Circumferential antenna for an implantable medical device
First Claim
Patent Images
1. A device, comprising:
- an implantable conductive housing for containing electronic circuitry;
a dielectric compartment extending along a surface of the housing;
a wire antenna embedded within the dielectric compartment, wherein the dimensions of the antenna are such that a significant portion of radio-frequency energy delivered to the antenna is emitted as far-field radiation; and
, circuitry within the housing connected to the antenna for transmitting and receiving a modulated radio-frequency carrier.

Abstract
An apparatus and method for enabling far-field radio-frequency communications with an implantable medical device in which an antenna is embedded within a dielectric around the periphery of the device. Such a circumferential antenna saves space while still permitting far-field telemetry over a desired range of frequencies.
