Folded antennas for implantable medical devices
First Claim
1. An apparatus, comprising:
- an implantable medical device comprising;
a housing;
an implantable telemetry circuit carried within the housing;
a dielectric compartment, mechanically coupled to the housing, the dielectric compartment including at least a first face portion on a first sidewall of the dielectric compartment, and a second face portion;
an implantable telemetry antenna, located at least partially within the dielectric compartment;
wherein the implantable telemetry circuit is electrically coupled to the implantable telemetry antenna and configured to wirelessly transfer information electromagnetically using the implantable telemetry antenna; and
wherein the implantable telemetry antenna has a first antenna portion extending along and conforming to contours of the first face portion of the dielectric compartment, and a second antenna portion extending along and conforming to contours of the second face portion of the dielectric compartment, the implantable telemetry antenna including a spiral conductor portion that extends from the first antenna portion into the second antenna portion, around a first bend or corner in the second portion and back into the first portion, and around a second bend or corner in the first portion and back into the second portion.

Abstract
In an example, an apparatus can include an implantable medical device comprising a housing, an implantable telemetry circuit carried within the housing, a dielectric compartment mechanically coupled to the housing, the dielectric compartment including first and second substantially parallel face portions and a third face portion extending between the first and second face portions, and an implantable telemetry antenna, located at least partially within the dielectric compartment. The implantable telemetry circuit can be electrically coupled to the implantable telemetry antenna and configured to wirelessly transfer information electromagnetically using the implantable telemetry antenna. In an example the implantable telemetry antenna comprises a spiral conductor portion extending along the first, second, and third face portions. In an example the spiral conductor includes a cross section having a lateral width that can be greater than a sidewall height of the cross section.
