LEADLESS PACEMAKER WITH IMPROVED CONDUCTED COMMUNICATION
First Claim
1. A leadless implantable medical device comprising:
- a hermetically sealed housing including a cylindrical body, a first surface at a first capped end of the cylindrical body, and a second surface at a second capped end of the cylindrical body;
a first electrode located at the first capped end and a second electrode located on the second surface, wherein the first and second electrodes include conductive portions configured for contacting one or both of tissue and fluid, and wherein the cylindrical body includes a length and the conductive portions of the first and second electrodes are separated substantially by the length of the cylindrical body;
a therapy circuit configured to deliver stimulating electrical energy using the first and second electrodes; and
a telemetry circuit configured to communicate with a second separate device.

Abstract
A leadless implantable medical device can include a hermetically scaled housing including a cylindrical body, a first surface at a first capped end of the cylindrical body, and a second surface at a second capped end of the cylindrical body. A first electrode can be located at the first capped end and a second electrode can be located on the second surface. The first and second electrodes include conductive portions configured for contacting one or both of tissue and fluid, and wherein the cylindrical body includes a length and the conductive portions of the first and second electrodes are separated substantially by the length of the cylindrical body. The device example also includes a therapy circuit configured to deliver electrical cardiac stimulating energy using the first and second electrodes, and a telemetry circuit configured to communicate with a second separate device.
