Pressure Mediated Selective Delivery Of Therapeutic Substances
Description of Invention:
The present application describes a system and method for improved regional, organ, tissue, tissue-compartment, and celltype-specific delivery of therapeutic agents via infusion of those agents into body lumens under controlled pressure and volume conditions. Methods of varying the pressure and flow rates for given body targets and depths are also disclosed along with methods of determining the proper protocol for a given target tissue. This application also includes designs for access cannulas, catheters, access ports, and other devices for controlled, targeted delivery of therapeutic agents, including drugs and gene therapy vectors. Local administration of drugs, gene therapy vectors, and other therapeutic agents in accordance with this invention can permit organ, tissue, tissue-compartment, and celltype-specific delivery, thereby maximizing administration to intended tissue targets using therapeutically effective dosages while simultaneously reducing the risk of systemic delivery and toxicity.
