A device for treating a tissue opening includes a proximal portion including an elongated flexible member, a capsule releasably coupled to a distal end of the flexible member and including a lumen extending therethrough and a clip including a pair of arms movably housed within the capsule. A suture extending along a first one of the pair of arms and including a loop at a distal end thereof extending across an opening extending through the first one of the pair of arms. A suture grabbing element extending laterally from a second one of the pair of arms and including a hook so that, when the pair of arms are moved toward a closed configuration, the hook extends through the opening to grab the loop and draw the distal end of the suture from the first one of the pair of arms toward the second one of the pair of arms.

In one embodiment, a method of repairing a heart valve accesses an interior of a patient's beating heart minimally invasively and inserts one or more sutures into each of a plurality of heart valve leaflets with a suturing instrument. The suture ends of the sutures are divided into suture pairs, with each pair including one suture end from a suture inserted into a first valve leaflet and one suture end from a suture inserted into a second valve leaflet. One or more tourniquet tubes is advanced over the suture pairs to the leaflets to draw the sutures together to coapt the leaflets and then the sutures are secured in that position.

An assembly and method for the protection of medical personnel from accidental suture needle sticks is described. The assembly includes a case containing a needle which can be retracted when not in use. The needle is extended and retracted through the engagement of a needle driver which compresses a compressible member. The compressible member exerts a force on the needle which in turn extends the needle's point beyond the casing so that the user can suture tissue. Disengaging the needle driver retracts the needle point which protects the user from accidentally receiving a needle prick from a contaminated needle between punctures.

Disclosed are devices and methods for delivering several sutures accurately and simultaneously around the perimeter of an annular prosthetic device (prosthetic heart valve, annuloplasty ring, etc.) to secure the prosthetic device within a native heart valve region. Devices can comprise a proximal handle portion including an actuator and a distal suturing portion including several curved and straight needles arrayed around the shaft axis. The straight needles and the curved needles are configured to simultaneously guide a plurality of sutures through the native tissue and through the annular prosthetic device. The actuator can cause the straight needles to move axially relative to the curved needles and can also cause the curved needles to rotate, such that the motions are coordinated to simultaneously place all the sutures.

An endoscopic suturing system and method are disclosed as are devices for use with the system and method such as a suture dispenser, a cinch device, and a tissue grasper. In one embodiment the suturing system includes a cap assembly arranged at the distal end portion of an endoscope or guide member, with the cap assembly including a rotatable needle holder. The needle holder is actuated through a transmission element extending outside the endoscope or guide member. A needle capture device may be inserted through a channel of the endoscope or guide member in order to capture a needle held in the needle holder when the needle holder is rotated so that the needle punctures tissue.

Devices and methods of endolumenal formation of gastric sleeves are described. Some embodiments allow templating of a gastric sleeve by a gastric bougie, exposing a selected amount of tissue for suturing access, while maintaining sufficient internal working space for suturing within the template lumen.

The present disclosure includes a suturing device including: a fixed arm having a fixed jaw including a first grasping slot configured to receive a needle; a movable arm coupled to a movable jaw including a second grasping slot configured to receive the needle, the movable arm configured to pivot relative to the fixed arm to pivot the movable jaw relative to the fixed jaw until the needle is received in the first grasping slot and the second grasping slot; and a needle transfer mechanism configured to grasp the needle in the first grasping slot or the second grasping slot. In some aspects, the suturing device includes a safety member configured to control when the movable arm moves. The present disclosure includes a loading apparatus including a loading slot configured to receive a fixed jaw and a slider configured to move the needle towards into the fixed jaw.

The disclosure relates generally to devices and methods for treating a tissue defect, for example, by suturing. In some embodiments, a suturing device may include an elongate member having a working channel, a suture channel, and a suture arm extending from the elongate member. The suturing device may further include a needle passer located within the working channel, the needle passer operable to deliver a needle between the elongate member and a distal end of the suture arm for suturing a target tissue, and a suture extending through the suture channel, wherein the suture is coupled to the needle. The suturing device may further include a plurality of imaging devices, wherein a first imaging device is positioned along a distal face of the elongate member, and wherein a second imaging device is positioned along the suture arm.

A surgical instrument comprising an end effector is disclosed. The end effector comprises a surgical dissector. The surgical dissector can apply mechanical and/or electrosurgical energy to treated tissue.

A stitching device includes an end effector having first and second jaw members and first and second pins, a stationary cam, and a rotary cam. The first pin is supported on the first jaw member and the second pin is supported on the second jaw member. The stationary cam defines a first cam slot, and the rotary cam defines a second cam slot. The first and second cam slots receive the first and second pins and are configured to releasably secure one of the first or second jaw members to the rotary cam such that the first and second jaw members rotate about the stationary cam in alternating fashion. During each revolution of the rotary cam, the one of the first or second jaw members rotates with the rotary cam a substantially full revolution while the other of the first or second jaw members remains stationary.
