Abstract: This document provides methods and materials related to the non-invasive measurement of analytes in blood.

Abstract: This document relates to methods and materials involved in detecting neurochemical signals, electrophysiological signals, ions, or combinations thereof with brain tissue. For example, methods and materials for using probes to detect neurochemical signals (e.g., neurotransmitter concentrations), electrical signals, or combinations thereof during deep brain stimulation are provided.

Abstract: This document describes, among other things, a computer-implemented method that includes accessing, by a computer system, electrogram data for a patient, wherein the electrogram data is obtained using one or more leads that sense physiological electrical activity of the patient. The computer system can identify one or more waveform features from the electrogram data, and one or more correlations between values of the one or more waveform features and analyte levels. One or more estimated analyte levels in the patient are determined based on 1) the one or more waveform features identified from the electrogram data and 2) the one or more correlations. The computer system can output information related to the one or more estimated analyte levels.

Abstract: This document provides methods and materials involved in detecting and delivering neurochemical signals, electrophysiological signals, ions, or combinations thereof within a mammal. For example, systems that can include one or more implantable devices containing probes configured to detect neurochemical signals (e.g., neurotransmitter concentrations), electrical signals, ions, or combinations thereof and one or more implantable devices containing electrodes and/or microfluidic delivery components configured to deliver neurochemical signals (e.g., neurotransmitters), electrical signals, ions, or combinations thereof to one or more locations within a mammal are provided.

Abstract: This document provides methods and materials (e.g., systems) related to assessing sleep conditions (e.g., sleep apnea).

Abstract: This document provides methods and materials involved in obtaining biopsy material from the gastrointestinal tract of a mammal (e.g., a human). For example, devices (e.g., percutaneous biopsy devices) configured to allow a user (e.g., a surgeon) to obtain biopsy material from the gastrointestinal tract of a mammal in a minimally-invasive manner as well as methods for using biopsy devices are provided.

Abstract: Electronic circuits are made with a ceramic body and electrical components which can be disposed in different layers. Interconnecting means can be provided which are disposed entirely within the body. The ceramic body and the electrical components are sintered to form a monolithic structure in a single firing. The electrical components are formed in layers by mixing the electrical component in a sinterable form with a radiation sensitive material which serves as a binder. After exposure to radiation in the desired pattern the layer is developed to form the desired pattern. Multiple patterns can be formed prior to firing.
