A61F 2/82

US Classification:

623 111

Abstract:

A stent delivery catheter comprises a catheter body having a proximal end, a distal end, and a guidewire lumen extending from the distal end to at least part way between the proximal end and the distal end. A balloon is disposed over the catheter body near the distal end, and a stent is positioned over the balloon. The stent has a proximal end, a distal end, and a side opening between the proximal end and the distal end. A side sheath is coupled to the catheter body and has a proximal end, a distal end, and a guidewire lumen extending between the proximal end and the distal end. The proximal end of the side sheath is located between the proximal end of the catheter body and the balloon, and the side sheath exits out of the side opening of the stent.

Abstract:

A system for treatment of a bifurcation of a body lumen, the bifurcation having a main vessel and a branch vessel, the system includes a catheter having a main catheter shaft and a first balloon associated with the main catheter shaft, a side sheath and a second balloon associated with the side sheath, and a stent including a generally cylindrical body and a branch portion. A method is also described which includes advancing a catheter system through the main vessel, positioning a branch portion of a stent present in the system proximate to a branch vessel, and inflating first and second balloons thereby expanding a main body and branch portion of the stent.
