Stent and therapeutic delivery system
First Claim
1. A stent assembly for deployment within a patient'"'"'s body comprising:
- A. frame means for defining the form of the assembly;
B. means supported by said frame means for defining a therapeutic agent reservoir and for enabling the seepage of a therapeutic agent in the therapeutic agent reservoir therefrom; and
C. port means connecting with said reservoir means for introducing a therapeutic agent into said therapeutic agent reservoir subsequent to deployment of the stent assembly in a patient'"'"'s body.

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.

24. A therapeutic agent delivery system for replenishing a reservoir of a replenishable stent comprising:
-
A. insertion means having a distal end for inserting within the body of a patient and a proximal end for control by an operator of said insertion means; B. transfer means proximate the distal end of said insertion means for connecting with the reservoir; C. lumen means in said insertion means for connecting said transfer means with the proximal end of said insertion means; and D. means associated with the proximal end of said insertion means for urging a therapeutic agent through said lumen means and transfer means to enable thereby replenishment of the reservoir of the replenishable stent. - View Dependent Claims (25, 26)
