Implantable medical device with fractal antenna
First Claim
1. A device, comprising:
- a header coupled to an implantable housing, the housing having an electronic circuit configured to communicate via a modulated radio frequency carrier; and
an antenna, at least a portion of the antenna disposed within, on, or adjacent the header and coupled to the electronic circuit,the antenna including at least one conductive segment forming at least one first selected pattern, wherein the at least one first selected pattern is defined by a plurality of second selected patterns, and wherein the second selected patterns are smaller versions of the at least one first selected pattern.

Abstract
An apparatus and method for enabling an implanted fractal antenna for radio frequency communications between an implantable medical device and an external device. The fractal antenna may be disposed within or outside of a header assembly of the device housing. Various examples include a three dimensional patterned cylinder usable as a tissue anchor or stent. In another embodiment the antenna may be cast, molded, stamped, punched, milled, laser cut, etched or other methods to form a fractal pattern in conductive media. In another embodiment the antenna may be formed of a printed circuit board (PCB) either with or without an included ground reference plane. In another embodiment the antenna may be formed in a fractal pattern and then wrapped around a part of the implantable device.
