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.
Claims18
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.
A bifurcated stent, comprising:
- a) a first sheet having a first edge, a second edge, a third edge, and a fourth edge;
- b) a second sheet having a first edge, a second edge, a third edge, and a fourth edge;
- c) a third sheet having a first edge, a second edge, a third edge, and a fourth edge;
- d) said second edge of said first sheet attached to said third edge of said first sheet to form a tubular first leg portion having a proximal end and a distal end;
- e) said second edge of said second sheet attached to said third edge of said second sheet to form a tubular second leg portion having a proximal end and a distal end;
- f) said second edge of said third sheet attached to said third edge of said third sheet to form a tubular stem portion having a proximal end and a distal end;
- and
- g) said proximal end of said first leg portion and said proximal end of said second leg portion attached to said distal end of said stem portion.
