    摘要： A video laryngoscope and elongate laryngoscope insertion section for a video laryngoscope, comprising a viewing port through which an imaging device within the insertion section can obtain images of a larynx, the insertion section extending between a distal end for insertion into a subject and an opposite proximal end, and having an inferior surface and an opposed superior surface, wherein the insertion section comprises a proximal region where the insertion section extends through a subject's teeth in use, a distal region extending to the distal end and an intermediate region therebetween, wherein the inferior surface of the insertion section comprises or consists of a curved region which extends from the proximal region through the intermediate region to the distal region, wherein the curved region of the inferior surface is continuously longitudinally curved along the length of the longitudinally curved region and wherein the longitudinal curvature of the curved region of the inferior surface varies in the intermediate region. Markings on an elongate laryngoscope insertion can be used to monitor depth of insertion and to indicate a path by which an endotracheal tube should be inserted.

    摘要： Disclosed herein are systems, methods, and devices for calibrating contrast measurements from laser speckle imaging systems to accurately determine unknown particle motion characteristics, such as flow rate. The calibration stores to memory calibration data, which may include a set of measurements from samples with known particle characteristics and/or estimates of noise, including the effects on contrast arising from undesired signals unrelated to the unknown particle motion characteristics. The calibration data may be accessed and used to correct an empirical measurement of contrast and/or interpolate a value of the unknown particle motion characteristic. The system may include a light source, photodetector, processor, and memory, which can be combined into a single device, such as a wearable device, for providing calibrated flow measurements. The device may be used, for example, to measure blood flow, cardiac output, and heart rate, and can be used to amplify the pulsatile signal.

    摘要： A circuit for generating a radio-frequency signal for a surgical device is disclosed. The circuit has a voltage regulator that supplies direct current (DC) voltage, a first MOSFET, a second MOSFET, and a MOSFET driver. The MOSFET driver receives the DC voltage supplied from the voltage regulator and has a local oscillator. The local oscillator switches the first MOSFET and the second MOSFET on and off at a frequency generated by the local oscillator. The circuit further includes a transformer connected to the first and second MOSFETs, having a center tap and a main voltage applied at the center tap, and providing an alternating current (AC) output.

    摘要： A catheter is provided including a first lumen and a second lumen. A first member is disposed for relative movement within the first lumen and defines a cavity. A second member is disposed for relative movement within the second lumen. The cavity of the first member is configured for disposal of the second member. The catheter may include an elongated tubular body that includes the first lumen and the second lumen. The first member may have a distal portion that extends beyond the distal end of the body. The distal portion may include the cavity. The cavity may be defined by a member lumen. The first and second members may include tubular stylettes. The second member may include a guidewire.

    摘要： A removable electrode assembly for use in combination with a forceps having opposing end effectors and a handle for effecting movement of the end effectors relative to one another. The electrode assembly includes a housing which is removably engageable with the forceps and a pair of electrodes which are attachable to a distal end of the housing. The electrodes are removably engageable with the end effectors of the forceps such that the electrodes reside in opposing relation relative to one another. The electrode assembly also includes a cover plate which is removably attachable to the housing and at least one stop member for controlling the distance between the opposing electrodes. The stop member is selectively engageable with the electrodes.
