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.
