Medical device for sensing glucose
First Claim
1. A device for the controlled exposure of a secondary device, comprising:
- a substrate having a reservoir;
an operational secondary device in the reservoir;
one or more reservoir caps covering the reservoir to isolate the secondary device from an environmental component outside the reservoir, wherein the one or more reservoir caps are impermeable to the environmental component;
means for disintegrating or permeabilizing the one or more reservoir caps to expose the secondary device to the environmental component; and
a resistive heater for selectively rendering the secondary device inoperable.

Abstract
Medical devices, utilizing multiple reservoirs to protect and selectively expose sensors or other reservoir contents, are provided having (i) a reservoir contents destruction mechanism to interrupt the release or exposure of reservoir contents, for example, to deactivate an unneeded sensor and prevent it from negatively impacting other sensors, (ii) a protective covering material layer over the sensor underneath the reservoir cap, which protects the sensor membrane and sensor during reservoir cap disintegration and then is removed, (iii) a device design for containing sensors in shallow, wide reservoir structures to enhance sensor exposure by minimizing molecular diffusion distances, (iv) an implantable sensor unit and a separate drug delivery unit, or (v) combinations thereof.

17. A device for the controlled exposure of a secondary device, comprising:
-
a substrate having a reservoir; a secondary device in the reservoir; one or more reservoir caps covering the reservoir to isolate the secondary device from an environmental component outside the reservoirs, wherein the one or more reservoir caps are impermeable to the environmental component; a biodegradable intermediary material disposed in the reservoir underneath the one or more reservoir caps and covering the secondary device; and means for disintegrating or permeabilizing the one or more reservoir caps to expose the biodegradable intermediary material to a fluid from outside the device to cause the biodegradable intermediary material to disintegrate to expose the secondary device to the environmental component. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
