Antenna for an implantable medical device
First Claim
1. An apparatus comprising:
- a housing that includes;
a telemetry module; and
an inner conductive feed loop that is electrically coupled to the telemetry module, wherein at least a portion of the inner conductive feed loop forms a portion of an antenna; and
a fixation mechanism located outside the housing and mechanically coupled to the housing, and configured to affix the apparatus to a target location, wherein at least a portion of the fixation mechanism forms a radiating portion of the antenna, the fixation mechanism being magnetically coupled through the housing to the conductive feed loop to obtain the communication signals to be transmitted by the telemetry module and radiate the signals from the telemetry module to another device.

Abstract
This disclosure describes antenna structures for use in an implantable medical device. The implantable medical device may include a housing that hermetically encloses electronic components of the implantable medical device and a fixation mechanism that affixes the implantable medical device to a target location, such as a wall of a vessel. The fixation mechanism functions as a radiating element of an antenna of the implantable medical device. The housing of the implantable medical device may include a conductive loop that electrically couples to a telemetry module and magnetically couples to the fixation mechanism. The telemetry module may provide signals to be transmitted to the inner loop and those signals are magnetically coupled between the inner loop and the fixation mechanism, which radiates the signals.
