Zusammenfassung:	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.
