Disclosed is a self-test device and method for assessing the functional performance of a reader device that is configured to interface with a wireless sensor. The self-test device may be configured to analyze the accuracy of a signal transmitted from the reader device or the accuracy of a signal received by the reader device. In one embodiment, the reader device may be configured to engage the self-test device to allow the reader to transmit a signal, such as a short pulse of energy or a short burst of radio frequency energy to cause the self-test device to output a resonant signal. The self-test device may receive the transmit signal from the reader and evaluate it against predetermined values. The evaluated signals may be used to assess the accuracy of the transmit signal of the reader device to identify potential calibration issues and initiate remedial action by an automated system or human intervention if needed. The self-test device may be built into a docking station where the reader is placed when not in use.

A microwave ablation system and method is disclosed comprising a balloon catheter apparatus and a control system. The balloon catheter apparatus comprises a catheter configured to house a coaxial cable and one or more coolant channels, an inflatable balloon located at the distal end of the catheter, and an antenna positioned in the inflatable balloon and in communication with the coaxial cable. The control system comprises a fluid pump configured to introduce fluid into a proximal end of the catheter, a power amplifier capable of generating microwave energy for delivery to the target tissue zone for at least one energy application cycle ranging from 60 seconds to 600 seconds at a frequency ranging from 2.4 GHz to 2.5 GHz, and a computer system configured to monitor and/or regulate the delivery of microwave energy to the target tissue, the fluid pump, at least one sensor, and antenna reflected power.

This invention provides a novel electronically tunable active duplexer for wireless transceiver applications. It relates to an active duplexer with full-duplex operation, permitting simultaneous transmission and reception of signals at same or different frequencies. Instead of incorporating fixed or mechanically adjustable capacitors, and even instead of incorporating varactor diodes, it incorporates one or more capacitance tuning circuit in phase shifting networks enabling one to electronically tune, with ease and precision, the frequency at which isolation is desired, over a band in both transmit and receive modes of operations.
