Patent ID: 6860898

Claim:
A delivery system comprising: a delivery catheter including an inner tubular member having a region for mounting a stent thereon and an outer tubular member having a restraining sheath overlying said inner tubular member and adapted for axial movement with respect to said inner tubular member, the inner tubular member having an opening and a guide wire lumen extending therethrough; wherein an annular space is formed between the outer tubular member and the inner tubular member, the opening in the inner tubular member being in fluid communication with the annular space and the guide wire lumen to allow fluid to be introduced into the guide wire lumen through the opening in the inner tubular member and into the annular space which eventually flows through the distal end of the outer tubular member; and a housing assembly having a pull-back handle slidably mounted on a base, said inner tubular member having a proximal end attached to said base and said outer tubular member having a proximal end attached to said pull-back handle to allow movement of said pull-back handle proximally to retract said restraining sheath proximally from the mounted stent while the inner tubular member remains stationary.
