    摘要: 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 surf ace 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.

    摘要: Analyte sensor comprises an electrode layer having an elongate body comprising a proximal end and a distal end. The electrode layer includes a first active working electrode area, a second electrode portion, and at least one gap electrically separating the first active working electrode portion and the second electrode portion. The first active working electrode area comprises at least one sensing spot with at least one analyte responsive enzyme disposed thereupon. Additional analyte sensors disclosed.
