First Claim
Patent Images
1. A prosthesis capable of being carried through a patient'"'"'s vasculature over an expandable balloon and of being deployed at an ostium opening from a first body lumen to a second body lumen, the prosthesis comprising:
- a radially expansible support having a cylindrical body extending between a distal end and a proximal end of the support and along a longitudinal axis of the prosthesis, the support configured to be deployed completely in the first body lumen;
a plurality of elongate members extending axially from either the proximal or distal end of the support and disposed along the longitudinal axis, the elongate members configured to extend across the ostium opening and into the second body lumen, wherein one or more of the elongate members have a shorter length along the longitudinal axis than other elongate members of the plurality of elongate members; and
at least one circumferential member spaced from the radially expansible support and coupled with at least one of the other elongate members,wherein each of the one or more elongate members having a shorter length comprises less material than each of the other elongate members.

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