CATHETER BALLOON SYSTEMS AND METHODS

摘要

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 (1220 and a first balloon (1226) associated with the main catheter shaft, a side sheath (1224) and a second balloon (1220) associated with the side sheath, and a stent (1212) including a generally cylindrical body and a branch portion (1230). 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.
