Abstract
Abstract An expandable intraluminal vascular graft is expanded within a blood vessel by an angioplasty balloon associated with a catheter to dilate and expand the lumen of a blood vessel. The graft may be a wire mesh tube or a thin-walled tubular member having a plurality of openings formed therein.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
164 words
An expandable intraluminal vascular graft, comprising: a tubular shaped member having first and second ends and a wall surface disposed between the first and second ends, the wall surface being formed by a plurality of intersecting elongate members, at least some of the elongate members intersecting with one another intermediate the first and second ends of the tubular shaped members; the intersecting elongate members being a plurality of thin bars, each bar having a uniform thin rectangular cross-sectional configuration; the tubular shaped member having a first diameter which permits intraluminal delivery of the tubular shaped member into a body passageway having a lumen; and the tubular shaped member having a second, expanded diameter, upon the application from the interior of the tubular shaped member of a radially, outwardly extending force, which second diameter is variable and dependent upon the amount of force applied to the tubular shaped member, whereby the tubular shaped member may be expanded to expand the lumen of the body passageway.
Claim 2
Dependent Claim
164 words
An expandable intraluminal vascular graft, comprising: a tubular shaped member having first and second ends and a wall surface disposed between the first and second ends, the wall surface being formed by a plurality of intersecting elongate members, at least some of the elongate members intersecting with one another intermediate the first and second ends of the tubular shaped members; the intersecting elongate members being a plurality of thin bars, each bar having a uniform thin rectangular cross-sectional configuration; the tubular shaped member having a first diameter which permits intraluminal delivery of the tubular shaped member into a body passageway having a lumen; and the tubular shaped member having a second, expanded diameter, upon the application from the interior of the tubular shaped member of a radially, outwardly extending force, which second diameter is variable and dependent upon the amount of force applied to the tubular shaped member, whereby the tubular shaped member may be expanded to expand the lumen of the body passageway.
Claim 3
Dependent Claim
28 words
The expandable intraluminal vascular graft of claim 1 , wherein the plurality of thin bars are fixedly secured to one another where the bars intersect with one another.
Claim 4
Dependent Claim
165 words
An expandable prosthesis for a body passageway, comprising: a tubular shaped member having first and second ends and a wall surface disposed between the first and second ends, the wall surface being formed by a plurality of intersecting elongate members, at least some of the elongate members intersecting with one another intermediate the first and second ends of the tubular shaped member; the intersecting elongate members being a plurality of thin bars, each bar having a uniform, thin rectangular cross-sectional configuration; the tubular shaped member having a first diameter which permits intraluminal delivery of the tubular shaped member into a body passageway having a lumen; and the tubular shaped member having a second, expanded diameter, upon the application from the interior of the tubular shaped member of radially, outwardly extending force, which second diameter is variable and dependent upon the amount of force applied to the tubular shaped member, whereby the tubular shaped member may be expanded to expand the lumen of the body passageway.
Claim 5
Dependent Claim
165 words
An expandable prosthesis for a body passageway, comprising: a tubular shaped member having first and second ends and a wall surface disposed between the first and second ends, the wall surface being formed by a plurality of intersecting elongate members, at least some of the elongate members intersecting with one another intermediate the first and second ends of the tubular shaped member; the intersecting elongate members being a plurality of thin bars, each bar having a uniform, thin rectangular cross-sectional configuration; the tubular shaped member having a first diameter which permits intraluminal delivery of the tubular shaped member into a body passageway having a lumen; and the tubular shaped member having a second, expanded diameter, upon the application from the interior of the tubular shaped member of radially, outwardly extending force, which second diameter is variable and dependent upon the amount of force applied to the tubular shaped member, whereby the tubular shaped member may be expanded to expand the lumen of the body passageway.
Claim 6
Dependent Claim
30 words
The expandable prosthesis for a body passageway of claim 3 , wherein the plurality of thin bars are fixedly secured to one another where the bars intersect with one another.
Claim 7
Independent Claim
111 words
An apparatus for intraluminally reinforcing a body passageway, comprising: an expandable, tubular shaped prosthesis having first and second ends, and a wall surface disposed between the first and second ends, the wall surface being formed by a plurality of intersecting elongate members, the intersecting elongate members being a plurality of thin bars, each bar having a uniform, thin rectangular cross-sectional configuration; and a catheter, having an expandable, inflatable portion associated therewith and including means for mounting and retaining the expandable, tubular shaped prosthesis on the expandable, inflatable portion. whereby upon inflation of the expandable, inflatable portion of the catheter, the prosthesis is forced radially outwardly into contact with the body passageway.
Claim 8
Independent Claim
111 words
An apparatus for intraluminally reinforcing a body passageway, comprising: an expandable, tubular shaped prosthesis having first and second ends, and a wall surface disposed between the first and second ends, the wall surface being formed by a plurality of intersecting elongate members, the intersecting elongate members being a plurality of thin bars, each bar having a uniform, thin rectangular cross-sectional configuration; and a catheter, having an expandable, inflatable portion associated therewith and including means for mounting and retaining the expandable, tubular shaped prosthesis on the expandable, inflatable portion. whereby upon inflation of the expandable, inflatable portion of the catheter, the prosthesis is forced radially outwardly into contact with the body passageway.
Claim 9
Dependent Claim
35 words
The apparatus of claim 5 , wherein the mounting and retaining means comprises retainer ring members disposed on the catheter adjacent the expandable, inflatable portion and adjacent each end of the expandable, tubular shaped prosthesis.
Claim 10
Independent Claim
115 words
An apparatus for expanding the lumen of a body passageway comprising: an expandable intraluminal vascular graft having first and second ends, and a wall surface disposed between the first and second ends, the wall surface being formed by a plurality of intersecting elongate members, the intersecting elongate members being a plurality of thin bars, each bar having a uniform, thin rectangular cross-sectional configuration; and a catheter, having an expandable, inflatable portion associated therewith and including means for mounting and retaining the expandable intraluminal vascular graft on the expandable, inflatable portion, whereby upon inflation of the expandable, inflatable portion of the catheter, the intraluminal vascular graft is forced radially outwardly into contact with the body passageway.
