Abstract
A therapeutic delivery device includes a non-perforated insufflating shaped form, such as a catheter irrigating shaped form, coupled to a first gas source. The insufflating shaped form is sized and dimensioned for positioning within a patient body. A second gas is stored within the insufflating shaped form. The second gas can be stored within an inner chamber of the insufflating shaped form, within the walls of the insufflating shaped form, or the like. In a corresponding method, a first gas reacts with the second gas upon delivery of the first gas from the first gas source through the insufflating shaped form. The reaction forms a gas mixture, which emits from the insufflating shaped form to a targeted location within the patient body. The insufflating shaped form serves to maintain a predetermined concentration of the gas mixture at the targeted location for a desired dwell time.
