Patent abstract
A needle device which is manufactured from shape memory or pseudo-elastic materials, such as Nickel Titanium alloys, is provided which may be formed and used repeatedly without adverse effects, such as permanent deformation or fatigue failure. The device in accordance with the present disclosure may be provided having an initial shape which a doctor may bend to a desired shape. The device may be easily returned to its initial shape after use by heating the device above a predetermined sterilization temperature. This cycle may be repeated during subsequent uses, substantially extending the life of the instrument, due to the reduced work hardening and enhanced fatigue properties of the Nickel Titanium device.
