Embodiment Construction

[0017] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings. However, this invention may be embodied in many different forms, and therefore should not be construed as limited to the embodiments set forth herein; rather, these embodiments are intended to be thorough and complete and limit the scope of the invention. fully communicated to those skilled in the art. The terminology used in the detailed description of the embodiments illustrated in the drawings is not intended to limit the invention.

[0018] One aspect of the invention relates to how the body responds to foreign objects of different sizes. Generally, the body can respond to a perceived foreign object in two ways. If the foreign object is large, the body tries to keep the foreign object away from the body by wrapping it in scar tissue. This occurs along with an inflammatory reaction on the surface of the foreign body that creates the scar wrap. If t...

Abstract

The present invention generally relates to the use of small particles, such as micro particles or nanoparticles, to produce a therapeutic scar such as ''trans-mural'' scarring or other desired ''deep tissue'' scarring. In one preferred embodiment, these particles can be delivered to a target location by an implant. More specifically, these particles can be incorporated into the structure of implants or into the coatings on implants. In another preferred embodiment, these small particles can be delivered directly with a catheter by electrophoresis or hydraulic pressure.
