8)
