A surgical light is provided, the surgical light comprising a light head including at least one illuminant configured to generate an illuminated area on a surgical site, and a sensor attached to the light head, wherein the sensor is configured to identify items used in surgery, and the sensor is attached to the light head such that a detection volume of the sensor is directed to the illuminated area.

Systems and methods for effecting bariatric procedures are disclosed. Each system includes an instrument, a control valve and, optionally, a suction controller. The instrument is in the form of an elongated, flexible sizing member having a distal end portion arranged for anchoring in the patient's stomach and for enabling fluids to be removed from the patient's stomach. The elongated flexible sizing member is configured to produce near infrared fluorescence to facilitate its location within the patient's stomach and to provide visual information about location of certain relevant internal anatomical features. Suction is applied to the patient's stomach by the distal end portion of the instrument to drain gastric fluids and to bring adjacent portions of the patient's stomach into engagement with the instrument to provide a visually perceptible delineation line along which a portion of the stomach may be resected, sealed and tested.

Disclosed herein is a stone removing apparatus and a stone size measuring method, which can take a picture of a stone and measure the size of the stone in order to stably remove the stone without damaging a human body. The stone removing apparatus includes: an insertion tube having an inner space; a guide tube inserted into the inner space of the insertion tube to be moved; a wire inserted into the guide tube to be movable; a basket disposed at the front of the wire to grasp a stone; an imaging unit disposed at the front end of the guide tube in order to take an image of a stone grasped by the basket; and a control unit electrically connected with the imaging part to analyze the image taken by the imaging unit, wherein the control unit calculates a distance between the imaging unit and the basket to measure the actual size of the stone using the calculated distance.

A method for performing percutaneous spinal interbody fusion on a spine of a patient can include inserting without direct visualization a neuro-monitoring dilating probe into the patient, performing neuro-monitoring via the neuro-monitoring dilating probe, advancing the neuro-monitoring dilating probe into a disc space, passing a second dilator over the neuro-monitoring dilating probe, and advancing the second dilator into the disc space. A kit for performing percutaneous spinal interbody fusion can include a neuro-monitoring dilating probe, a second dilator, a tissue removal tool, an access portal comprising an adjustable depth stop, and a discectomy verification device.

A medical device may include a handle assembly having an actuator and a sheath. The sheath may extend between a proximal end and a distal end. The proximal end of the sheath may be coupled with the actuator. The medical device may further include an end-effector moveable relative to the sheath between an extended configuration and a retracted configuration. The end-effector may include a plurality of expandable legs. Each of the plurality of expandable legs may include a plurality of first indicia and a plurality of second indicia. A color of each of the first plurality of indicia may be different than a color of each of the second plurality of indicia.

A device for detecting postpartum hemorrhage is provided. A mat defines a proximal end and a distal end. The mat is configured to be disposed between a support and a patient and has a surface with a fluid flow region configured to direct flow of bodily fluids from the patient towards the distal end of the mat. A first detachable and optionally sealable bag is configured to receive the bodily fluids from the patient in a first operational mode of the device. A second sealable bag is configured to receive the bodily fluids from the patient in a second operational mode of the device. The second sealable bag comprises a visual volume indicator to measure the bodily fluids collected in the second sealable bag.

A method to guide in preparation of a bone relies on an instrument having a shaft with a working end and a stop member. The shaft is free to translate along an axis. Surgical planning data is registered to the bone to determine intra-operative coordinates of the desired axis and depth. The instrument holder is positioned by the bone so the stop member contacts the instrument holder to prevent translating beyond the desired depth. Alternatively, an arm is manipulated to align the instrument with the desired axis. The working end rests on the bone to define a linear separation to the desired depth. By proximally translating the instrument holder to contact the stop member and distally translating the instrument holder along the shaft, the stop member physically stops translating beyond the desired depth. A surgical system for performing the methods is provided; a reamer or impactor are also disclosed.

An ablation catheter system includes: a catheter shaft; a balloon attached to the catheter shaft; a lumen extending through the catheter shaft in a longitudinal direction thereof and communicating with the interior of the balloon; a heating electrode and a temperature sensor provided in the interior of the balloon; a heater that applies electrical energy to the heating electrode; a pressure sensor; a balloon volume sensor; and a processor that calculates the estimated depth of ablation, using as variables, heating temperature of a generator, ablation time of the generator, a value of balloon pressure obtained from the pressure sensor and a value of balloon volume obtained from the balloon volume sensor.

Methods for estimating of the effectiveness of catheter ablation procedures to form lesions. Lesion effectiveness parameters are received, and effectiveness of a corresponding ablation (optionally planned, current, and/or already performed) is estimated. The estimating is based on use by computer circuitry of an estimator constructed based on observed associations between previously analyzed lesion effectiveness parameters, and observed lesion effectiveness. The estimator is used by application to the received lesion effectiveness parameters.

A tourniquet for occluding blood flow to a limb is improved by the addition of proximal and distal strain gauges. The proximal strain gauge may be monitored under conditions of total blood flow occlusion for time-varying signals indicative of volumetric limb changes arising from the subject's blood flow in the proximal section of the limb. Upon a change in limb occlusion pressure, the signals from the proximal strain gauge can be observed to change also, and the working pressure in the tourniquet can be adjusted safely in response. Automated control systems may further use inputs from a distal strain gauge and/or from a sensor that detects induced pressure changes within the tourniquet to improve the control of the tourniquet working pressure during operation to avoid unwanted blood flow past the tourniquet.
