1. A stent delivery catheter comprising:

  • an outer tubular member defined by a sidewall and having a proximal end, a distal end, and a guidewire entry port disposed through the sidewall intermediate the proximal and distal ends,wherein a partial circumferential cut in the outer tubular member sidewall defines a distal edge of the guidewire entry port;

    an inner tubular member disposed at least partially inside the outer tubular member and axially movable with respect to the outer tubular member, the inner tubular member having a proximal end, a distal end, and a stent receiving region, the inner tubular member defining a guidewire lumen in communication with the guidewire entry port, the inner tubular member extending distal of the guidewire entry port; and

    an elongate pushing member attached to the inner tubular member and extending proximally through the outer tubular member;

    wherein the pushing member extends across the guidewire entry port from a location distal of the guidewire entry port to a location proximal of the guidewire entry port.
