Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
110 words
A method of interfacing a surgically implanted prosthetic or biological implant from contact with the surface of resected bone comprising interposing a barrier layer of glutaraldehyde-fixed pericardial tissue at the interface of said resected bone and said implant, such that the fibrous surface of the fixed pericardial tissue is disposed in direct contact with the resected bone to allow for bone tissue ingrowth into said fibrous surface; said tissue being further treated such that it is substantially resistant to calcification; and said layer of pericardial tissue having overall dimensions sufficient to cover at least a portion of the outer surface of said implant and a portion of said resected bone.
