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.

Abstract: A prosthesis is disclosed for placement across an ostium opening from a main body lumen to a branch body lumen. The prosthesis has a radially expansible support and a bifurcation traversing portion. The radially expansible support is configured to be deployed in at least a portion of the branch body lumen. The bifurcation traversing portion has a biostable portion having a first end and a second end. The first end is located adjacent to the radially expansible support. The bifurcation traversing portion also has a biodegradable portion having a first end coupled with the second end of the biostable portion. The biodegradable portion has a second end disposed at an end of the prosthesis opposite the radially expansible support. When deployed, the bifurcation traversing portion extends from the radially expansible support across a bifurcation and into a main body lumen such that the carina is supported thereby.

Abstract: A urethral scaffold is provided for expanding a portion of the urethra that extends through the prostate. The scaffold is expandable and has a plurality of undulating circumferential members disposed between a proximal end and a distal end of the scaffold. A central section of the scaffold has a width that exceeds the width at the distal end of the scaffold. The scaffold is made of a material that reacts with urine or with tissue surrounding the urethra to reduce the volume of the scaffold such that the scaffold can self-explant without an interventional procedure.
