Abstract: A guidewire loaded stent for delivery through a catheter is described herein. The stent delivery assembly can deliver and place a stent within tortuous regions of the body which are accessible to guidewires but inaccessible to stenting catheters. The assembly comprises a guidewire covered in part by a retractable sheath and a radially expandable stent near or at the distal end of the guidewire. The whole assembly is advanced through conventional catheters or it may be used alone. In either case, when the stent is adjacent to a treatment site within the body, the sheath is retracted proximally to expose the stent for radial expansion into contact with the vessel wall. Radio-opaque marker bands are optionally located on either side or both sides of the stent on the guidewire body to aid in visual placement. The assembly can optionally include an expandable balloon on the guidewire for different treatment modalities.

Abstract: A prosthesis delivery system including a prosthesis mounted on an elongate member. The prosthesis has a locking member positioned on the prosthesis. The locking member includes a reduced diameter portion with two opposing surfaces that are configured to engage opposing proximal and distal sides of a radially extending member on the elongate member to lock or limit the longitudinal position of the prosthesis on the elongate member during delivery of the prosthesis to a treatment site.

Abstract: A prosthesis delivery system including a prosthesis mounted on an elongate member. The prosthesis has longitudinally offset first and second locking members positioned on the prosthesis. The first and second locking members are configured to engage opposing proximal and distal sides of a radially extending member on the elongate member to lock or limit the longitudinal position of the prosthesis on the elongate member during delivery of the prosthesis to a treatment site.

Abstract: A highly compressible stent is described. The stent includes a plurality of circumferentially offset and interconnected undulating rings having intermediate struts disposed between at least some of the undulating ring struts.

Abstract: A stent delivery system comprising a guide having a retention member configured to exert either an internal force or an external force on the stent to assist in retaining the stent on the guide.

Abstract: A stent delivery system including an elongate member having a proximal segment and a distal segment, the distal segment having a first coil section, a second coil section, an intermediate coil section located between the first and second coil sections and a plastic material overlying one or more of the coil sections.
