Abstract:
1. A rapid exchange type catheter adapted for placing a self-expanding stent, the catheter comprising: an outer member having a proximal portion, a distal portion, and a guidewire port therebetween, the distal portion adapted to cover a self-expanding stent, an inner member having a proximal portion and a distal portion, the distal portion including a guidewire channel for passing a guidewire, the distal portion adapted to receive a self-expanding stent thereon, wherein the inner member is longitudinally displaceable with respect to the outer member for deploying a stent; and a mandrel member having a distal end and a proximal end, wherein the distal end has a ramp, the proximal end is coupled to the proximal portion of the outer member so as to prevent longitudinal displacement of the mandrel with respect to the outer member when the inner member is longitudinally displaced with respect to the outer member for deploying a stent.
