Method for ablating tissue to facilitate implantation and apparatus and kit for use therewith

Abstract: A method for treating a mammalian body having tissue comprising creating a cavity in the tissue formed by an internal surface of the tissue. The internal surface is ablated. An implant-forming material is introduced into the cavity to create an implant in the tissue. The ablation of the internal surface inhibits migration of the implant. An apparatus and kit for use with the method are provided. (end of abstract)

CROSS-REFERENCE TO RELATED APPLICATION

The application claims priority to U.S. provisional patent application No. 60/959,441 filed on Jul. 13, 2007, the entire content of which is incorporated herein by this reference.

SCOPE OF THE INVENTION

The present invention relates to methods and devices for treating a mammalian body and more particularly to methods and devices for creating implants in tissue of a mammalian body.

BACKGROUND

Medical devices have been provided for the delivery of a material to various portions of a wall forming a vessel such as the gastrointestinal tract of a mammalian body to create implants in the wall. See, for example, U.S. Pat. No. 6,251,063. There remains, however, a need for inhibiting migration of such implants in the wall.

SUMMARY OF THE INVENTION

A method for treating a mammalian body having tissue comprising creating a cavity in the tissue formed by an internal surface of the tissue is provided. The internal surface is ablated. An implant-forming material is introduced into the cavity to create an implant in the tissue. The ablation of the internal surface inhibits migration of the implant. An apparatus and kit for use with the method are provided.
