Abstract
Abstract A vascular graft comprises a perforate tubular compressible frame having a fabric liner disposed over at least a portion of the frames lumen. The graft may be used in combination with a base structure to form a bifurcated graft in situ . The base structure compresses a compressible frame having a fabric liner which defines a pair of divergent legs. The base structure is positioned within the aorta so that one leg enters each iliac. The tubular grafts can then be introduced into each leg to form the bifurcated structure. A graft delivery catheter includes a controllably flared sheath which facilitates recapture of a partially deployed graft.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
59 words
A graft comprising: a perforate tubular frame having a proximal end, a distal end, and a lumen therebetween; and an inner liner extending from a near-proximal location on the lumen to a near-distal location on the liner, wherein the liner covers the lumen of the tubular frame over the entire distance from said near-proximal location to said near-distal location.
Claim 2
Dependent Claim
71 words
A graft as in claim 1, wherein the tubular frame comprises a plurality of radially compressible band members, wherein adjacent band members are jointed to each other at diametrically opposed points which are rotationally staggered to enhance flexibility of the frame, or wherein at least some adjacent band members are not directly connected to each other, and wherein the band members are captured between the inner liner and an outer liner.
Claim 3
Dependent Claim
18 words
A graft as in claim 1, wherein the tubular frame comprises a plurality of laterally compressible axial members.
Claim 4
Dependent Claim
17 words
A graft as in claim 3, wherein the axial members each comprise a plurality of diamond-shaped elements.
Claim 5
Dependent Claim
24 words
A graft member as in claim 3 or 4, wherein the axial members are captured in between the inner liner and an outer liner.
Claim 6
Dependent Claim
68 words
A graft as in one of the claims 1 to 5, wherein the liner is circumferentially sealed to the perforate tubular frame at at least one of said near-proximal and near-distal locations, and is spaced-inward from an end of the perforate tubular frame by a distance in the range from 1 mm to 20 mm, wherein at least one terminal portion of the perforate tubular frame remains uncovered.
Claim 7
Independent Claim
96 words
A system for forming a bifurcated graft in situ , said system comprising a bifurcated base structure including a proximal anchor which defines a common flow lumen and a pair of connector legs which define divergent flow lumens from the common flow lumen; a first tubular graft which can be anchored within a first of the connector legs to form a continuous extension of the first divergent flow lumen; and a second tubular graft which can be anchored within a second of the connector legs to form a continuous extension of the second divergent flow lumen.
Claim 8
Dependent Claim
106 words
A system as in claim 7, wherein the proximal anchor of the bifurcated base structure comprises a radially compressible perforate tubular frame having a proximal end, a distal end, and a lumen therebetween, and wherein the pair of connector legs comprise a liner secured within the tubular frame and having a pair of legs which extend distally from the tubular frame, and wherein at least one of the first and second tubular grafts comprises (a) a radially compressible perforate tubular frame having a proximal end, a distal end, and a lumen therebetween and (b) a liner extending over an interior lumen surface of the tubular frame.
Claim 9
Dependent Claim
73 words
A delivery catheter for a radially compressible graft or stent, said catheter comprising: an elongate flexible shaft having a proximal end and a distal end; a retaining structure near the distal end of the shaft which holds the graft or stent on the shaft; and a sheath slidably received over the shaft to radially compress the graft or stent while said graft or stent is held on the shaft by the retaining structure.
Claim 10
Dependent Claim
74 words
A delivery catheter as in claim 9, wherein the sheath has an outwardly tapered distal end to facilitate proximal and distal motion over the graft or stent, wherein the outward taper is fixed or deployable, and wherein the retaining structure comprises a pair of spaced-apart locking stays on the shaft and a pull wire which extends through the locking stay and through the graft or stent to hold said graft or stent in place.
