The present technology relates to interatrial shunting systems and methods. In some embodiments, the present technology includes interatrial shunting systems that include a shunting element having a lumen extending therethrough that is configured to fluidly couple the left atrium and the right atrium when the shunting element is implanted in a patient. The system can also include an energy receiving component for receiving energy from an energy source positioned external to the body, an energy storage component for storing the received energy, and/or a flow control mechanism for adjusting a geometry of the lumen.

Various handheld cauterization device and/or system embodiments having safety features or components incorporated therein. In certain implementations, the device can be a retractable and deployable safety shield sized to receive any known handheld cauterization device. According to other embodiments, the device can be a handheld cauterization device with a retractable and deployable cauterization tip or a retractable and deployable safety shield.

The present disclosure relates to systems and methods for activating a circuit of an implant device. Consistent with one implementation, an implant device is provided with a sensor including a working electrode (WE) and a counter electrode (CE). The sensor may be configured to generate a first current at the CE when the implant device is implanted in a body of a subject. A sensing circuit may also be provided that is electrically coupled to the WE of the sensor. The sensing circuit may be activated based on the first current and utilize the sensor to measure one or more parameters of an individual or other subject.

A pivotal bone anchor assembly includes a receiver with a base defining an internal cavity with a seating surface adjacent a bottom opening and an upper portion defining a channel configured to receive an elongate rod. The assembly also includes an anchor member having a proximal end portion with a partial spherical or spheroid shaped head to establish pivotable motion between the anchor member and the receiver, and a planar top surface surrounding an internal drive socket. The assembly further includes an insert positionable within the channel to direct a downwardly-directed force onto the proximal end portion to lock a position of the anchor member relative to the receiver, with the planar top surface remaining spaced apart from the insert so as to not directly receive the downwardly-directed force therefrom. A method of use is disclosed.

The present disclosure provides systems, methods, devices, and kits for analysis of vaginal biological samples. A device for the analysis of vaginal biological samples can include a sample collector, an extractor, and an assay cartridge. A method for the analysis of vaginal biological samples can include detecting the presence or absence of a pathology, a disease, an immune disorder, a reproductive disorder of a subject. The method may further comprise preserving, storing, or transporting the vaginal biological samples. A kit for the analysis of vaginal biological samples can include probe, reagents and instructions for detecting a nucleic acid in the vaginal biological samples.

A highly integrated analyte detection device, includes: a bottom case; a sensor including a signal output portion and a detection portion; a transmitter provided with at least two second electrical connection ends which are corresponding to the first electrical connection ends; and a connection member, arranged between the first electrical connection ends and the second electrical connection ends, including at least two conductive areas and at least one insulation area. The insulation area is provided between two adjacent conductive areas, and at least two first electrical connection ends are respectively electrically connected to the corresponding second electrical connection ends.

Disclosed is an implant intended to be introduced into a human or animal body cavity, and includes two walls intended to grip between them a biological protuberance present in the cavity in order to attach the implant to the biological protuberance. Each wall includes a structural element having corrugations such that the structural element is folded up on itself several times, enabling the wall to be folded up before the introduction of the implant, then deployed inside the cavity.

A medical instrument for providing access to the interior of the body comprises a shaft having an elongated base body and a handle. The base body extends between a distal end and a proximal end of the shaft. The handle is coupled to the base body of the shaft at the proximal end. The shaft defines at least a first channel and a second channel that extend through the shaft. The first channel provides a passage for surgical instruments through the shaft. The second channel is adapted to accommodate an observation optics. The second channel is adjacent to at least one secondary channel that is connected to the second channel.

A system includes a sensor applicator, a sensor control device arranged within the sensor applicator and including an electronics housing and a sensor extending from a bottom of the electronics housing, and a cap coupled to one of the sensor applicator and the sensor control device, wherein the cap is removable prior to deploying the sensor control device from the sensor applicator.

Techniques are described for non-invasive, cuff-less measurement of blood pressure of a user using a portable electronic device. Illumination is projected through a body part and received by photodetectors on the other side of the body part. The body part includes elastic pathways of the circulatory system through which blood flows. Cycles of contraction and relaxation by the heart cause pulse waves to travel through the blood, which cause volumetric changes in the elastic pathways. The transient changes in blood volume result in corresponding transient changes in the amount of illumination that is absorbed by the body part versus the amount that passes through to the photodetectors, as manifest by a detection output signal. Calibration data can be used to convert the detection output signal to blood pressure measurements, such as including diastolic and systolic blood pressure readings.
