A surgical ligation clip capable of remote deployment through a cannula to engage an anatomical structure.

The present disclosure relates to tissue traction devices and systems. In one example, a tissue tensioning system may include a filament having a first end comprising an attachment member, a second end, and a length therebetween extendable externally along a catheter. A first tissue fastener may be engageable with the attachment member and with a target tissue. The second end of the filament may be translatable to adjust a tensional force along the filament.

Certain aspects relate to systems and techniques for articulating medical instruments. In one aspect, the instrument includes a wrist having at least one degree of freedom of movement, and an end effector coupled to the wrist. The end effector can include a cartridge for delivering a plurality of clips to tissue. The wrist may include one or more cables capable of moving an actuator with one degree of freedom of movement within the end effector to advance one or more clips through the end effector.

A clip delivery device includes a clip, a first tube configured to store the clip when the clip is closed; a second tube coupled to a proximal end of the first tube; a hook configured to hook a proximal end portion of the clip; a wire coupled to the hook, the wire is configured to pull the hook in a longitudinal direction thereof; an elongated portion coupled to a proximal end of the second tube, the elongated portion having the wire inserted therethrough; and an operating portion coupled to a proximal end of the elongated portion, the operating portion being configured to operate the wire, wherein the hook includes at least one structural mechanism that is configured to suppress rattling that occurs when the proximal end portion of the clip is pulled into the second tube.

An object of the present invention is to provide a means for fixing a pancreatic resection stump created during an operation for resecting a portion of the pancreas. The present invention provides a polymeric surgical clip characterized in that the clip comprises a first arm portion, a second arm portion, and a resilient hinge portion joining the first and second arm portions together, both the arm portions are joined to the resilient hinge portion at their bases, the first arm portion has a convex outer surface and a concave inner surface clamping the pancreas, the second arm portion has a convex or flat outer surface and a concave or flat inner surface clamping the pancreas, the first arm portion forms at its distal end a deflectable hook portion curved toward the second arm portion, and the clip is configured so that, in a closed position, a distal end of the second arm portion enters inside the curved hook portion and engages with the hook portion to lock the clip in the closed position.

A clip device includes a clip unit including an openable arm; a hook detachably connected to the clip unit; a wire configured to operate the clip unit and connected to the hook, a tubular member through which the hook is insertable; and a claw portion provided in the hook. In a first state in which the hook is connected with the clip unit, the claw portion is configured to have a radial dimension larger than an inner diameter of the tubular member, and in a second state in which the hook is disconnected from the clip unit, the radial dimension of the claw portion is equal to or less than the inner diameter of the tubular member.

A ligation device includes a first arm, a second arm, a holding tube, an operation wire, a sheath, and a link mechanism having a first link and a second link which are connected to each other and engage the holding tube with the sheath, wherein the link mechanism is configured to be switch between a disengaged configuration in which engagement between the holding tube and the sheath is released and an engaged configuration in which the holding tube is engaged with the sheath due to the operation wire.

An anchor device configured to connect a plurality of tissues to each other, includes a shaft having a longitudinal axis; and a first anchor part and a second anchor part which are separated from each other and which are each formed in the shaft. The first anchor part includes a plurality of elongated anchor arms that are allowed to be expanded in a direction of separating from the longitudinal axis of the shaft toward the second anchor part with a first position of the shaft being a base point. The second anchor part includes a plurality of elongated anchor arms that are allowed to be expanded in a direction of separating from the longitudinal axis of the shaft toward the first anchor part with a second position of the shaft being a base point.

A device for closing a tissue opening includes a proximal housing portion having a first portion, a second portion, a third portion, and a fourth portion. The first portion and the fourth portion extending transversely to a longitudinal axis of the proximal housing portion on opposite sides of the proximal housing portion. A distal portion extends from the proximal housing portion. At least the second portion and the third portion are configured to move toward the first portion.

A device includes a capsule extending longitudinally from a proximal end to a distal end and including a channel extending therethrough. The capsule is releasably coupled to a proximal portion of the device. Device also includes a first arm rigidly fixed to the distal end of the capsule to extend distally therefrom. In addition, Device includes a second arm, a proximal end of which is slidably received within the capsule so that the second arm is movable between an open configuration, in which the second arm is moved laterally away from the first arm and a distal end of the second arm is moved distally past the distal end of the first arm, and a closed configuration, in which the second arm is moved toward the first arm and the distal end of the second arm is moved proximally toward the distal end of the first arm.
