Abstract:
A method of deploying a stent comprising:connecting a stent of predetermined length to one end of a stent retention shaft; establishing a maximum space for relative movement of said stent retention shaft and a protective sheath by limiting relative movement of said stent retention shaft and said protective sheath to a specified region on a conjugating shaft, said maximum space being dependent on the length of said stent of predetermined size; enclosing said stent in said protective sheath through relative movement between said stent retention shaft and said sheath, wherein said relative movement is achieved by using a finger ring connected to said protective sheath and a thumb ring connected to said retention shaft; directing said stent retention shaft to a target site; exposing said stent at said target site through relative movement of said stent retention shaft and said sheath; preventing release of said stent from said stent retention shaft until performing a stent confirmation act on said shaft; and, releasing said stent from said retention shaft after performing said confirmation act.
