I still have not found the JMAR connection to this English/ Israeli endoscope. Below is an interesting Reuters release. Any leads? John Wilson
Wireless Endoscope Can Be Swallowed Like a Pill
LONDON, May 25 (Reuters) - A disposable, capsule-sized video camera has given British and Israeli researchers a new way to detect stomach and bowel problems that avoids the need for rectal examination.
"This is completely painless. Patients just swallow the capsule. They don't know it is there. The other thing that is different is that they don't have to be in a hospital environment," Dr. Paul Swain, of the Royal London Hospital, said in a telephone interview with Reuters.
The torpedo-shaped endoscope, devised by Dr. Swain and his Israeli colleagues at Given Imaging Ltd in Yoqneam, Israel, measures just 11 mm by 30 mm (0.4 in by 1.2 in). It can be swallowed like a pill, and it takes images of the stomach and upper small bowel as it passes unaided through them.
Unlike an endoscope, the device has no painful external wires or fibreoptic bundles or cables. It contains a tiny light source, radio transmitter and video camera lens that transmit images stored digitally on a portable receiver worn on a belt.
After the endoscope passes through the body the patient hands the belt back to the physician and the images are downloaded onto a screen. The device is disposable and is contained in a sterile pack, so the chance that it could transmit an infection to patients is considered to be much lower than that with a normal endoscope.
"Patients are much freer during it and can do their normal daily activities. The other advantage is that it shows really well a part of the bowel we have not been able to image properly before ? the small bowel," Dr. Swain said.
The endoscope, which is described in the May 25th issue of Nature, allows 6 hours of continuous recordings. It takes about 24 hours to pass through the body. Its position is calculated from the strength of the signal, and patients are not even aware of it.
Initially the researchers foresee using the device to detect bleeding after surgery from sites that cannot be reached with a normal endoscope. It can also be used to detect bowel or stomach cancer.
Dr. Swain and his colleagues have already tested the endoscope on 10 people with good results. Patients had no trouble swallowing it and felt no discomfort while it transmitted the video images.
The researchers have not determined a price for the instrument, but they said that it would be quite cheap to make. An Israeli company is working on it, but it must be approved by regulatory authorities before it will be commercially available.
