A medical device includes a shaft including a longitudinal axis, an end effector connected to a distal end of the shaft to move from a first orientation, where a longitudinal axis of the end effector is approximately parallel to the longitudinal axis of the shaft, to a second orientation, where an angle is formed between the longitudinal axis of the end effector and the longitudinal axis of the shaft, and an elongated member attached to a proximal end of the end effector, wherein manipulation of the elongated member moves the end effector between the first orientation and the second orientation.

Control mechanism for end effectors and method of use

According to one aspect, an instrument may include a sheath having a distal end. The instrument also may include a fluid cannula at the distal end of the sheath. The instrument also may include a cutting electrode at the distal end of the sheath. At least one of: (i) an exterior surface of the fluid cannula, and (ii) a cutting electrode surface that faces the exterior surface, is longitudinally slidable along the other of the exterior surface and the cutting electrode surface during movement of at least one of the cutting electrode and the fluid cannula relative to the other of the cutting electrode and the fluid cannula.

Multifunctional electrosurgical instruments with dynamic electrode assemblies

The present disclosure pertains to medical devices. More particularly, the present disclosure pertains to tissue clip devices and related systems and methods. In an embodiment, a tissue clip may include a grasper including jaws at a first end, and a spring portion at a second end, and a longitudinal axis extending along a length of the grasper from the first end to the second end, wherein the spring portion is configured to bias the jaws toward each other. A wedge may be slidably disposed between the jaws such that an apex of the wedge is oriented toward the spring portion. A filament may be coupled to the wedge at a first end of the filament and may extend through a channel of the spring portion of the grasper to a second end of the filament.

Tissue clip devices, systems, and traction methods

The present disclosure pertains to medical devices. More particularly, the present disclosure pertains to tissue retraction devices and related delivery systems and methods.

Devices and methods for tissue retraction

According to one aspect, a tissue fastening device may comprise a body configured to include a plurality of fasteners; an anvil rotatable relative to the body; and a tissue cutting device. The body may define a longitudinal channel configured to receive the tissue cutting device. The tissue fastening device may further comprise a fastener actuator configured to move proximally relative to the body to deploy the plurality of fasteners from the body; and an actuation wire coupled to the tissue cutting device and the fastener actuator. The actuation of the actuation wire may cause the fastener actuator to deploy at least one of the plurality of fasteners into tissue distally of tissue cut by the tissue cutting device.

Systems, devices, and related methods for fastening tissue

A medical device including an attachment device having a longitudinal axis, a pivot arm having a first end pivotally attached to the attachment device, an end effector pivotally attached to a second end of the pivot arm and configured to move from a first configuration to a second configuration, and a longitudinally extending body attached to a proximal end of the end effector. Movement of the longitudinally extending body in a proximal direction rotates the end effector from the first configuration to the second configuration, the end effector is approximately parallel to the longitudinal axis of the attachment device in the first configuration, and the end effector is angled relative to the longitudinal axis of the attachment device in the second configuration.

According to one aspect, a tissue fastening device may include a first body including a proximal end, a distal end, and defining a longitudinal axis; and a fastening device coupled to the distal end of the first body. The fastening device may include a longitudinal body comprising a cartridge; the cartridge configured to hold one or more fasteners; an anvil rotatable relative to the cartridge of the longitudinal body; a fastener actuator configured to move relative to the cartridge to deploy the one or more fasteners from the cartridge; and an actuation wire coupled to the fastener actuator, extending through the first body, and positioned at least partially exterior to the longitudinal body, the cartridge, or the anvil.

A tissue fastening device includes a body including a plurality of sidewalls defining a channel, an anvil having a proximal end and a distal end and pivotally coupled to the body and the anvil moves between an open position and a closed position, and a locking mechanism to lock the anvil in the closed position.

Locking mechanisms for grasping devices and methods of use

According to one aspect, a tissue fastening device may include a handle assembly including at least two actuators. The tissue fastening device may also include a first body extending distally from the handle assembly and defining a longitudinal axis. The tissue fastening device may also include a fastening device coupled to a distal end of the first body. The fastening device may include a longitudinal body including a channel, a cartridge configured to include a plurality of fasteners, a longitudinal channel configured to receive a device for cutting tissue, an anvil rotatable relative to the cartridge, and a fastener actuator. The fastener actuator may be coupled to one actuator of the at least two actuators and configured to move proximally relative to the cartridge to deploy the plurality of fasteners from the cartridge.

A system for treating tissue includes an applicator having a bushing and a control member and a clip assembly having a capsule with a channel extending therethrough. The channel includes proximal and distal portions. The distal portion extends distally from the proximal portion and flaring outward in a single plane to form opposing flared sections. The assembly also includes clip aims include proximal ends slidably received within the channel to move the arms between tissue receiving and tissue clipping configurations. The assembly further includes a yoke including a distal portion connected to the arms and a proximal portion configured to be connected to the control member so that longitudinal movement of the control member relative to the capsule moves the arms between the tissue receiving and clipping configurations. The yoke is positioned in the capsule so that the yoke is deformable in the plane in which the capsule flares outward.

Partially oval capsule for reloadable hemostasis clipping device

A medical device includes a shaft including a central lumen configured to direct a flow of fluid through the shaft, and an electrode positioned at a distal portion of the shaft. The electrode includes an electrode lumen in fluid communication with the central lumen, and the electrode lumen is configured to receive the flow of fluid from the central lumen. The electrode also includes one or more channels angled relative to the electrode lumen, and the one or more channels are in fluid communication with the electrode lumen to receive the flow of fluid from the electrode lumen. The one or more channels are configured to divert the flow of fluid from the electrode lumen toward one or more outlets laterally offset from the electrode lumen.

Medical devices and related methods

A medical device includes a shaft including a lumen configured to direct a flow of fluid through the shaft and an electrode. A proximal end of the electrode and a distal end of the shaft form a coupling configured to releasably couple the proximal end of the electrode with the distal end of the shaft. When the proximal end of the electrode is coupled to the distal end of the shaft, fluid delivered through the lumen is emitted from the electrode.
