Abstract
A method of imparting a particular shape to a wire made of a shape memory alloy, such as a Ni-Ti alloy, which includes the steps of bending the wire inside a tubular body into the particular shape; heating the wire within the tubular body to a temperature sufficient to cause the wire to retain the particular shape; and removing the wire from the tubular body. The tubular body is made of a deformable metal, such as stainless steel or nickel-chrome alloy tubing, and includes a slit therethrough extending in its axial direction. The slit is provided to facilitate bending the tubular body and removing the wire from the tubular body.
