Abstract

Abstract A bifurcated stent for insertion into a bifurcated vessel such as a blood vessel. In one embodiment, a first sheet is formed into a first leg, a second sheet is formed into a second leg, a third sheet is formed into a stem, and the two legs are attached to the stem. In a second embodiment, a first sheet is formed into a member having a first leg and half of a stem, a second sheet is formed into a second member having a second leg and half of a stem, and the two stem halves are combined to form the bifurcated stent. In a third embodiment, the stent comprises two sections that are serially inserted and assembled within the vessel at the site of the bifurcation to be treated.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 180 words
A method of making a bifurcated stent, comprising the steps of: a) preparing a first sheet having a first edge, a second edge, a third edge, and a fourth edge ; b) preparing a second sheet having a first edge, a second edge, a third edge, and a fourth edge; c) preparing a third sheet having a first edge, a second edge, a third edge, and a fourth edge; d) attaching said second edge to said third edge of said first sheet to form a tubular first leg portion having a proximal end and a distal end; e) attaching said second edge to said third edge of said second sheet to form a tubular second leg portion having a proximal end and a distal end; f) attaching said second edge to said third edge of said third sheet to form a tubular stem portion having a proximal end and a distal end; and g) attaching said proximal end of said first leg portion and said proximal end of said second leg portion to said distal end of said stem portion.
Claim 2
Independent Claim 111 words
A method of making a bifurcated stent, comprising the steps of: a) preparing a first sheet having a proximal end and a distal end; b) deforming said distal end of said first sheet to form a first leg and deforming said proximal end of said first sheet to form a first stem half; c) preparing a second sheet having a proximal end and a distal end; d) deforming said distal end of said second sheet to form a second leg and deforming said proximal end of said second sheet to form a second stem half; and e) joining said first stem half to said second stem half to form a stem.
Claim 3
Independent Claim 233 words
A method of making a bifurcated stent comprising the steps a) preparing a first expandable tubular member having a proximal end and a distal end and a longitudinal bore therethrough, said first tubular member provided with a branch aperture disposed between said proximal end and said distal end, said branch aperture communicating with said longitudinal bore and said aperture sized and adapted to receive and secure a second expandable tubular member; b) delivering said first expandable tubular member to a bifurcated vessel having a first lumen and a second lumen so that said first expandable member is disposed within said first lumen and said branch aperture communicates with said second lumen; c) expanding said first expandable member in an amount sufficient to secure said first expandable member in said first lumen; d) preparing a second expandable tubular member having a proximal end and a distal end and having longitudinal bore therethrough; e) widening said branch aperture; f) delivering said second expandable tubular member into said branch aperture so that said distal end of said second expandable tubular member is disposed within said second lumen and said proximal end of said second expandable tubular member is disposed within said longitudinal bore of said first longitudinal member; and g) expanding said second expandable tubular member in an amount sufficient to secure said second expandable tubular member within said second lumen and within said branch aperture.
