摘要： A membrane for implantation in soft tissue comprising a first domain that supports tissue ingrowth, disrupts contractile forces typically found in a foreign body response, encourages vascularity, and interferes with barrier cell layer formation, and a second domain that is resistant to cellular attachment, is impermeable to cells and cell processes, and allows the passage of analytes. The membrane allows for long-term analyte transport in vivo and is suitable for use as a biointerface for implantable analyte sensors, cell transplantation devices, drug delivery devices, and/or electrical signal delivering or measuring devices. The membrane architecture, including cavity size, depth, and interconnectivity, provide long-term robust functionality of the membrane in vivo.

摘要： The present invention relates generally to systems and methods for improved electrochemical measurement of analytes. The preferred embodiments employ electrode systems including an analyte-measuring electrode (16a) for measuring the analyte or the product of an enzyme reaction with the analyte and an auxiliary electrode (36) configured to generate oxygen and/or reduce electrochemical interferants. Oxygen generation by the auxiliary electrode (36) advantageously improves oxygen availability to the enzyme (38) and/or counter electrode; thereby enabling the electrochemical sensors of the preferred embodiments to function even during ischemic conditions. Interferant modification by the auxiliary electrode (36) advantageously renders them substantially non-reactive at the analyte-measuring electrode, thereby reducing or eliminating inaccuracies in the analyte signal due to electrochemical interferants.

摘要： Systems and methods for dynamically and intelligently estimating analyte data from a continuous analyte sensor, including receiving a data stream, selecting one of a plurality of algorithms, and employing the selected algorithm to estimate analyte values. Estimation can be used to compensate for time lag, match sensor data with corresponding reference data, warn of upcoming clinical risk, replace erroneous sensor data signals, and provide more timely analyte information encourage proactive behavior and preempt clinical risk. The methods can be employed in a medical device including a continuous analyte sensor (10) that provides an output signal indicative of a concentration of an analyte, a receiver to which the signal is sent (12), and an input module (14) that receives the signal.

摘要： Disclosed herein are biointerface membranes including a macro-architecture and a micro-architecture co-continuous with and bonded to and/or located within at least a portion of the macro-architecture.The macro- and micro-architectures work together to manage and manipulate the high-level tissue organization and the low-level cellular organization of the foreign body response in vivo, thereby increasing neovascularization close to a device-tissue interface, interfering with barrier cell layer formation, and providing good tissue anchoring, while reducing the effects of motion artifact, and disrupting the organization and/or contracture of the foreign body capsule. The biointerface membranes of the preferred embodiments can be utilized with implantable devices such as devices for the detection of analyte concentrations in a biological sample (for example, from a body), cell transplantation devices, drug delivery devices, electrical signal delivering or measuring devices, and/or combinations thereof.
