A medical device that includes a handle, a shaft extending distally from the handle, an end effector extending distally from the shaft, a first actuator movably coupled to the handle, and a second actuator movably coupled to the handle. The first actuator is configured to (1) articulate the shaft in response to translating the first actuator in a first direction relative to the handle and the second actuator, and (2) actuate the end effector in response to translating the first actuator in a second direction relative to the handle and the second actuator. The second actuator is configured to (1) articulate the shaft in response to translating the second actuator in the first direction relative to the handle and the first actuator, and (2) actuate the end effector in response to translating the second actuator in the second direction relative to the handle and the first actuator.

A medical device system includes an insertion device and a medical device. The insertion device includes an insertion device handle, including a port on a handle body. The insertion device also includes an insertion device shaft extending from the insertion device handle. The insertion device shaft includes a working channel connected to the port. The medical device includes a medical device handle, including a movable handle portion and a stationary handle portion. The movable handle portion includes a ball portion movably positioned within a cavity in the stationary handle portion. The medical device also includes a medical device shaft. The medical device shaft is configured to be delivered through the port in the insertion device handle and through the working channel in the insertion device shaft. Movement of the movable handle portion relative to the stationary handle portion controls movement of a distal portion of the medical device shaft.

Medical systems, devices, and related methods

A medical device that includes a handle including a plurality of actuators. The handle defines a longitudinal axis extending through a distal end of the handle. The device includes a shaft extending from the handle and an end effector at a distal end of the shaft. A first actuator of the plurality of actuators is configured to actuate the end effector in response to translation of the first actuator relative to the handle along an axis parallel to the longitudinal axis. A second actuator of the plurality of actuators is configured to deflect the end effector relative to the shaft in response to pivoting the second actuator about an axis transverse to the longitudinal axis. A third actuator of the plurality of actuators is configured to rotate the end effector relative to the shaft in response to rotation of the third actuator relative to the handle about the longitudinal axis.

Medical device handle assemblies and methods of using the same

A medical device having multiple degrees of freedom independent of each other. The medical device includes a handle, an end effector, and a tubular section extending between the handle and the end effector. The end effector is configured to be rotated about a first axis extending through the tubular section without rotating the tubular section. And, the tubular section is configured to be rotated about the first axis with the end effector.

Medical device with multiple degrees of freedom and related methods

The present disclosure relates to compression clips, and more specifically, to compression clips delivered to a target site through an endoscope for use in tissue resection, for example, within the gastrointestinal tract. In examples, clips are configured to be actuatable in response to a compressive force to transition between an open configuration and a closed configuration. In an embodiment, a tissue clipping device may include a first member with a plurality of arms. Each of the arms may extend from a first end to a second end, and the first end of each arm may be received within the first member. The arms may be movable between the open configuration and the closed configuration. A second member may be slidably disposed with respect to the first member.

Clip devices, systems, and methods for engaging tissue

An elongated tissue traction device adhered to target tissue and configured to lift the target tissue away from surrounding tissue. The tissue traction device may lift the target tissue as a surgical procedure is performed, such as resecting or cutting of the target tissue. The tissue traction device may be a bistable spring. The tissue traction device is in a first stable configuration when initially adhered to the target tissue. The tissue traction device may be shifted (e.g., actuated) into the second configuration, such as when the tissue is resected or cut around the target tissue to which the tissue traction device is adhered. In the second stable configuration, the tissue traction device curls and lifts the target tissue from the surrounding tissue.

Devices, systems, and methods for tissue traction

A valve for use in an endoscope may comprise a proximal valve stem member having a first lumen extending from a proximal opening at a proximalmost end of the proximal valve stem member to a distal opening at a distalmost end of the proximal valve stem member. A distal valve stem member may have a second lumen with a proximal opening at a proximalmost end of the distal valve stem member. The proximalmost end of distal valve stem member may be received within the distal opening of the first lumen. The distal valve stem may be movable relative to the proximal valve stem.

Medical valve

A medical device that includes a handle, a shaft extending distally from the handle, an end effector extending distally from the shaft, and a first actuator coupled to the handle and secured to a first wire. The first wire extends through the shaft, and the first actuator is configured to pivot relative to the shaft to pull the first wire proximally and to deflect the end effector relative to the shaft.

A method for coupling a first medical device component to a second medical device component comprising altering the first medical device component from a natural state to an altered state, by reducing a cross-sectional dimension of the first medical device, fitting a first portion of the first medical device component in the altered state into a first opening of the second medical device component, wherein the first medical device component includes second portions not within the first opening of the second medical device component, and allowing the second portions of the first medical device component to revert back to the natural state.

Methods for coupling device components and related devices having such components

A medical device comprising a handle extending between a first end and a second end, a first actuator coupled to the first end of the handle, a first shaft coupled to the second end of the handle, and a second shaft extending from the first shaft, the second shaft including a first articulation section and a second articulation section, wherein an articulation of the first actuator relative to the handle is configured to articulate the first articulation section, an articulation of the handle relative to the first shaft is configured to articulate the second articulation section, and the first articulation section and the second articulation section are restricted to articulating only in a first plane.
