Inflatable porous implants and methods for drug delivery
First Claim
1. A graft comprising:
- a graft body section having a proximal end, a distal end, and defining at least one inflatable porous channel;
at least one inflatable porous cuff disposed at the proximal or distal end of the graft body section and in fluid communication with the at least one channel, wherein the at least one inflatable porous cuff is disposed in an axisymmetric cylindrical manner around the proximal or distal end of the graft body section; and
an inflation medium including at least one therapeutic agent configured to be introduced into the inflatable channel;
wherein the inflation medium comprises a curable liquid comprising a therapeutic agent-carrying host polymer.

Abstract
The present invention provides inflatable porous implants, such as grafts, stent-grafts, and bladders, as well as methods and kits for drug delivery. In particular, the grafts and stent-grafts of the present invention provide for the delivery of a therapeutic agent into a flow conduit in the body. The inflatable porous implants provide for direct delivery of larger, more precise dosages of drugs over longer administration periods into the body. Moreover, these inflatable porous implants are often flexible when inserted and have a low profile delivery configuration for easy placement. The implants of the present invention further provide a mechanical or structural function in addition to drug delivery in a single integrated structure.
