STENT POSITIONING AND DEPLOYMENT ASSEMBLY AND METHOD FOR TREATING A SIDE-BRANCH VESSEL

摘要

A stent positioning and deployment assembly for a constricted branched vessel is provided which includes a guide wire, a stent, a first inflatable balloon disposed within the stent and being separable from the stent, and a second inflatable balloon located proximate the first balloon. The first and second balloons each have a collapsed state and an expanded state. The inflation of the first and second balloons are controllable independently of each other, such that each of the first and second balloons may be placed into the expanded state independently of each other.
