1. A method for forming a ureteral stent comprising:
- disposing a wire between an inner lining and an outer cover;
heating the inner lining and the outer cover such that the inner lining and the outer cover surround the wire to form an elongated member; and
forming a continuous spiral-shaped opening in the elongated member such that the elongated member is configured to move between a retracted configuration and an expanded configuration along a longitudinal axis elongated member.

Abstract
A method includes forming an elongated member having a tubular shape. The elongated member includes a sidewall that defines a lumen. A spiral-shaped opening is formed in the sidewall such that the elongated member is configured to move between a retracted configuration and an expanded configuration along a longitudinal axis of the lumen. In some embodiments, the method further includes forming a distal retention structure. The distal retention structure can be disposed at a distal end of the elongated member and can define a lumen in fluid communication with the lumen defined by the sidewall of the elongated member.
