ABSTRACT:
Apparatus and a method for treating an irregularity in a wall of a vessel of a patient defined by an irregular or afflicted wall portion with adjacent normal wall portions comprises a catheter having a distal end portion for being guided through the vessel to the site of the irregularity. A balloon associated with said distal end portion of the catheter for selective inflating to contact the walls of the vessel urges a stent carried by the distal end portion of the catheter in a constricted condition for passage through the vessel into an expanded form with the stent spanning the afflicted wall portion and contacting the adjacent wall portions. The catheter is formed with lumens for inflating the balloon, for receiving a guidewire for guiding the catheter through the vessel, and for connecting a port in the catheter proximate the afflicted wall portion to enable delivery of a therapeutic agent into the vessel to contact the stent and the irregular wall portion.
