A medical device such as a stent, surgical staple, bone anchoring device or bone fixation device, intended to be deployed within the body, composes a shape memory alloy (SMA) portion with an austenitic and unaustenitic state with different memorized configurations in each of these states. The SMA which is initially in an initial configuration in which it can be placed into position within the body, can be mechanically deformed into an operational configuration in which it remains deployed within the body.
