Patent ID: 8628633

Claim:
A method of manufacturing a catheter for the uniform delivery of fluid throughout an anatomical region, comprising the steps of: forming an elongated support comprising interruptions on a surface of said support which terminate in outer edges; configuring said support and interruptions so that when a porous membrane is wrapped around said support one or more lumens are formed between said support and said porous membrane; wrapping said porous membrane around said support to form said catheter such that a plurality of lumens are formed between said support and said membrane; and affixing porous membrane to the outer edges of the interruptions with an adhesive, wherein the porous membrane comprises a radially homogenous sponge-like, foam-like or hollow fiber material that becomes saturated with a fluid introduced within the plurality of lumens and has substantially uniform dispensation of fluid along the porous membrane; wherein the plurality of lumens are fluidly independent from one another such that the plurality of lumens communicate with one another; and wherein said membrane forms a portion of a wall of each of said plurality of lumens when wrapped around the outer edges of the interruptions.
