Apparatus and method for monitoring a condition inside a body cavity

摘要

An apparatus (10) utilizes microelectricalmechanical systems (MEMS) technology to monitor a condition in a body cavity (28). The apparatus (10) comprises at least one sensor (42) for insertion into the body cavity. The sensor (42) generates a signal in response to a condition inside the body cavity (28). At least one telemetric device (44) is operatively coupled with the sensor (42). The telemetric device (44) is operable to receive the signal from the sensor (42) and to transmit an electromagnetic signal dependent upon the signal. The telemetric device (44) includes at least one coil member (82) extending from the telemetric device. The coil member (82) engages the body cavity (28) to secure the telemetric device (44) in the body cavity.
