Abstract:
A stent delivery system used for delivering a stent of predetermined size comprising in combination:a catheter having a shaft, the shaft having a diameter, and a expandable means associated therewith at a distal part of the shaft, the expandable means having an expanded state and a contracted state, the catheter further including mounting and retaining means providing a seat for supporting and receiving a stent on the expandable means for radial expansion of the stent of said predetermined size upon expansion of the expandable means, the mounting and retaining means including at least two axially spaced mounting bodies carried on the shaft inside the expandable means, whereby the diameter of the shaft, when the expandable means is in its contracted state, are increased at the distal part of the shaft for facilitating the mounting and retaining of the stent of said predetermined size, wherein when a stent of said predetermined size is crimped onto the catheter it will be seated over the at least two mounting bodies and wherein a portion of the stent of said predetermined size between the mounting bodies would be crimped to a lesser diameter than that of the mounting bodies when said stent of said predetermined size is crimped onto the catheter.
