What if there were a technology that could make people with type 1 diabetes feel absolutely wonderful, completely healthy, better than they ever realized was possible? And what if it were about to disappear? Well, there is such a technology, and it is in serious jeopardy. It's called the implantable insulin pump, currently made by Medtronic. This is the story of four people who have been using this device for 20 years, and their desperate crusade to keep it from disappearing forever.
University of Florida engineers have designed and tested versions of a sensor for applications ranging from monitoring diabetics' glucose levels via their breath to detecting possible indicators of breast cancer in saliva. They say early results are promising - particularly considering that the sensor can be mass-produced inexpensively with technology already widely used for making chips in cell phones and other devices.
Two new meters that purport to measure your blood glucose without a fingerstick are currently in the works–again. The road to a non-invasive meter is one that many have traveled before, but no one, thus far, has ever reached the market.
GlucoLight's continuous, non-invasive device is a novel approach to glucose monitoring in the acute care environment. Using optical coherence tomography (OCT), the device is able to measure blood glucose levels through a unique anatomical area in the skin that shows physiological changes that directly correlate to changes in blood glucose. The GlucoLight monitor displays real time glucose measurements with an initial single point calibration.
The race is on! Since 1986, the contestants—more than 100 start-up biotech companies—have been competing for the prize: a chunk of the billion-dollar market that awaits the manufacturer of a reliable, FDA-approved, noninvasive glucose monitor.
As a diabetes researcher, exercise physiologist and individual with type 1 diabetes, I am always curious about how the latest diabetes technology fits into an exercise program. Exercise is, after all, one of the three cornerstones of diabetes management, along with diet and medication.
Someday, you could get your insulin by slapping a patch on your skin and activating delivery with an ultrasonic device, say researchers in Pennsylvania, who posted a paper on the subject at the American Diabetes Association's scientific sessions in June.
For the first time, near-infrared spectroscopy (NIRS) has demonstrated a capability to accurately measure glucose levels. The device uses fiber optics to illuminate vascular tissue. A tungsten-halogen light is connected to the fiber optic bundle; this is directed at the subject's thumb. Glucose has its own special "spectral signature" which can be differentiated from other molecules in the tissue. The device then processes this information (which is both reflected and absorbed by the fiber optic light) using a mathematical algorithm to come up with an accurate plasma glucose level.
Biocontrol, one of many hopeful developers of a noninvasive glucose monitoring device, will link with the Joslin Diabetes Center in Boston. Joslin researchers will conduct clinicals trials for approval of Biocontrol's Diasensor 2000, a device that measures glucose levels with spectroscopy (technology using infrared light).
Could there be more than beauty in the eye of the beholder? How about an accurate blood glucose reading? That's what Visionary Medical Products Corporation (VMPC) in Carson City, Nevada, is hoping for - a noninvasive test that will determine BG levels through minute blood vessel changes in the retina.
Several companies are actively working on technologies to improve blood sugar testing and thereby capture a share of the two- to three-billion dollar blood sugar testing market. The goal is to make testing easier, more convenient and, the hope of many, continuous without sticking the finger. Here are some of the companies trying to become the first to offer improved testing and how they plan to do it:
In November, President Clinton signed the "Food and Drug Modernization Act of 1997," a new law intended to streamline the regulatory process and improve the regulation of medical devices. One section of the law specifically advocates Congress to encourage the development of safe and effective noninvasive blood glucose meters.
Glucose monitors have come a long way since the hulking, brick-sized meters of the seventies. Now, new technology has created smaller and lighter monitors the size of pagers. However, people with diabetes everywhere are still feeling the pain of testing. When will painful finger pokes no longer be necessary?
Twenty First Century Health Inc., a new products development company, has announced their acquisition of the exclusive rights from Milton Fuller and Solid State Farms to develop a non-invasive monitor that measures hemoglobin A1c.
Almost immediately after complaining to a congressional subcommittee that it was unfairly treated by the FDA during its first 510(k) submission, Biocontrol Technology, Inc. announced that it submitted a new revised 510(k) pre-market notification for its Diasensor 1000 non-invasive glucose sensor.
Biocontrol Technology, Inc. has been receiving a great deal of attention regarding its Diasensor 1000 non-invasive blood glucose meter. Stockholders have been calling the (DIABETES HEALTH) office asking if we know what is going on with Biocontrol-when will the device be ready to market?
Why would patients veto a device that can monitor glucose levels without the need for blood? Because they had to put the device in their ear. Though technically non-invasive, focus groups found the process unappealing.
As clearly demonstrated by the DCCT, blood glucose monitoring is a critical element in the maintenance of normal blood glucose levels. Cygnus Therapeutic Corporation in Redwood City, California is working on a new non-invasive glucose monitoring system that could dramatically change the way people with diabetes monitor their glucose levels. Unlike the current procedure, which measures the level of glucose in the blood based on blood samples drawn from the fingertips, the new system is non-invasive, and utilizes interstitial fluid rather than blood.
Biocontrol Technology Inc. of Pennsylvania will give away its first non-invasive blood glucose sensor to the Juvenile Diabetes Foundation (JDF) for a charity auction. The sensor will be awarded to the highest bidder, with all proceeds going to the JDF. Biocontrol Technology plans to file a 510K application with the Food and Drug Administration soon, and hopes the new sensor will be available in the Spring of 1994.
I'm sure you've heard about the non-invasive blood glucose sensors that everyone in the diabetic meter business is talking about; it is, after all, big news. The ability to take accurate glucose readings without the traditional finger-stick would be a blessing to people with diabetes. The estimated $500 million prize going to the inventor of such a device would be a blessing to whichever company produces the first one. The obstacles involved, however, insure that whoever wins it will have to work long and hard.
INDIANA, PA. - September 2, 1992 - Biocontrol Technology, Inc. (NASDAQ:BICO) announced today that it has entered into a lease agreement with the Indiana County Board of Commissioners within the Indiana County Commerce Center for 22,500 square feet for the purpose of manufacturing their non-invasive glucose sensor.
