Hemostatic clip with needle passer
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.
Endoscopic suturing system
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.
SUTURING DEVICE AND METHODS OF USE THEREOF
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.
Endoscopic needle assembly
A needle and suture assembly is provided for use with an endoscopic suturing device with a needle holder arm. The needle assembly includes a needle tip and a needle body. The needle tip has a sharp end, a capture groove, a tab groove and a plug portion positioned between the capture groove and the tab groove. The needle body has first and second ends, tip tabs, retainers for removably retaining the needle body relative to the needle holder arm, and a suture opening. The needle tip is fixed relative to the needle body by plastic deformation of the tip tabs into the tab groove. A suture extends into the suture opening of the needle body and is fixed therein.
Method and apparatus for passing suture
A device is disclosed that can pierce and hold tissue and then pass suture through tissue. The device can have a shuttle that can removably attach to a suture and jaws that can be rotatably opened and closed with respect to each other. A method for using the device to repeatedly pass the suture through the tissue without removing the suture or device from the target site is also disclosed.
Longitudinal needle passer
A device for passing a needle and suture longitudinally through a target tissue includes a proximal jaw including a proximal recess and a proximal retention mechanism for releasably engaging a first end of a needle received within the proximal recess and a distal jaw movably coupled to the proximal jaw such that the proximal and distal jaws are longitudinally movable relative to one another. The distal jaw includes a distal recess and a distal retention mechanism for releasably engaging a second end of the needle received within the distal recess. The proximal and distal jaws are movable between a first state, in which the proximal retention mechanism is in a locked configuration and the distal retention mechanism is in an unlocked configuration, and a second state, in which the proximal retention mechanism is in an unlocked configuration and the distal retention mechanism is in a locked configuration.

The device can have a shuttle that can removably attach to a suture and jaws that can be rotatably opened and closed with respect to each other. A method for using the device to repeatedly pass the suture through the tissue without removing the suture or device from the target site is also disclosed.
SUTURE NEEDLES WITH FLEXIBLE AND NON-FLEXIBLE COMPONENTS
Disclosed is a suturing needle having a thread attachment portion and a ramp portion comprising a tapered portion extending from a proximal end of the needle to cover at least a portion of a suture thread swaged in the thread attachment portion. The tapered portion of the ramp portion provides a smooth transition from a diameter of the suture thread to a diameter of the needle body. The tapered transition portion allows for engaging the suture needle on rollers of a rotational needle driver in one smooth motion. The suturing needle includes a hollow flexible extension component having a distal end and a proximal end, the distal end connected to the proximal end of the thread attachment component, and the proximal end attached to the distal end of the tapered extension ramp portion. The suturing needle can include a combination of flexible and non-flexible sections and/or a combination of straight and curved sections.
HEMOSTATIC CLIP WITH NEEDLE PASSER
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.
METHOD AND APPARATUS FOR PASSING SUTURE
A device is disclosed that can pierce and hold tissue and then pass suture through tissue. The device can have a shuttle that can removably attach to a suture and jaws that can be opened and closed. A method for using the device to repeatedly pass the suture through the tissue with or without removing the suture or device from the target site is disclosed.
