Abstract

A delivery system for placement of a stent within a body of a patient includes a stent, a retaining structure, and an elongated member. The stent includes a coil which defines a lumen and has an initial length when in an expanded rest state. Adjacent turns of the coil are positioned to substantially prevent tissue ingrowth through the turns and into the lumen when the stent is placed within the body. The retaining structure is sized for insertion into the body and includes one or more pins. The pins collapse and deform the stent while the stent maintains substantially its initial length. The elongated member is coupled to the retaining structure and enables insertion of the retaining structure with the stent into the body such that the stent can be deployed from the retaining structure and placed into the body while maintaining substantially its initial length.
