摘要:
A radially-expandable stent for insertion into a lumen is described. The stent is composed of a radially-expandable support stent and a polymer tubular member co-axially disposed over the support stent. Tubular end sleeves are disposed around the first and second ends of the polymer-surrounded support stent to secure the tubular member and to provide other improvements.

Medical devices, such as endoprostheses, and methods of making the devices are disclosed. The medical device can include a composite cover formed of a deposited metallic film. The cover may include one or more filaments, e.g., wires, which cooperate with the film to provide desirable mechanical properties. The wires may be integrated with the film by depositing the film over the wires.

A method of handling an endoprosthesis includes providing an endoprosthesis having a deposited metal film with a thickness of about 50 microns or less and reducing the diameter of the endoprosthesis by sequentially collapsing different portions of the prosthesis. The collapsed endoprosthesis can be positioned with a lumen of an endoprosthesis delivery device. Different portions of the endoprosthesis can be sequentially and radially collapsed. For example, the endoprosthesis can be disposed within a hollow form of varying diameter.
摘要:
An endoprosthesis for deployment within a body passage includes a framework and a metallic film, which can circumferentially surround the framework or be surrounded by the framework. The framework and metallic film can be attached without using a third material, e.g., without sewing. The framework can define a circumferential recess along at least a portion of its length and circumference. The recess accommodates at least a portion of the metallic film therein.
