Abstract:
1. A method of recapturing a shape memory stent that has been deployed within a vessel of a patient, wherein a lumen for the flow of blood is created by the deployed shape memory stent, comprising the steps of: inserting a recapture stent within the shape memory stent, wherein the recapture stent is attached to a catheter, the recapture stent being configured to receive and circulate fluid from the catheter without release of fluid into the vessel; enlarging the recapture stent to come in contact with the shape memory stent; cooling the recapture stent thereby reverting the shape memory stent to a smaller or relaxed state whereby the shape memory stent enfolds the recapture stent; and withdrawing the catheter to remove the recapture stent and shape memory stent.
