Abstract
A radially expandable device particularly adaptable for use as an endoprothesis is described along with a method of fabrication. The method begins by obtaining a number of individual, separate generally circular hoops by a number of ways, such as cutting a length of wire, forming it into a generally circular loop, and attaching the ends together. In another aspect of this method of fabrication, the individual, separate generally circular hoops are obtained by cutting the needed number from a tubing. Thereafter, a wave-like pattern is formed in each hoop, with a die, in a direction transverse the axis of the wire, creating a predetermined number of rings and attaching them at the crest point to form a stent that can be compressed for inserting into a lumen where it can be expanded to provided a needed support.
