Abstract

A therapeutic agent delivery system includes an irrigating shaped form, such as a non-perforated irrigating shaped form, fluidly coupled with a container storing a first agent. The irrigating shaped form is sized and dimensioned for positioning within a patient's body. A second agent is disposed at the irrigating shaped form. The second agent can either be supplied separately to the irrigating shaped form, pre-exist within the irrigating shaped form, exist as a coating or other residual element on the irrigating shaped form, or the like. The irrigating shaped form is expanded to maximum predetermined diameter and pressed against a targeted location within a patient's body. In a corresponding method, upon delivery of a first agent from the first agent container through the irrigating shaped form, the first agent reacts with the second agent forming a therapeutic agent, which can be pressurized. The therapeutic agent emits from a portion of the irrigating shaped form at the targeted location. The irrigating shaped form serves to maintain a predetermined pressure and concentration of the therapeutic agent at the targeted location for a desired dwell time.
