Abstract: Biosensing platform deployed in a catheter is described which permits long-term operation of biosensors monitoring glucose and other analytes subcutaneously or intraperitoneally (IP) to manage diabetes. A method for integrating a plurality of biosensors monitoring glucose and other analytes into a catheter platform. The catheter platform comprises of electrochemical sensors, sensor electronics, RF and optical communication devices, as well as pump control electronics to facilitate glucose management. Catheter mounted biosensor is shown with micro-dialysis provisions.

Abstract: A system and method is outlined for a wearable external device that communicates with a fully implantable miniaturized biosensor platform providing fast spatial detection and accurate assessment of the position and orientation of the implant within highly scattering tissue. The device and method provides spatial (x, y) position, depth (z) and rotational (?) state of the implantable biosensor platform. The spatial (x, y) position allows the ability to turn-on only one out of an entire array of LEDs that is in line-of-sight with the implant in order to conserve power. Similarly, the depth and rotational coordinates information is used to adjust the output light intensity of the selected light emitters to compensate the power delivered to the implant. The above attributes render the system compatible for usage during intense physical activity and for added user comfort through improved skin ventilation.
