    • Devices and methods are provided for controlled release of chemical molecules, such as drugs. One device comprises a plurality of reservoirs; a rupturable covering, such as a thin metal film, enclosing a first end of each reservoir; a release formulation in each reservoir comprising chemical molecules for release; an expanding material layer in each reservoir; and a semi-permeable membrane enclosing a second end of each reservoir distal the release formulation, the semi-permeable membrane being operable to permit selected molecules (e.g., water) from outside the reservoir to diffuse to the expanding material layer to expand the expanding material layer and displace the release formulation in an amount effective rupture the rupturable membrane and discharge the release formulation. The device may further comprises a reservoir cap covering semi-permeable membrane and means for selectively disintegrating the reservoir cap to initiate diffusion of fluid molecules from outside the reservoir and through the semi-permeable membrane.

    • 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.
    • 提供了传感器装置和方法,用于检测流体中分析物的存在或浓度。 设备有一个水库; 位于储存器内的工作电极,覆盖工作电极的至少一部分的催化剂; 储存器中的产氧辅助电极; 以及用于隔离储存器内的工作和辅助电极的储存器盖。 该装置还包括用于选择性地破裂盖以允许来自储存器外部的分析物与催化剂接触的装置。 所述方法可以包括体内葡萄糖监测,并且可以包括将装置植入患者体内; 分解储存器盖以允许葡萄糖进入储存器; 使用产生氧的辅助电极产生氧气; 并且在葡萄糖氧化酶的存在下使用工作电极氧化由氧与葡萄糖的反应产生的过氧化氢,从而检测患者的内源性葡萄糖。
