A Decade of Development for SMSI: Will it lead to Improved Accuracy in CGM?

The mission of ten-year old company Sensors for Medicine & Science is to develop a sensor that would obviate the need for patients with diabetes to extract blood or fluid samples for testing. Implanted under the skin, the SMSI sensor is continuously immersed in interstitial fluid containing glucose and provides frequent glucose readings. It thus has the potential to become the cornerstone of a new continuous glucose monitoring (CGM) system, one that works very differently than the early-generation systems on the market today. Part of a group of articles that includes: "Where are They Now? Checking in on Three Glucose Monitoring Companies," "Pelikan Swoops in on the Big Four" and "GlucoLight: Making Non-Invasive Glucose Monitoring Real."

In the medical device industry, products that undergo years of development can face the risk of being obsolete before they ever see the light of day. Device companies have succumbed to that pitfall in heart failure, where complex artificial hearts and ventricular assist devices that didn’t make it to the market after decades of research are already being supplanted by much simpler partial support devices, and in coronary artery disease, where stents killed coronary-artery-clearing tools. Technologies change at a rapid pace, but so also does clinical practice as the understanding of disease processes evolves. Fortunately for Sensors for Medicine & Science Inc. (SMSI), the field of diabetes moved exactly in the direction that the company was headed when it was founded in 1997. Ten years later, the company now finds that its technology is perfectly positioned to ride the newest wave in diabetes care, continuous glucose monitoring.

We first wrote about SMSI in 1998, a promising time in the field of glucose testing. (See "Sensors for Medicine...
