  • Publication number: 20210100429
    Abstract: An endoscopic device includes a handle body operatively couplable to a shaft housing. The handle body includes an actuator for controlling a distal end of an endoscopic shaft extending from the shaft housing. The device also includes a pull wire attachment configured to operatively couple to a pull wire extending through the shaft housing and the endoscopic shaft to the distal end. Applying tension to the pull wire deflects the distal end of the endoscopic shaft. In addition, the device includes a pulling mechanism coupled to the actuator and having the pull wire attachment extending therefrom. When the pull wire attachment is operatively coupled to the pull wire, actuation of the actuator applies tension to the pull wire and deflects the distal end of the endoscopic shaft.

  • Publication number: 20210085153
    Abstract: An endoscopic deployment device includes a body mountable on an endoscopic device, a communication interface, and a motor. The body has a movable carrier couplable to an elongated end effector device. The effector device has an end effector shaft covered by an outer sheath and an end effector extending from a distal end of the shaft. The sheath is sized and shaped for insertion through a working channel of an endoscopic shaft of the endoscopic device. The body has a carrier channel sized for the carrier to slide therein. The end effecter is actuatable between open and closed positions by sliding the carrier in the carrier channel which in turn slides the sheath over the end effector shaft to uncover/cover the end effector. Rotation of a drive shaft of the motor is sliding the carrier in the carrier channel and actuating the end effector in response to a signal.

  • Publication number: 20210052403
    Abstract: The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to delivering a variable length stent within a patient. In one example, a stent may include a body comprising coils about a longitudinal axis of the stent and along the length of the stent between a proximal end and a distal end in a substantially helical pattern. The coils may define a lumen along the longitudinal axis through the center of the body. A distal tube may have a wall extending from the distal end of the body. A first aperture may extend through the wall of the distal tube into the lumen. A distal retention member may extend from the distal tube. A distal suture may have a mid-portion. The mid-portion may extend through the first aperture.

  • Publication number: 20200337526
    Abstract: A system for modularly assembling a scope device includes an optical module which has an optical housing and a longitudinal member extending distally therefrom. A distal end of the member includes a camera for visualizing a target area, electric wires and a light source extending from the camera to the optical housing. The system also includes a deflector module coupleable with the optical module. The deflector module includes a deflector housing and a deflector shaft extending distally therefrom. The shaft includes a first channel sized, shaped and configured to receive the member therein and a deflectable portion extending along a distal portion of the shaft. The deflector housing includes an actuator for deflecting the deflectable portion, the optical and deflector housings including corresponding connecting elements to engage one another when the member is inserted through the first channel and the deflector and optical housings are coupled.

  • Publication number: 20200337529
    Abstract: A scope device includes a shaft, a deflectable portion, and a handle portion. The shaft is inserted through a body lumen to a target area within a body. The shaft defines first and second lumens extending along a proximal portion thereof. The first and second lumens are merged to form a common lumen along a distal portion thereof via a fitting having a structure which, when connected to the first and second lumens, converge the first and second lumens toward the common lumen. The deflectable portion is connected to the distal end of the shaft and includes a channel aligned with and in communication with the common lumen. The handle portion includes a connector having a first hub including a first channel open to and in communication with the first lumen and a second hub including a second channel open to and in communication with the second lumen.

  • Publication number: 20200200313
    Abstract: A fluid management system may include a fluid pump capable of generating a pulsatile flow of fluid, a fluid pathway for transporting the pulsatile flow of fluid from a fluid source through the fluid pump to a medical device, a dampening element in fluid communication with the fluid pathway and operably independent of the fluid pump, the dampening element comprising one or more barrels, each barrel including a movable seal member disposed within the barrel and a biasing member disposed within the barrel and engaged with the movable seal member, the dampening element being responsive to pressure fluctuations of the pulsatile fluid flow to actively dampen the pressure fluctuations, and a fluid flow sensor disposed along the fluid pathway between the dampening element and the medical device to measure a flow rate of the smoothened pulsatile fluid flow in both flow directions.
