Telemetry antennas for medical devices and medical devices including telemetry antennas
First Claim
1. A medical device, comprising:
- a housing including a mating surface having a feed-through opening;
telemetry circuitry within the housing;
a header mechanically affixed to the mating surface of the housing;
one or more connectors within the header that is/are configured to receive a proximal end of one or more leads; and
an antenna within the header;
wherein the antenna is electrically connected to the telemetry circuitry within the housing;
wherein the antenna spirals about a central axis and has a rectangular cuboid circumferential shape; and
wherein the central axis, about which the antenna spirals, is perpendicular to the mating surface of the housing.

Abstract
In an embodiment, an antenna for a medical device, e.g., an implantable medical device (IMD), comprises an electrically conductive wire that spirals to form a three-dimensional shape of a rectangular cuboid. In another embodiment, the antenna comprises an electrically conductive wire that spirals to form a three-dimensional shape of an elliptical cylinder, an oval cylinder, an elongated pentagonal prism, an elongated hexagonal prism, or some other shape where the longitudinal diameter of the antenna is greater than the lateral diameter of the antenna. The antennas are sized to fit within a portion of a header of the medical device. Such antennas are designed to provide increased antenna gain and antenna bandwidth.
