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.
