Wireless Medical Telemetry

Wireless medical telemetry helps monitor patient physiological parameters over a distance via RF communications between a transmitter worn by the patient and a central monitoring station. These 

CDRH receives many inquiries from healthcare organizations, medical device manufacturers, clinicians, and the public seeking information about experiences with and prevention of electromagnetic interference (EMI) with medical devices. The following information is intended to help minimize the risks associated with medical device EMI and promote electromagnetic compatibility (EMC) in healthcare facilities. Some recommendations for healthcare facilities to follow include 

Making use of available resources such as EMC professionals and publications and Internet web pages on the subject of medical device EMC 

Assessing the electromagnetic environment of the facility and identifying critical medical device use areas 

Managing the electromagnetic environment, RF transmitters, and all electrical and electronic equipment, including medical devices, to reduce the risk of medical device EMI and achieve EMC 

Coordinating the purchase, installation, service, and management of all electrical and electronic equipment used in the facility to achieve EMC

This book. Implantable Neural Prostheses 2 Techniques and Engineering Approaches, is part two of a two-volume sequence that describes state-of-the-art advances in techniques associated with implantable neural prosthetic devices. The techniques covered include biocompatibility and biostability, hermetic packaging, electrochemical techniques for neural stimulation applications, novel electrode materials and testing, thin-film flexible microelectrode arrays, in situ characterization of microelectrode arrays, chip-size thin-film device encapsulation, microchip-embedded capacitors and microelectronics for recording, stimulation, and wireless telemetry. The design process in the development of medical devices is also discussed.
