Abstract
A self-expanding stent delivery system for medical treatment of a patient has a rapid exchange configuration. The system includes a stent, a proximal and distal shaft section, a cartridge for holding the stent compressed until deployment, a stabilizer for holding the stent in position as an outer sheath is retracted, and a flexible tapered introducer tip. The stent is mounted about the distal shaft section and compressed to an initial diameter within the cartridge. The introducer tip is affixed to the distal end of the catheter system. A guidewire may be back-loaded into a distal port at the catheter system distal end. The guidewire extends through a guidewire tube through the location of the stent, and escapes through a proximal guidewire port, which is located at a point intermediate the catheter system proximal and distal ends.
