Prosthesis And Deployment Catheter For Treating Vascular Bifurcations
First Claim
1. A prosthesis and deployment catheter system for treating an opening from a main body lumen to a branch body lumen, the prosthesis comprising:
- a radially expansible support, the support configured to be deployed in at least a portion of the branch body lumen;
a plurality of fronds extending axially from an end of the support and configured to be positioned across the Os and into the main body lumen; and
at least one circumferential link connecting at least a first and a second frond, the circumferential link spaced axially apart from the support;
wherein the prosthesis is mounted on a balloon catheter such that the radially expansible support is carried by a first portion of a balloon that is inflatable to a first diameter and the circumferential link is carried by a second portion of a balloon that is inflatable to a second diameter that is larger than the first diameter.

Abstract
A stepped balloon catheter prosthesis deployment system is disclosed for placement of a prosthesis across an Os opening from a main body lumen to a branch body lumen. The prosthesis comprises a radially expansible support at one end, a circumferentially extending link at the other end and at least one frond extending axially therebetween. The prosthesis is configured to be deployed from a stepped diameter balloon with the support in the branch body lumen, with the circumferentially extending link in the main lumen and the frond extendable across the Os.
