    摘要： A portion of a covered stent is encapsulated with ePTFE, so that the unencapsulated portion, which is covered by a single ePTFE covering, imparts an unimpaired flexibility to the stent. One surface of the stent, either the luminal or abluminal surface, is covered by a single continuous layer of ePTFE, while limited regions, preferably near the ends of the stent, of the other surface are also covered by ePTFE. The regions covered by ePTFE on both surfaces become encapsulated when the ePTFE of one layer becomes bonded to second layer. By leaving a middle region of the stent unencapsulated, the stent retains flexibility similar to a bare stent, thereby reducing the loading and deployment forces.

    摘要： A method to retrieve a deployed stent in a blood vessel. In one embodiment, the method includes the introduction of a retrieval stent within the lumen of the deployed stent, enlarging the retrieval stent to contact a surface of the deployed stent and contracting the retrieval stent which in turn causes the deployed stent to contract for removal from the blood vessel. The retrieval stent may contain one or more fluid passageways through which heated or cooled fluid can circulate and may be connected to a catheter for circulation of the fluid. Fluid flow may be regulated by a valve or valve assembly incorporated in the stent and/or the catheter.
