MULTI-LAYERED STENTS AND METHODS OF IMPLANTING

摘要

A method of percutaneously delivering a multi-layered stent assembly to a desired implantation location of a patient including the steps of radially compressing a multi-layered stent assembly to a compressed size for implantation in a patient, the multi-layered stent assembly including a first stent, a second stent coaxially positioned within at least a portion of a length of the first stent, and a valve, wherein the first stent comprises at least one different material property than the second stent. The method further includes delivering the multi-layered stent assembly to the desired implantation location of the patient using a delivery system and substantially simultaneously expanding the first stent and the second stent of the multi-layered stent assembly at the desired implantation location to a radially expanded size that is larger than the compressed size.

1. A method of percutaneously delivering a multi-layered stent assembly to a desired implantation location of a patient, the method comprising the steps of:
radially compressing a multi-layered stent assembly to a compressed size for implantation in a patient, the multi-layered stent assembly comprising:
a first independent stent comprising a first discrete end and a second discrete end;a second independent stent comprising a first discrete end and a second discrete end and coaxially positioned within at least a portion of a length of the first stent; anda valve attached within an internal area of the second stent;wherein the first stent comprises at least one different material property than the second stent; and delivering the multi-layered stent assembly to the desired implantation location of the patient using a delivery system; and substantially simultaneously expanding the first stent and the second stent of the multi-layered stent assembly at the desired implantation location to a radially expanded size that is larger than the compressed size.
