Abstract
Abstract A surgically implantable prosthesis formed from a single piece of inherently flexible elastomeric, physiologically inert material and a polyester felt pad embedded within the prosthesis and having an exposed surface to provide for ingrowth of body tissue. The one piece prosthesis is radiated to provide areas of different flexibility in accordance with the function to be performed by the prosthesis.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
83 words
A surgically imPlantable prosthesis comprising: a one-piece body of inherently flexible elastomeric, physiologically inert material, said body having an enlarged center portion and an outwardly projecting connecting portion, an enlarged edge around the outer periphery of said connecting portion, said center portion and said outwardly projecting portion having a greater density than said outer edge, and a number of polyester felt pads in said enlarged edge, each pad having an exposed section on the surface of said edge for promoting ingrowth of tissue.
Claim 2
Dependent Claim
83 words
A surgically imPlantable prosthesis comprising: a one-piece body of inherently flexible elastomeric, physiologically inert material, said body having an enlarged center portion and an outwardly projecting connecting portion, an enlarged edge around the outer periphery of said connecting portion, said center portion and said outwardly projecting portion having a greater density than said outer edge, and a number of polyester felt pads in said enlarged edge, each pad having an exposed section on the surface of said edge for promoting ingrowth of tissue.
Claim 3
Dependent Claim
70 words
A surgically implantable joint comprising: a single piece of inherently flexible elastomeric, physiologically inert material having an enlarged center portion, an outwardly projecting portion on each side of said center portion and a felt-like pad embedded in said outwardly projecting portion, said pad being wider than said outwardly extending portion whereby the edge of said pad is exposed along each edge of said outwardly extending portion to promote tissue ingrowth.
Claim 4
Dependent Claim
70 words
A surgically implantable joint comprising: a single piece of inherently flexible elastomeric, physiologically inert material having an enlarged center portion, an outwardly projecting portion on each side of said center portion and a felt-like pad embedded in said outwardly projecting portion, said pad being wider than said outwardly extending portion whereby the edge of said pad is exposed along each edge of said outwardly extending portion to promote tissue ingrowth.
Claim 5
Dependent Claim
19 words
The joint according to claim 2 wherein said outwardly projecting portions have a greater rigidity than said center portion.
