The mechanical and thermal shape memory properties of Nitinol, in addition to its biocompatibility, provide significant advantages for its use in the cannula and/or stylet of a Spinal Cord Stimulation (SCS) needle. The use of Nitinol or the like will provide the physician with a needle that will not be permanently kinked or permanently bent as a result of the strain and flexing of manipulation during insertion. Once the needle is in place, it will return to its original shape, allowing passage of an SCS electrode(s) through the cannula and into the target tissue.
