Medical device for delivering patches
First Claim
1. A medical device for treating body tissue of a patient comprising:
- (a) an elongated member having a proximal end and a distal end;
(b) an expandable assembly disposed at the distal end of the elongated member, wherein the expandable assembly is capable of changing from a retracted position to an expanded position and the expandable assembly comprises a plurality of wire elements and wherein each wire element has a first end and a second end; and
(c) a patch having two opposing surfaces;
wherein one of the opposing surfaces comprises an adhesive material and a biologically active material;
wherein the other opposing surface is disposed upon at least one of the wire elements, and wherein the wire elements are arranged in a basket-like configuration when the expandable assembly is in the expanded position and wherein both ends of at least one wire element is connected to the distal end of the elongated member.

Abstract
The present invention relates to a medical device and method for treating the body tissue of a patient. The present invention is also directed to a method of making the medical device and a method of using the medical device. More particularly, the invention relates to a medical device which is inserted into the body for delivery of therapeutic patches to the surface of a body lumen, organ or cavity. Specifically, the medical device has an umbrella-like or a basket-like expandable assembly; and a therapeutic patch. The expandable assembly is capable of changing from a retracted position to an expanded position. The expandable assembly can be self-expanding or non-self-expanding. In one embodiment, the medical device comprises an elongated member; an umbrella-like expandable assembly which has a plurality of wire elements; and a therapeutic patch. The therapeutic patch comprises a sheet having two opposing surfaces wherein one of the surface comprises an adhesive material and at least one biologically active material.
