Abstract
An apparatus for heating and setting a stent having curved limb elements. The apparatus is a mandrel having a restraining mechanism such as pins placed on the outer surface of the mandrel or shallow grooves machined in the outer surface of the mandrel to hold and mold the stent. The mandrel helps alleviate stresses induced upon stent elements during the heating and setting process and produces a more exact stent according to the desired stent design.
