  • Patent number: 11064869
    Abstract: Several embodiments of the present invention are generally directed to medical visualization systems that comprise combinations of disposable and resuable components, such as catheters, functional handles, hubs, optical devices, etc. Other embodiments of the present invention are generally directed to features and aspects of an in-vivo visualization system that comprises an endoscope having a working channel through which a catheter having viewing capabilities is routed. the catheter may obtain viewing capabilities by being constructed as a vision catheter or by having a fiberscope or other viewing device selectively routed through one of its channels. The catheter is preferably of the steerable type so that the distal end of the catheter may be steered from its proximal end as it is advanced with the body. A suitable use for the in-vivo visualization system includes but is not limited to diagnosis and/or treatment of the duodenum, and particularly the biliary tree.

  • 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.

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.
