Abstract
Vascular prostheses and methods of use are provided, wherein the vascular prosthesis includes a plurality of bistable unit cells configured to form a helical structure. A visualization catheter also is provided for use ensuring accurate measurement of a lesion and ensuring delivery and placement of the vascular prosthesis.
Claims25
A prosthesis comprising a helical body having a plurality of turns, the plurality of turns comprising bistable cells interconnected by bridge elements, each of the bistable cells having a thin strut including first and second ends coupled to a thick strut, the thin strut configured to transition between only a stable fully collapsed configuration and a stable fully expanded configuration.
A kit for treating occlusive disease in a body vessel, the kit comprising:
- a prosthesis comprising a helical body having a plurality of turns, the plurality of turns comprising bistable cells interconnected by bridge elements, each of the bistable cells having a thin strut including first and second ends coupled to a thick strut, the thin strut configured to transition between only a stable fully collapsed configuration and a stable fully expanded configuration;
- and
- a visualization catheter comprising an elongated body having a proximal end and a distal end and a guide wire lumen extending therethrough, a tapered portion disposed near the distal end and one or more radiopaque markers disposed on the tapered portion.
