SIDE BRANCH STENTING SYSTEM USING A MAIN VESSEL CONSTRAINING SIDE BRANCH ACCESS BALLOON AND SIDE BRANCHING STENT

摘要

A side branch stenting system using a catheter/stent assembly having a balloon (25) with adjacent globular (28) and cylindrical portions and a stent (22) mounted thereon over the cylindrical portion The stent has finger-like (24) projections mounted over portion of the globular portion of the balloon. At a bifurcation site with another stent in place in the main vessel and having an opening into a side branch, the catheter/stent assembly is placed in the side branch and inflated. The cylindrical portion of the balloon expands the main stent body in the side vessel. The globular portion of the balloon inflates in the main vessel, constraining the main vessel and bending the finger-like projections around the circumference of the opening into the side branch.
