Abstract:
A delivery system for placement of a stent within a body of a patient, comprising:(a) a stent comprising a coil defining a lumen and having an initial length when in an expanded rest state, adjacent turns of the coil being positioned to substantially prevent tissue ingrowth through the turns and into the lumen when the stent is placed within the body; (b) a retaining structure sized for insertion into the body and comprising one or more pins which collapse and deform at least a portion of the stent, thereby altering the cross-sectional shape of the stent, while the stent maintains substantially its initial length; and (c) an elongated member coupled to a distal end of the retaining structure to enable insertion of the retaining structure with the collapsed and deformed stent into the body such that the collapsed and deformed stent can be deployed from the retaining structure and placed into the body of the patient while maintaining substantially its initial length.
