A medical device may include a first body having a lumen and a central longitudinal axis; a second body positioned at least partially within the lumen of the first body; and an arm assembly. The arm assembly may include a first arm coupled to the first body and extending distal to the first body; and a second arm coupled to the second body and extending distal to the second body. A distal end portion of the first arm may be coupled to a distal end portion of the second arm. Distal movement of the second body may be configured to move the first arm and the second arm radially-outward away from the central longitudinal axis. Proximal movement of the second body, relative to the first body, may be configured to move the first arm and the second arm radially-inward towards the central longitudinal axis.

Medical systems, devices, and related methods

An end effector of an instrument is positioned in a patient. An ultrasonic blade of the end effector is positioned against tissue in the patient. The ultrasonic blade is activated to vibrate ultrasonically while the ultrasonic blade is positioned against tissue. At least one electrode of the end effector is positioned against tissue in the patient. The at least one electrode is activated to apply RF electrosurgical energy to tissue against which the at least one electrode is positioned against tissue.

Method of treating tissue using end effector with ultrasonic and electrosurgical features

An endoscopic tissue fastening device may include a body having a first portion and a second portion arranged alongside the first portion. The second portion may extend distally of the first portion and may terminate in a distal end face of the body. The device may further include a tissue fastening assembly having a fastening head with a proximal end and a distal end. The fastening head may be deflectable at a location between the proximal end and the distal end of the fastening head. The tissue fastening assembly may be received within a lumen of the body. Further, the body may be moveable between an unarticulated configuration and an articulated configuration. In the articulated configuration, a central longitudinal axis of the second portion of the body may be substantially parallel with a central longitudinal axis of the tissue fastening assembly.

Systems, devices, and related methods for fastening tissue

Various embodiments are generally directed to devices, systems, and methods for controlling the flow of fluids in endoscopic systems, such as endoscopic ultrasound (EUS) enabled endoscopes. Some embodiments are particularly directed to valve sets and/or valve interface mechanisms for controlling air, water, and/or suction flow through a valve well for an endoscopic system. Several embodiments are directed to user interface mechanisms and techniques for enabling an operator to interact with and control endoscope valves. Many embodiments are directed to mechanisms and techniques for translating interface input motion into valve control motions. In one or more embodiments, the valve sets and/or valve interface mechanisms may be disposable.

The cleaning valves (or valves) of the current disclosure are generally single-use devices (SUDs) and therefore disposable. Reusing SUDs can be disadvantageous, as single-use devices are not designed to be reusable. Accordingly, valves for medical devices, such as endoscopes, disclosed may be configured to transition from a first state to a second state for indication of utilization of the valve, e.g., via exposure to a valve well. The transition from the first state to the second state may prevent reuse valves of the present disclosure. In embodiments, the valve may be made from a limited number of components and materials.

Utilization indicators for single-use valves for medical devices

An apparatus includes a body, a shaft assembly, an end effector, and an articulation section. The articulation section is longitudinally interposed between a distal end of the shaft assembly and a proximal end of the end effector. The articulation section is configured to flex to thereby provide deflection of the end effector away from the longitudinal axis of the shaft assembly. The articulation section includes a first frame member, a second frame member, and a sleeve. The proximal end of the second frame member is proximal to the proximal end of the first frame member. The sleeve is disposed about the first and second frame members.

Articulation section for shaft assembly of surgical instrument

A device for treating hemorrhoids includes a first ligating member which moves between a first position in which the first member is tightened to a degree required to maintain a desired position of the first member around the first portion without significantly cutting off blood flow and a second configuration in which the first member is cinched down around the first portion to substantially cut off blood flow to the encircled first portion. Also, the device includes a first applicator having a proximal lumen and first and second opposed distal lumens open to the proximal lumen. The first member is extending from a proximal end distally through the proximal lumen into the first lumen to exit a distal end of the first lumen, loop around and enter the distal end of the second lumen. The first member is passing through the second lumen into the proximal lumen.

Device, system and method for treatment of hemorrhoids

An ultrasonic instrument includes a housing, an ultrasonic transducer support by the housing, and an integrated usage indicator. The housing is configured to removably connect to a shaft assembly. The ultrasonic transducer is configured to be acoustically connected to a waveguide and operated a predetermined number of use cycles. The integrated usage indicator is operatively connected to the housing and includes a used state indicator. The used state indicator is configured to indicate to a clinician in a used state when the ultrasonic transducer has been operated at least the predetermined number of use cycles for limiting usage of the ultrasonic transducer to the predetermined number of use cycles.
