Abstract
An inflatable medical device for the delivery of medications to an organ in the body including a catheter having a plurality of lumens (13, 22, 28) disposed therein. The distal end of the catheter is adapted to be disposed within a bodily organ. A hollow, inflatable, medication-deliverable balloon (16) is disposed on the distal end of the catheter and the interior of the balloon (16) is in fluid flow relationship with one of the lumens (22) to enable the balloon (16) to be inflated. An array of conduits (40) is disposed within the walls of the balloon for the delivery of medications to predetermined locations within said bodily organ. Another lumen (28) in the catheter shaft (14) is provided to deliver medications to the conduits (40) in the wall of the balloon (16). An egress (17) for the medications is provided so that they may be dispensed at the site being treated.
