Abstract

An apparatus for delivering a therapeutic and / or diagnostic agent to tissue within a bodily cavity is provided herein. The apparatus may include a catheter assembly including a catheter and a delivery balloon having an expandable material disposed thereon, wherein the expandable material may be an absorbent at least partially charged with a therapeutic and / or diagnostic agent. The method may include allowing the delivery balloon to expand by supplying fluid to the delivery balloon until the expandable material adopts expanding state of the expandable maerial contact tissue and is implanted into a body cavity to deliver the therapeutic and / or diagnostic agent to tissue.

Description

technical field [0001] The present invention relates to methods and systems for delivering therapeutic and / or diagnostic agents into and near body tissues and cavities. More specifically, the present invention relates to methods and systems for delivering diagnostic and / or therapeutic agents to body tissue and body cavities via a balloon catheter upon which an expandable absorbent or stent is placed, the expandable absorbent or stent filled with Therapeutic and / or diagnostic reagents. Background technique [0002] In the diagnosis and treatment of diseases of various body cavities and organs, there is a need to deliver diagnostic and / or therapeutic agents to specific locations in the organ. The most common modes of administration include non-invasive oral (oral); topical (transdermal); transmucosal (nasal, buccal / sublingual, vaginal, ocular, and rectal). In general, however, many therapeutic and diagnostic agents may not be administered in these ways because they would be ...
