Patent ID: 8460239

Claim:
A rapid exchange type stent delivery catheter comprising: an outer tubular member having a proximal end, a distal end, and a guidewire entry port positioned closer to the distal end than the proximal end; an inner tubular member positioned at least partially inside a lumen defined by the outer tubular member, the inner tubular member extending distally from a location distal of the guidewire entry port and defining a guidewire lumen in communication with the guidewire entry port; and an elongate pushing member attached to the inner tubular member and extending proximally from a location distal of the guidewire entry port to a location proximal of the proximal end of the outer tubular member; wherein the inner tubular member and the outer tubular member are axially movable with respect to one another, wherein distal movement of the outer tubular member is limited by a distal end surface of the inner tubular member and proximal movement of the inner tubular member is limited by a distal end surface of the outer tubular member; wherein the outer tubular member comprises a proximal section including a hypotube having an outer diameter and a distal section comprising a distal tubular member having an outer diameter that is larger than the outer diameter of the hypotube; further comprising an intermediate tubular member, wherein a portion of the distal tubular member is crimped down to the intermediate tubular member and a portion of the elongate pushing member extends through the intermediate tubular member.
