1. A prosthesis for placement at an ostium opening from a main body lumen to a branch body lumen, the prosthesis comprising:
- a radially expansible support configured to be deployed in at least a portion of the branch body lumen;
a plurality of longitudinal members extending from either a proximal or distal end of the support, the longitudinal members configured to be positioned in the main body lumen; and
a circumferential member spaced axially from the radially expansible support along a longitudinal axis of the prosthesis,wherein at least one of the longitudinal members further comprises a first end and a second end, the first end coupled with a portion of the prosthesis distal of the second end, and the second end coupled with the circumferential member, wherein at least one other longitudinal member is not coupled with the circumferential member,wherein the support has a first wall pattern, and the prosthesis comprises a transition portion disposed between the support and the circumferential member, the transition portion having a second wall pattern different from the first wall pattern,wherein the transition portion comprises an end coupled with the at least one of the longitudinal members, the at least one of the longitudinal members comprising a single filament coupled with the circumferential member.

Abstract
A prosthesis is disclosed for placement across an ostium opening from a main body lumen to a branch body lumen. The prosthesis comprises a radially expansible support, at least two axially elongate longitudinal members, at least one of which can be fronds, extending from an end of the support, and a circumferential member connected to at least one axially elongate longitudinal member and unconnected to at least one other axially elongate longitudinal member.

24. A prosthesis for placement at an opening from a main body lumen to a branch body lumen, the prosthesis comprising:
-
a radially expansible support configured to be deployed in at least a portion of the branch body lumen, the support adapted to provide a first radial force to support the branch body lumen; a plurality of longitudinal members extending from an end of the support, the longitudinal members configured to reach into the main body lumen when deployed; and a circumferential member spaced apart from the support and providing a second radial force less than the first radial force when deployed, the circumferential member connected to a minority of the longitudinal members and unconnected to a majority of the longitudinal members. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A prosthesis for placement at an ostium opening from a first body lumen to a second body lumen, the prosthesis comprising:
-
a radially expansible support configured to be deployed in at least a portion of the first body lumen; at least two longitudinal members extending from an end of the support, all of the longitudinal members configured to be positioned in the second body lumen when deployed; and a circumferential member spaced axially from the radially expansible support, the circumferential member connected to at least one of the longitudinal members and unconnected to at least one other longitudinal member, wherein the longitudinal members comprise an ostium scaffolding transition portion, the transition portion comprising a plurality of ends configured to open up in different directions to follow the ostium opening, one of the ends of the transition portion coupled with the at least one of the longitudinal members connected to the circumferential member. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44, 45)
