Abstract
Abstract An implantable intraluminal prosthesis assembly is provided for use in repairing or replacing damaged or diseased portions of a blood vessel or other like vessel. The prosthesis includes an expandable stent/graft combination, with a pair of stents at either end of the graft, and further includes a plurality of struts extending between and interconnecting the stents, and radially spaced about the inner surface of the graft. As such, the implantable prosthesis is provided with internal support for the graft when in a compressed state during implantation and is further provided with radial support along the length of the graft after implantation.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
116 words
An implantable assembly comprising: an elongate, generally tubular compressible graft having opposed end portions, a pair of resiliently compressible, generally tubular wire stents of generally zig-zag configuration positioned within said tubular graft at spaced apart locations adjacent said end portions of said graft said stents having radially spaced medial and distal stent joints; and a plurality of elongate struts extending between and interconnecting said stents at alternating ones of said medial stent joints, said struts being radially spaced about the inner surface of said graft and being secured directly thereto to provide internal support to said graft when in a compressed state and to further provide radial support along the length of said graft after implantation.
Claim 2
Dependent Claim
116 words
An implantable assembly comprising: an elongate, generally tubular compressible graft having opposed end portions, a pair of resiliently compressible, generally tubular wire stents of generally zig-zag configuration positioned within said tubular graft at spaced apart locations adjacent said end portions of said graft said stents having radially spaced medial and distal stent joints; and a plurality of elongate struts extending between and interconnecting said stents at alternating ones of said medial stent joints, said struts being radially spaced about the inner surface of said graft and being secured directly thereto to provide internal support to said graft when in a compressed state and to further provide radial support along the length of said graft after implantation.
Claim 3
Dependent Claim
20 words
