Abstract
Medical devices and methods for placing a bifurcated stent into a bifurcating blood vessel are described herein. Also, described herein are methods for treating aorto-iliac occlusive disease. The bifurcated stent can be mounted onto a catheter comprising at least two balloons by mounting a first branch stent of the bifurcated stent onto a first balloon and a second branch stent of the bifurcated stent onto a second balloon, and a main body of the bifurcated stent onto the first balloon and second balloon.
Claims20
A system for treating a diseased bifurcating blood vessel, the system comprising:
- a bifurcated stent comprising a main body stent, a first branch stent, and a second branch stent;
- a catheter for delivering the bifurcated stent into the diseased bifurcated blood vessel, the catheter comprising:
- a first balloon and a second balloon arranged substantially in parallel;
- and
- a looped guidewire lumen that passes a guidewire through the first balloon and second balloon;
- wherein the first branch stent is crimped onto the first balloon, the second branch stent is crimped onto the second balloon, and the main body stent is crimped onto the first balloon and the second balloon.
A method for treating a diseased bifurcating blood vessel including a main vessel and two branch vessels, the method comprising:
- mounting a bifurcated stent including a main body stent and a first branch stent and a second branch stent onto a catheter having a first balloon and a second balloon;
- advancing the bifurcated stent through a first branch vessel toward a bifurcation point of the diseased bifurcating blood vessel;
- placing the bifurcated stent into the bifurcating blood vessel;
- expanding the first branch stent into the first branch vessel by inflating the first balloon;
- expanding the second branch stent into a second branch vessel by inflating the second balloon;
- and
- expanding the main body stent into the main vessel by simultaneously inflating the first balloon and the second balloon.
A balloon catheter for delivering a bifurcated stent into a bifurcated blood vessel, the balloon catheter comprising:
- a proximal hub;
- a shaft;
- a first balloon connected to the shaft;
- a second balloon in fluid communication with the first balloon, wherein the first and second balloons are arranged in a substantially parallel configuration when inserted into the bifurcated blood vessel;
- an inflation port at the proximal hub in fluid communication with the first balloon and second balloon;
- a first guidewire lumen extending through the proximal hub, the shaft, and the first balloon;
- and
- a second guidewire lumen extending through the proximal hub, the first balloon, and the second balloon.
