Abstract
A stent delivery system includes a catheter having a balloon mounted at its distal end for advancement into and withdrawal from a patient's vascular system by manipulation of the catheter from a point external to the patient's body, a lumen extending through the catheter into the balloon to allow the balloon to be selectively inflated and deflated from a pressurizing medium external to the patient's body, and spaced-apart radiopaque projections on the catheter adjacent the proximal and distal ends of the balloon to receive and retain a stent therebetween in overlying relation to the balloon and to provide x-ray markers thereof. The stent is deployed at a designated target site by selectively inflating the balloon to radially expand the diameter of the stent against the vascular wall. The projections are shaped (i) to protect the stent from being dislodged during travel through the vessel, but not to interfere with radial expansion of the stent during balloon inflation and (ii) to avoid injury to tissue of the vascular wall during movement of the catheter through the vessel. A method of fabricating such a stent delivery system includes providing a catheter with an elongate flexible …
