Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
124 words
A biocompatible insert for use in filling a fenestration that extends through an implant member wherein the fenestration is of a predetermined shape and depth, said insert comprising at least two discs made of a relatively flexible material, each of said discs having a predetermined thickness and an outer perimeter defining a shape substantially identical to the predetermined shape of said fenestration, each of said discs having a plurality of ribs integrally formed about said outer perimeter thereof and interlocking means for interlocking said discs together to form said insert so that when said insert is press-fitted within said fenestration, the combined thickness of the discs is substantially equal to said predetermined depth of the fenestration in said implant, thereby completely filling the fenestration.
Claim 2
Dependent Claim
124 words
A biocompatible insert for use in filling a fenestration that extends through an implant member wherein the fenestration is of a predetermined shape and depth, said insert comprising at least two discs made of a relatively flexible material, each of said discs having a predetermined thickness and an outer perimeter defining a shape substantially identical to the predetermined shape of said fenestration, each of said discs having a plurality of ribs integrally formed about said outer perimeter thereof and interlocking means for interlocking said discs together to form said insert so that when said insert is press-fitted within said fenestration, the combined thickness of the discs is substantially equal to said predetermined depth of the fenestration in said implant, thereby completely filling the fenestration.
Claim 3
Dependent Claim
19 words
An insert according to claim 1, wherein said discs having a shape which is substantially rectangular with rounded corners.
Claim 4
Dependent Claim
23 words
An insert according to claim 1, wherein said relatively flexible material is biocompatible and selected from the group consisting of polyurethane and silicone.
Claim 5
Dependent Claim
24 words
An insert according to claim 1, wherein said insert has a generally trapezoidal shape conforming to a substantially identical fenestration shape in the implant.
Claim 6
Dependent Claim
13 words
An insert according to claim 1, wherein said predetermined shape is substantially circular.
Claim 7
Independent Claim
108 words
A method of implanting with bone cement an implant having a fenestration of predetermined shape and depth extending therethrough, the method comprising: providing at least two discs made of a relatively flexible material, each of said discs having a predetermined thickness and an outer perimeter defining a shape of said fenestration, each of said discs having a plurality of ribs integrally formed about said outer perimeter thereof; joining the discs to form a biocompatible insert having a combined thickness being substantially equal to said predetermined depth of the fenestration in said implant; press-fitting said biocompatible insert within said fenestration to completely fill the fenestration; and implanting said prosthesis.
Claim 8
Independent Claim
108 words
A method of implanting with bone cement an implant having a fenestration of predetermined shape and depth extending therethrough, the method comprising: providing at least two discs made of a relatively flexible material, each of said discs having a predetermined thickness and an outer perimeter defining a shape of said fenestration, each of said discs having a plurality of ribs integrally formed about said outer perimeter thereof; joining the discs to form a biocompatible insert having a combined thickness being substantially equal to said predetermined depth of the fenestration in said implant; press-fitting said biocompatible insert within said fenestration to completely fill the fenestration; and implanting said prosthesis.
