    摘要: An implantable medical device is provided for controlled delivery or exposure of reservoir contents. The device may include a substrate; a plurality of discrete reservoirs in the substrate, wherein the reservoirs have interior walls and at least one opening in the substrate; reservoir contents disposed in the reservoirs; a reservoir cap closing the at least one opening of each of the reservoirs to seal the reservoir contents in each of the reservoirs; and control circuitry for selectively disintegrating the reservoir caps to release or expose the reservoir contents in vivo, wherein the interior walls of the reservoirs comprise a material to protect the substrate in vivo. For example, to enhance the resistance of the substrate to etching in vivo, the interior sidewalls of the reservoirs may include a protective coating (such as gold, platinum, carbon, silicon carbide, silicon dioxide, or platinum silicide), or the sidewalls may include a doped silicon.

    摘要: Sensor devices and methods are provided for detecting the presence or concentration of an analyte in fluid. The device has a reservoir; a working electrode located within the reservoir, a catalyst covering at least part of the working electrode; an oxygen-generating auxiliary electrode in the reservoir; and a reservoir cap to isolate the working and auxiliary electrodes within the reservoir. The device further includes means for selectively rupturing the cap to permit analyte from outside the reservoir to contact the catalyst. The methods may include in vivo glucose monitoring and may include implanting the device in a patient; disintegrating a reservoir cap to permit glucose to enter the reservoir; generating oxygen using the oxygen-generating auxiliary electrode; and using a working electrode to oxidize hydrogen peroxide produced by the reaction of the oxygen with glucose in the presence of glucose oxidase, and thereby detecting endogenous glucose in the patient.
