The present disclosure is directed a method and device for unlatching a clip. The clip may have first and second leg members, the first leg member having a hook member and the second leg member having a tip member restrained by the hook member in the latched configuration. The method may include receiving the clip between first and second jaw members of a device and engaging the hook member of the first leg member with a wall of the second jaw member. The method may further include pressing on an outer surface of the first leg member with the first jaw member to open the hook member and release the clip from the latched configuration and receiving the tip member in a channel of the second jaw member after being unrestrained by the hook member where the tip member is spaced apart from the hook member.

A surgical clip for a clip applier to ligate vessels. The clip contains two opposing legs connected in parallel by an apex to form a U-shape. Each leg has an outer surface with a half-round cross-sectional configuration for minimizing tissue damage by preventing clip scissoring during ligation. Each leg has an inner surface with a flat central surface, two concave grooves on opposing sides of the central surface, and two convex ridges on opposing sides of each groove. As a vessel is ligated, vessel tissue moves into the concave grooves while remaining frictionally engaged by the compressive forces applied by the central surfaces and convex ridges of leg so that the clip does not move on the vessel. The edges of the grooves and the edges of the ridges of each leg are rounded to prevent any cutting of the ligated vessel.

A method of compressing tissue during a surgical procedure is disclosed. The method comprises obtaining a surgical instrument comprising an end effector, wherein the end effector comprises a first jaw and a second jaw, establishing a communication pathway between the surgical instrument and a surgical hub, and inserting the surgical instrument into a surgical site. The method further comprises compressing tissue between the first jaw and the second jaw, determining a location of the compressed tissue with respect to at least one of the first jaw and the second jaw, communicating the determined location of the compressed tissue to the surgical hub, and displaying the determined location of the compressed tissue on a visual feedback device.

An implant delivery system including a fixation member delivery system including an elongate shaft, first and second rails, a plurality of fixation members with each fixation member slidably disposed on the first and second rails and an actuation assembly. The actuation assembly includes a first elongate member including a first plurality of engagement members disposed along the first elongate member with a distal end region of each engagement member in engagement with one of the fixation members, a second elongate member including a second plurality of engagement members disposed along the second elongate member with a distal end region of each engagement member in engagement with one of the fixation members. Additionally, cyclical actuation of the actuation assembly is configured to incrementally move the fixation members distally along the first and second rails to deploy each of the plurality of fixation members in sequence.

A clipping device includes a clip including a capsule and a pair of clip arms, proximal ends of which are slidably received within the channel to move the clip arms between an open configuration and a closed configuration. Each of the pair of clip arms includes an elongated opening extending through the proximal ends thereof. A connector includes a central portion received between the proximal ends of the clip arms and a pin extending from the central portion receivable within the opening of each of the clip arms, the connector movable from an unlocked configuration, in which the pin is received within a distal portion of the elongated opening, to a locked configuration, in which the pin is received within a proximal portion of the elongated opening, when a predetermined force is applied thereto.

A system for closing a blood vessel includes a housing having a proximal end and a distal end and configured to be held in the hand of a user, an elongate body extending from the distal end of the housing, a distal housing having a proximal end coupled to a distal end of the elongate body and having a cavity including an opening on a side of the distal housing, a lumen passing through the elongate body and terminating at the cavity of the distal housing and configured to couple to a vacuum source, a sensor carried by the distal housing adjacent the cavity and configured for identifying a blood vessel, wherein the lumen is configured to maintain a vacuum within the cavity when a probe having a vessel closure module is inserted within the lumen and the vessel closure module is within the cavity.

A clip device includes an arm portion including a plurality of arms that are biased to an open state; a pressing tube into which a proximal-end portion of the arm portion is accommodated and configured to be able to lock the arm portion in a closed state; an insertion portion connected to a proximal-end opening of the pressing tube at a distal end of the insertion portion; a power transmission member extending through the insertion portion; a link configured to detachably connect a distal-end portion of the power transmission member and a proximal-end portion of the arm portion; a first stopper configured to regulate the distal-end portion of the power transmission member from protruding from a distal-end opening of the pressing tube, and a switching portion configured to switch the clip device between a first state and a second state.

A treatment device includes an indwelling device including a treatment portion, and a tubular member including a proximal-end opening and in which a proximal-end portion of the treatment portion is disposed. The treatment device further includes an actuator including a connector releasably connected to a proximal-end portion of the treatment portion, and a power transmission member connected to the connector for moving the connector. The treatment portion can be fixed with respect to the tubular member when the power transmission member is retracted such that connector pulls the proximal-end portion of the treatment portion in a proximal direction to a predetermined position. The treatment device also includes a regulation portion for regulating a displacement of the connector in a direction separating from a longitudinal axis of the tubular member in the state in which the connector pulls the proximal-end portion towards the predetermined position.

A clipping system includes a pusher element, a holder mounted over an insertion device and clips stacked along a length of the holder. The holder includes a longitudinally channel.

Each clip extends along a curvature defining a tissue-receiving space therewithin and extends about the holder with an exterior surface of the holder holding the clip open with the first and second ends of the clip separated from one another to receive a tissue therein. Each clip is independently deployable from the holder so that, upon release of the clip from the holder, the clip reverts to a closed configuration. In the closed configuration, the first and second ends are moved toward one another to reduce a size of the tissue-receiving space so that tissue is gripped therewithin. The element is mounted over the holder and moved distally along the holder to independently deploy each clips.

Apparatus and methods are provided for occluding blood vessels and other anatomical structures. Occlusion devices are delivered percutaneously and extraluminally through a small gauge needle and include expandable elements that are deployable on opposite sides of a target vessel to be occluded. When positioned about the vessel the elements are expanded and brought together to compress and occlude the vessel. Embodiments include those adapted for temporary as well as permanent use.
