Embodiment Construction

[0061] The basic components of one embodiment of a multi-balloon catheter system according to the invention are shown in figure 1middle. As used in this description, the terms "top", "bottom", "above", "under", "above", "under", " above", "under", "on top", "under", "upper", "under", "upper", "lower", "front", "rear" , "forward" and "rearward" refer to objects when they are in the orientation shown in the figures, and such orientation is not required for the purposes of the present invention.

[0062] Such as figure 1 As shown, a multi-balloon catheter system (20) includes a catheter (22) and a fluid source (24). Conduit (22) may have any suitable diameter and length depending on the particular application, and may be flexible, rigid, or semi-rigid. The catheter (22) can be made of any commercially available material, such as polyethylene, that is sufficiently flexible to allow the shaft to be safely inserted through the available opening of the body lumen so that it bends...

Abstract

A multi-balloon catheter system is provided including a catheter (22,122,222) having a first balloon (32,132,232), a second balloon (34,134,234) and a third balloon (36,136,236), and a fluid source (20) that inflates the first and second balloons by supplying fluid thereto to create a chamber (58,158), wherein the catheter includes a fluid pathway for delivering the agent, and the fluid source increases fluid pressure within the chamber by supplying fluid to the third balloon such that the agent is extravasated into tissue.

Description

technical field [0001] The present invention relates to methods and systems for delivering therapeutic and diagnostic agents to specific cellular locations located in and near body tissues and body cavities. More specifically, the present invention relates to a system and method for the extravasation of diagnostic and / or therapeutic agents to body tissues and body cavities via a multi-balloon catheter that facilitates extravasation of the agent into In the cell membranes and structural walls of body cavities. Background technique [0002] When diagnosing and treating diseases of various body cavities and organs, it is necessary to deliver diagnostic and / or therapeutic agents to organs at specified locations. The most commonly used drug delivery routes include non-invasive oral delivery (delivery through the mouth), topical delivery (dermal), transmucosal delivery (via nasal, buccal / sublingual, vaginal, ophthalmic, and rectal) and inhalation routes. However, many therapeuti...
