    摘要： A delivery system with sequential release mechanism and method of delivering and deploying an implantable stented device into a body lumen including a tabular body, a plurality of activation members extending from the distal end of the tubular body, and a plurality of disks. Each disk includes a proximal and distal surface, at least one stent engagement element attached to the distal surface of the disk and at least one aperture. At least one activation member attaches to the proximal surface of a first disk and at least one activation member passes through an aperture of the first disk and attaches to the proximal surface of a second disk. At least one stent engagement element attached to the distal surface of the first disk passes through an aperture of the second disk. Axially movement of the activation members causes sequential release of the stent engagement elements from a stented device.

    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.
