Abstract
A medical device which comprises a shape memory alloy (SMA) portion which is deformable from an undeformed first configuration assumed by it in an austenitic state of the SMA to a deformed second configuration, whereby the SMA is converted into a strain-induced martensite or partial martensite. This conversion increases the temperature of transformation (A.sub.s) from an initial transformation temperature A.sub.s .degree. to a temperature A.sub.s '. When the SMA, once in the second configuration, is heated to a temperature higher than A.sub.s ', it transforms to an at least partial austenite and it transforms towards the undeformed first configuration with a decrease of A.sub.s from A.sub.s ' to A.sub.s .degree.. A.sub.s .degree. is below body temperature such that when the device is deployed in the body, after placing it in its target location with the SMA portion in the second configuration and then heating it to assume its first configuration, the SMA is stable in the at least partial austenite at body temperature.
