Ottawa, Canada, May 25, 2004 -- Zarlink Semiconductor today announced that Given Imaging Ltd., maker of the world's only swallowable camera capsule for diagnosing disease of the gastrointestinal tract, is now using an ultra low-power transmitter chip from Zarlink in its M2A capsule endoscope.
The defining characteristic of Zarlink's custom RF (radio frequency) transmitter -- its miniscule power consumption -assures the operating life and image capabilities of the camera capsule as it passes through a patient's esophagus, stomach and small intestine.
The M2A capsule - consisting of a microchip camera, light-emitting diodes that act as a flash, Zarlink's RF transmitter chip, antenna and two silver-oxide batteries -is swallowed by the patient and then passes naturally through the digestive tract. The camera's images are relayed by the RF transmitter to a data recorder in a belt worn by the patient, who is free to continue with normal daily activities throughout the exam.
Data is then downloaded to a workstation equipped with proprietary image processing software, and a video of the gastrointestinal tract is produced revealing pathologies and diseases of the small intestine that were previously undetected by traditional diagnostic tools.

Published medical articles conclude that capsule endoscopy has a higher diagnostic yield than traditional, invasive methods in diagnosing patients with gastrointestinal disorders of the small intestine, including Crohn's Disease and small bowel cancer. Given Imaging's capsule endoscopy technique has already been used to diagnose thousands of patients in the USA, Canada, Europe, Asia and Australia.
Ultra-low power and wireless technology - a powerful combination
Zarlink regards its RF transmitter as a "breakout" product - the first in a range of new devices combining the company's ultra-low power and wireless technologies.
Zarlink is a leading supplier of highly reliable, ultra low-power ICs that consume minimal battery power, extending the operating life of healthcare devices such as hearing aids and pacemakers. The company also designs low-power RF chips for wireless devices, including cell phones.
"We're combining our ultra low-power and wireless technologies to design new chips for the healthcare and communications markets," said Steve Swift, Vice President and General Manager, Ultra Low-Power Communications, Zarlink Semiconductor. "To advance the capabilities of emerging medical practices, such as the Given Imaging system, these ultra low-power devices satisfy challenging low-power and high-performance specifications, and meet very strict qualification and standards requirements. In the consumer marketplace, there is a rising demand for ultra low-power RF technologies as completely connected, battery-powered communications networks in the home and office become commonplace."
