A clipping system includes a cap configured to be mounted over a distal end of an endoscope. A clip mountable over the cap to move between an insertion configuration, in which first and second jaws extend over opposing portions of the cap so that the first and second jaws are separated from one another, a review configuration, in which the clip is moved distally relative to the cap so that a portion of the clip extends distally until at least a portion of the clip extends into a field of view of the optical system of an endoscope on which the cap is mounted, and a deployed configuration in which the clip is moved distally off of the clip so that the first and second jaws are drawn toward one another under the bias of the at least one hinge to close over tissue received therebetween.

An occlusion device includes an elongate shaft; a lower jaw extending from a distal end of the elongate shaft; an upper jaw pivotably mounted relative to the lower jaw; and a control member at a proximal end of the elongate shaft, the control member being operatively associated with the upper jaw to cause pivot of the upper jaw relative to the lower jaw. A method is also disclosed.

Polymeric ligation clips and a clip applier for applying a polymeric ligation clip to tissue are disclosed herein. More particularly, the polymeric ligation clips include separate first and second beams that can be coupled to each other and are movable from a reduced diameter open position in which minimal strain is placed on the ligation clip to a clamped position and to a clip applier for delivering such a ligation clip to a surgical site.

Devices and methods can be used for performing transoral surgery. For example, this document provides oral retractor devices and articulating surgical tools that are well-suited for transoral surgery uses. The devices and methods provided herein may be used to treat conditions such as, but not limited to, mouth cancer, throat cancer, tongue cancer, larynx cancer, tonsil cancer, obstructive sleep disorders, and pharyngeal diverticulum, to provide some examples.

A device and method is provided herein for esophageal impingement of a patient's aorta. The device may be inserted into a patient's esophagus and positioned at the location where the esophagus passes over the patient's aorta. In this position, an actuation device is used to apply pressure to the patient's aorta through their esophagus to impinge or occlude the aorta to stop or significantly reduce hemorrhaging. A manually operable actuator handle enables a physician to manipulate a head assembly of the device through three distinct degrees of freedom of movement so as to control placement and direction of force against the patient's esophagus and, in turn, their aorta.

A clipping system for treating tissue including an adapter, a clip, an extending member and a control wire. The adapter couplable to an insertion device via steering members. The steering members extend alongside the insertion device and connect to the adapter to steer the adapter between a first position and a second position. The clip mounted over the adapter. The clip includes first and second jaws connected to one another and movable between an insertion configuration and an initial deployed configuration. The extending member slidably received within one of the steering members. The control wire slidably received within the extending member and extends through the first jaw such that simultaneous longitudinal movement of the control wire and the extending member relative to the adapter moves the clip between the insertion configuration, the initial deployed configuration, and a review configuration in which the clip is separated from the adapter.

The present invention provides a clip system that is optimal for suture treatment of living tissue. The clip system includes a clip unit having a first arm and a second arm capable of opening and closing, a wire capable of opening and closing the clip, and a sheath through which the wire can be inserted. The clip unit includes a support portion that swingably supports the first arm and the second arm.

A method for characterizing a state of an end effector of an ultrasonic device is disclosed. The ultrasonic device including an electromechanical ultrasonic system defined by a predetermined resonant frequency. The electromechanical ultrasonic system further including an ultrasonic transducer coupled to an ultrasonic blade. The method including applying, by an energy source, a power level to the ultrasonic transducer; measuring, by a control circuit coupled to a memory, an impedance value of the ultrasonic transducer; comparing, by the control circuit, the impedance value to a reference impedance value stored in the memory; classifying, by the control circuit, the impedance value based on the comparison; characterizing, by the control circuit, the state of the electromechanical ultrasonic system based on the classification of the impedance value; and adjusting, by the control circuit, the power level applied to the ultrasonic transducer based on the characterization of the state of the end effector.

A tissue ligation assembly may include a surgical clip and a clip applier. The clip applier may include a first jaw member and a second jaw member for closing and/or latching the surgical clip onto tissue. The surgical clip may be loaded in the clip applier and include first and second leg members for ligating tissue. The first leg member may include a first proximal portion, a first distal portion, a first inner surface, and a first outer surface. The first outer surface may engage and/or be received in the first jaw member of the clip applier. The second leg member may include a second proximal portion, a second distal portion, a second inner surface, a second outer surface, an inner portion, and an outer portion. The second outer surface may engage and/or be received in the second jaw member of the clip applier.

Various surgical systems are disclosed. A surgical system can include a surgical robot and a surgical hub. The surgical robot can include a control unit in signal communication with a control console and a robotic tool. The surgical hub can include a display. The surgical hub can be in signal communication with the control unit. A facility can include a plurality of surgical hubs that communicate data from the surgical robots to a primary server. To alleviate bandwidth competition among the surgical hubs, the surgical hubs can include prioritization protocols for collecting, storing, and/or communicating data to the primary server.
