The present invention relates to a suction instrument, more particularly a bipolar mapping suction instrument, for surgical purposes and to a system for suctioning fluids and tissue and for monitoring nerve tissue. The suction instrument comprises a cannula unit, which comprises an electrically conductive outer cannula tube, an electrically conductive inner cannula tube, and insulation. The electrically conductive inner cannula tube is electrically connected to a first pole of the bipolar electrical connection of the second interface. The electrically conductive inner cannula tube is arranged concentrically in the outer cannula tube which optionally can be insulated from the exterior. The electrically conductive inner cannula tube is mechanically connected to the handpiece and/or the first interface. The electrically conductive outer cannula tube is electrically connected to a second pole of the bipolar electrical connection of the second interface. The insulation is concentrically arranged between the outer cannula tube and the inner cannula tube. The insulation is configured to fully electrically isolate the outer cannula tube and the inner cannula tube in relation to one another.

A method for estimating total body water, TBW, content of a subject, comprises: receiving locally measured bioimpedances for at least two different frequencies of a stimulation current at a body part of the subject; determining a first resistance and a second resistance of the bioimpedance, wherein the first resistance corresponds to a representation of the bioimpedance being purely resistive at a low frequency of the stimulation current and the second resistance corresponds to a representation of the bioimpedance being purely resistive at a high frequency of the stimulation current; and estimating the TBW content of the subject using a ratio between the first resistance and the second resistance.

A display device including a display panel that displays an image, an input sensor disposed on the display panel, and a readout circuit that receives sensing signals from the input sensor and outputs a moisture level signal, in a skin measurement mode. The readout circuit divides the input sensor into a plurality of blocks, selects a valid sensing block based on the sensing signals from the plurality of blocks, and outputs the moisture level signal based on the sensing signals from the valid sensing block.

This disclosure sets forth various systems and methods for deploying anchored medical devices within a human or animal. The medical devices may deliver payloads, such as various sensors, electrodes, transmitters, cameras, electrical or other interventional devices, drugs or therapeutics. The devices may have one or more anchors, which attach the device to an anatomy of interest. This allows for methods and processes to be performed over periods of time, such as extended delivery of a therapy or real time sensing of characteristics inside a body, which the device remains within a given location.

A method of controlling an analysis of electromagnetic (EM) signal of a human subject. The method comprises positioning an EM transducer unit in front of a skin area above a target intrabody volume of a human subject, the EM transducer unit having at least one EM transducer, a pressure applying unit that applies a variable pressure on the skin area, and a pressure sensor, measuring at least one pressure parameter indicative of the variable pressure using the pressure sensor, capturing EM signal using the at least one EM transducer, and performing an analysis of the EM signal to infer at least one intrabody parameter of the target intrabody volume. The analysis is controlled according to the at least one pressure parameter.

An intraoral moisture measuring device includes: a swing member that swings with respect to a main body about a predetermined swing center; a moisture amount detection unit provided at a tip of the swing member, for detecting a moisture amount by being directly or indirectly abutted against a measurement site in a mouth; and a biasing member for biasing the swing member in one of swing directions. Consequently, the intraoral moisture measuring device is capable of measuring intraoral moisture in a simple and highly-accurate manner.
