Medical device antenna systems having external antenna configurations
First Claim
1. A system for mounting a medical device comprising a primary antenna and a secondary antenna at or near the skin of a user, the system comprising:
- a mounting having an adhesive surface configured to adhere to the skin of the user;
a thin film substrate coupled with the mounting and having a thin film substrate surface;
a printed conductive layer on the thin film substrate surface, wherein the secondary antenna is disposed within the printed conductive layer;
a transmitter housing comprising electronic components, the primary antenna, and a printed circuit board, wherein the transmitter housing is coupled with the thin film substrate; and
a sensor configured to sense a physiological parameter and provide sensor data to the electronic components.

Abstract
A medical device includes an antenna external to a case, package, or encapsulant for the electronic systems of the medical device. In one embodiment, a diabetes infusion pump is enclosed within a metal case, the pump including a processor and a communication module for wireless communications. An antenna is disposed in the delivery tubing of the pump outside the case with an antenna feed interconnecting the external antenna with the internal communication module. In another aspect, a thin film antenna is formed on the outer surface of the case in which a physiological parameter sensor, such as a glucose sensor, is enclosed. Multiple antennas may be used for communications on different frequencies.
