MEDICAL DEVICE ANTENNA SYSTEMS HAVING EXTERNAL ANTENNA CONFIGURATIONS
First Claim
1. A medical device having wireless communication capability for data transfer with a host device, the medical device comprising:
- a processor configured to control at least one function of the medical device;
a wireless communication module configured to communicate at a first frequency, the communication module being in operational data connection with the processor;
a case enclosing the processor and the wireless communication module, the case having an outer surface and defining an inside space within which the processor and wireless communication module are located, and an outside space within which the outside of the case and surrounding areas and objects are located, the outer surface of the case residing in the outside space;
an antenna located entirely in the outside space, the antenna being configured to efficiently communicate at the first frequency; and
an antenna feed interconnecting the antenna with the wireless communication module;
whereby the antenna provides a transducer for wireless data communication between the processor and a host device.

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.
