An end effector for a surgical clip applier includes a housing, jaws that include opposed first and second jaw members, each comprising an independent structure movable relative to the other, the first jaw member defining a first inner surface and the second jaw member defining a second inner surface opposite the first inner surface, and an actuation mechanism arranged within the housing and operable to move the jaws between open and closed positions. The actuation mechanism includes an actuation plate longitudinally movable within the housing, and a transition pin extending from the actuation plate and received within corresponding slots defined in each jaw member. Linear movement of the actuation plate drives the transition pin through the corresponding slots and thereby moves the jaws between the open and closed positions.

The present disclosure relates generally to the field of medical devices for clamping a leaflet of a heart valve. In particular, the present disclosure relates to medical devices, systems, and methods for delivering artificial chordae tendineae in a patient. In an embodiment, a system may include a clamp having a plurality of arms at a first end. The plurality of arms may have a closed configuration in which the arms are oriented toward each other, and an open configuration in which the arms are oriented away from each other. A spring portion may be coupled to the plurality of arms at a second end that is configured to bias the arms to the closed configuration. The arms of the clamp may be configured to fixedly engage with a leaflet of the heart valve. The second end of the clamp may be configured to couple to an artificial chordae tendineae.

An implant includes a clip and a clip-controller interface. The clip is disposed laterally from a central longitudinal axis of the implant, includes first and second arms articulatably coupled to each other, and sandwiches a leaflet of a heart valve between the first and second arms by articulation between the first and second arms, such that the second arm is disposed laterally from the first arm. The clip-controller interface is reversibly coupled to a clip controller of a delivery tool, and includes first and second portions. The first portion is linearly slidable by the clip controller. The second portion is articulatably coupled to the first portion and to the second arm, such that linear sliding of the first portion causes the second portion to (i) articulate with respect to the first portion, and (ii) push the second arm to articulate toward the axis. Other embodiments are also described.

The present disclosure relates to a fastener applicator including a handle, a first trigger coupled rotatably with respect to the handle, and a second trigger coupled rotatably with respect to the handle. An interlock is disposed with the second trigger and comprises a cam follower engaged in a cam channel that selectively prevents rotation of the second trigger relative to the first trigger depending on a location of the cam follower within the cam channel. The location of the cam follower in the cam channel is set by a position of the first trigger. Methods of operating the various embodiments disclosed are also provided.

A gastric restrictive device including two separate elongated rigid members, at least two elongated inflatable paddings respectively along the two elongated rigid members, at least one flexible and extendable hollow tube fluidly interconnecting the at least two elongated inflatable paddings at inner ends thereof, and a two-part interlocking mechanism at outer ends of the two elongated rigid members. The at least one flexible and extendable hollow tube being bendable to fold the two elongated rigid members towards each other into a closed configuration with the two elongated inflatable paddings parallel and opposing each other and with the two-part interlocking mechanism interlockable. The device is attachable to a stomach and the at least two elongated inflatable paddings are inflatable by injecting fluid through the at least one flexible and extendable hollow tube for partially restricting the stomach without damaging the stomach tissue and with maintaining normal physiological functions of the stomach.

An occlusion device includes an elongate shaft; a lower jaw extending from a distal end of the elongate shaft; an upper jaw pivotably mounted relative to the lower jaw; and a control member at a proximal end of the elongate shaft, the control member being operatively associated with the upper jaw to cause pivot of the upper jaw relative to the lower jaw. A method is also disclosed.
