Abstract
Devices for measuring and communicating physiological data are described. An implanted biocompatible sensor may be utilized to wirelessly communicate with an external transceiver. The biocompatible sensor may include a tubular body, one or more biomedical sensing elements coupled with the tubular body, and a microprocessor in electronic communication with the one or more biomedical sensing elements. The biocompatible sensor may also include an antenna coupled with the tubular body. The transceiver may be in electronic communication with the microprocessor via the antenna and may be configured to power the microprocessor using inductive radio frequency energy.

A biocompatible sensor, comprising:
- an elongate tubular body configured for insertion in a body lumen and comprising a sensor lumen extending from an open proximal end to an open distal end;
- one or more biomedical sensory elements coupled with the tubular body and configured to measure a characteristic of a fluid flowing through the sensor lumen;
- a microprocessor in electronic communication with the one or more biomedical sensory elements;
- and
- an antenna coupled with an outer surface of the tubular body and configured to receive inductive radio frequency energy to power the microprocessor.
