    摘要： A method for programming an implantable medical device for stimulating a human or animal heart with the help of a programming device. The method comprises the following steps: a) providing a first input parameter to the programming device, the first input parameter being indicative whether a first stimulation unit is to be used to stimulate the His bundle of a heart; b) if the first input parameter indicates that the first stimulation unit is to be used to stimulate the His bundle of the heart, supporting a user of the programming device to configure the implantable medical device for His bundle pacing by automatically proposing at least one stimulation parameter and an assigned stimulation parameter value specifically adapted for His bundle pacing; c) allowing programming of the implantable medical device by allowing setting the at least one stimulation parameter value.

    摘要： A medical device for injecting fat while simultaneously allowing the injection site to be viewed with ultrasound. The device may comprise a handle with a front portion and a rear portion, a cannula having a cannula tip, extending from the front portion of the handle, and an ultrasound probe attached to the handle, the ultrasound probe comprising an ultrasound head. The ultrasound head is aligned with and spaced apart from the cannula tip, and remains so aligned during the injection process so that the injection area may be continuously viewed during the procedure.

    摘要： An in vivo potential measurement device includes an insulating member and an amplifier. The insulating member has an electrode. The insulating member is inserted into an organ of a living body such that an outer peripheral face of the insulating member contacts with an inner wall face of the organ at a contact site. The electrode senses electric potential at the contact site. The amplifier amplifies the electric potential to obtain output voltage. The amplifier has input capacitance Cin and input resistance Rin that satisfy Cin/Ce>0.1 and 1/(2πfCeRin)>0.1, where Ce represents capacitance of the insulating member at the contact site, and f represents frequency of the electric potential at the contact site on the inner wall face. A contact state between the outer peripheral face and the inner wall face is evaluated using the output voltage.

    摘要： A discrete bioelectrical impedance identification device, comprising a control module (1) and a detection module (2), wherein the control module (1) comprises a control shell (20) and a control processing circuit (21) provided inside the control shell (20); the control shell (20) is provided with conducting strips (201) which are partially exposed out of the control shell (20); the conducting strips (201) are electrically connected to the control processing circuit (21), wherein the detection module (2) comprises a detection shell (23), a probe (231) embedded in one end of the detection shell (23), a power supply (232) embedded in the other end of the detection shell (23), and a conducting needle group (233) partially exposed out of the shell; the control shell (20) is detachably connected to the detection shell (23); when the control shell (20) is firmly connected to the detection shell (23), the conducting needle group (233) abuts against the conducting strips (201); and when the control shell (20) is separated from the detection shell (23), the conducting needle group (233) is separated from the conducting strips (201). The device can improve the utilization rate of the product and reduce the use cost.

    摘要： The present disclosure is directed to measuring impedance across a plurality of electrode pairs. The disclosed systems and methods may simultaneously provide drive signals between electrode pairs and then sense the voltage signals that develop at the electrodes. Digital signal processing may be used to synchronously demodulate the voltage signal at each electrode to determine impedances at the electrodes. Each electrode pair may be driven at a unique frequency to allow for significantly increasing a number of electrode pairs and/or increasing drive current magnitudes. Synchronous demodulation allows the unique frequencies to be detected independent of each other while minimizing crosstalk. Typically, the drive frequencies are made orthogonal by setting the drive frequencies at harmonics of a common base frequency and measuring a response over an integer number of cycles. In an embodiment, quadrature demodulation may occur providing a real component for resistive impedance and an imaginary component for reactive impedance.
