ABSTRACT:
A catheter system comprising of a catheter sheath and a multichamber balloon catheter capable of simultaneous or sequential delivery of substances such as drugs, anesthetics, biologicals or wound modulating agents into an organ or tissue remote from the point of entry of the catheter system. A specific use of such catheter system is for the timed application of wound modulating agents prior to the formation of a fistula in the filtration procedure used for the management of glaucoma. Another use is for the application and subsequent washing of the scar formation with wound modulating agents after an unsuccessful glaucoma filtration procedure. Substances requiring controlled release is applied through one lumen of the balloon catheter whose exit port is covered with a semipermeable or microporous membrane. Other substances not requiring controlled or slow release is applied through a second lumen where the substance can exit freely through a hole at one end of the second lumen. Retrieval of applied substances is also possible through gentle suction from the second lumen or a third lumen if needed.
