Multi-layered stents and methods of implanting
First Claim
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; and
a 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.

Abstract
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.

9. A method of selectively constructing a multi-layered stent assembly comprising a first stent at least partially coaxially positioned within a second stent, the method comprising the steps of:
- selecting at least one material property of the first stent and selecting at least one material property of the second stent that is different from the at least one material property of the first stent, wherein a combination of the at least one material property of the first and second stents provide a stent assembly having a combined material property for the stent assembly.
