A device for treating a tissue opening includes a capsule extending longitudinally from a proximal end to a distal end and including a lumen extending therethrough; a pair of arms movably housed within the lumen of the capsule such that the pair of arms are movable between an open configuration and a closed configuration, the pair of arms being biased toward the open configuration such that when the pair of arms are moved distally with respect to the capsule, distal ends of the pair of arms are separated from one another to receive target tissue therebetween; a needle releasably connected to a first one of the pair of arms, the needle extending laterally inward toward a second one of the pair of arms and including a connecting structure extending along a portion thereof, the second one of the pair of arms including an opening located so that, when the pair of arms are moved to the closed configuration, the connecting structure of the needle engages the opening; and a suture extending from a portion of the needle proximally through the capsule.

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.

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.

A stitching device includes a handle assembly and an elongate shaft assembly. The handle assembly includes a main rod and a drive conversion assembly including a cam wheel, a pivot block, first and second links, and a pawl. The pawl is operatively coupled to the main rod, and is configured to engage the pivot block to cause rotation of the pivot block which, in turn, causes reciprocating displacement of the first and second links. The elongate shaft assembly includes first and second blade drive members coupled to the cam wheel. The tool assembly includes first and second jaws and first and second blades. The first and second blades are operatively coupled with the respective first and second blade drive members, wherein axial displacement of the main rod transitions the first and second jaws between open and closed positions and causes reciprocating axial displacement of the first and second blades.

A surgical suture and method of suturing is described. The surgical suture includes a pair of matched fastening elements connected by a length of suture. The fastening elements have interlocking components, allowing a surgeon to adjust the tightness of the suture. Fastening element holding devices are also provided to guide the use the surgical suture. The method includes placing the fastening elements in the holding devices, threading one or both of the fastening elements through the body of the patient, and securing the surgical suture, and removing the holding devices.

Suture passers and methods of use. Described herein are suture passers preloaded with suture, including cartridges that couple to a suture passer to form a loaded suture passer; the suture passer may be operated to pass one or more lengths of suture without having to be manually reloaded. In particular, described herein are preloaded and automatically reloading apparatuses typically.

An end effector assembly for a surgical stitching device is provided. The end effector assembly includes an end effector, a housing, and a needle. The end effector includes a first jaw member and a second jaw member. The housing is movable relative to the end effector. The needle is releasably coupled to the housing and movable relative to the housing between a first, insertion position and a second deployed position. The needle is adapted, when in the second, deployed position, to releasably couple to one or both of the first jaw member and the second jaw member of the end effector.

A suturing device with built-in needle-transfer of a double-ended needle has a first jaw element with a first needle lock device for retaining and releasing a first end of the needle; a second jaw element with a second needle lock device, wherein the jaw elements are movable between an open and closed position; and a needle-transferring mechanism for alternately transferring the needle from one of the jaw elements to the other when the jaws are moved from the open to the closed position. The needle-transferring mechanism includes a first rotatable wheel connected to the first needle lock device, the first wheel having a first wheel inner portion rigidly connected to a first wheel outer portion and a second rotatable wheel connected to the second needle lock device, said second rotatable wheel comprising a second wheel inner portion rigidly connected to a second wheel outer portion.
