Claims (2)
1. A bifurcation stent comprising a substantially cylindrical body;
two substantially cylindrical arms in fluid connection with the body and extending outwardly from the body a body cuff extending around an end of the body, said body cuff being distal to the arms;
an arm cuff extending around each arm at an end of the arm distal to the body;
a first pair of body ribs extending along the length of the stent from the arm cuff to the body cuff, said pair of ribs being interconnected by a plurality of expandable connectors;
a second pair of body ribs extending along the length of the stent from the arm cuff to the body cuff, said pair of ribs being interconnected by a plurality of expandable connectors, said second pair of body ribs extending along an opposite side of the stent relative to the first pair of body ribs;
a first pair of arm ribs extending along the length of one arm from the arm cuff to a junction point of the two arms, said pair of ribs being interconnected by a plurality of expandable connectors; and a second pair of arm ribs extending along the length of one arm from the arm cuff to the junction point of the two arms, said pair of ribs being interconnected by a plurality of expandable connectors, said second pair of arm ribs extending along an opposite arm relative to the first arm ribs.
two substantially cylindrical arms in fluid connection with the body and extending outwardly from the body a body cuff extending around an end of the body, said body cuff being distal to the arms;
an arm cuff extending around each arm at an end of the arm distal to the body;
a first pair of body ribs extending along the length of the stent from the arm cuff to the body cuff, said pair of ribs being interconnected by a plurality of expandable connectors;
a second pair of body ribs extending along the length of the stent from the arm cuff to the body cuff, said pair of ribs being interconnected by a plurality of expandable connectors, said second pair of body ribs extending along an opposite side of the stent relative to the first pair of body ribs;
a first pair of arm ribs extending along the length of one arm from the arm cuff to a junction point of the two arms, said pair of ribs being interconnected by a plurality of expandable connectors; and a second pair of arm ribs extending along the length of one arm from the arm cuff to the junction point of the two arms, said pair of ribs being interconnected by a plurality of expandable connectors, said second pair of arm ribs extending along an opposite arm relative to the first arm ribs.
2. A method of inserting a bifurcation stent into a bifurcated artery comprising:
passaging a guidewire into the artery, across the lesion and down the main branch into a distal branch vessel;
passaging a double-lumen catheter over the wire up to the level of the bifurcation;
passaging a second guidewire down the second lumen of the double-lumen catheter until the tip emerges from the distal lumen of the double-lumen catheter;
passing the guidewire down the side-branch vessel into a distal branch vessel;
withdrawing the double-lumen catheter from the artery;
passaging a birfurcation stent over both guideiwires down to the level of the bifurcation lesion;
inflating a bifurcation balloon, thereby expanding the stent, and removing the bifurcation balloon from the coronary artery.
passaging a guidewire into the artery, across the lesion and down the main branch into a distal branch vessel;
passaging a double-lumen catheter over the wire up to the level of the bifurcation;
passaging a second guidewire down the second lumen of the double-lumen catheter until the tip emerges from the distal lumen of the double-lumen catheter;
passing the guidewire down the side-branch vessel into a distal branch vessel;
withdrawing the double-lumen catheter from the artery;
passaging a birfurcation stent over both guideiwires down to the level of the bifurcation lesion;
inflating a bifurcation balloon, thereby expanding the stent, and removing the bifurcation balloon from the coronary artery.
