A system for forming a suture connector in situ includes a suture connector placement device having a handle, an outer shaft, an intermediate shaft, and a push rod, and a suture connector having a sleeve and a plug. The intermediate shaft is slidingly disposed through a lumen of the outer shaft, and the push rod is slidingly disposed through a lumen of the intermediate shaft. When the suture connector is in a loaded configuration within the suture connector placement device, the sleeve is radially disposed over the intermediate shaft and the plug is positioned proximal to the sleeve within the lumen of the intermediate shaft. Distal advancement of the push rod moves the plug into the sleeve and proximal retraction of the intermediate shaft releases the resilient sleeve onto the plug, thereby securing two suture portions between the sleeve and the plug. The system is then utilized to trim the suture portions.

A device for suturing an incision in an artery has a handle, a supply of suture stored on spindle housed in the handle, a tube extending from the handle having a lumen through which suture extends, and a curved needle at a distal end of the handle, the curved needle having an opening through which a free end of the suture extends. A method for suturing an incision in an artery includes creating sequential openings in first and second flaps of the incision, with loops of suture extending through openings in one flap, with a free end of suture extending through the second flap being pulled through the loops and secured to another free end of suture extending through the first flap, to close the incision.

A method for resecting a lesion in a wall of an organ of a patient includes injecting a fluid into the wall of the organ at a location proximate to the lesion, creating a wound in the wall of the organ by cutting the lesion from the wall of the luminal organ, removing at least a portion of the fluid injected into the wall of the organ, and closing the wound using a suture thread. The portion of fluid may be removed prior to or after partially threading the suture thread into the wall of the organ.

A system and method for closing a fascial opening is disclosed. The system may include a strap that may be locked into each of a pair of anchors placed anterior to a muscle and on opposite sides of a fascial opening, one or more delivery tubes for delivering the anchors, and a needle for pulling the strap into each anchor. The method may include the steps of placing a dilating port through a skin incision, inserting an anchor through the dilating port, placing a strap into the body cavity, whereupon the strap may be pulled through the anchor. A second anchor may be placed on the contralateral side of the defect so that the strap may be pulled through the second anchor and cinched tightly closing the defect. The anchors may have a locking aperture that engages with the strap.

Proposed is a trocar system for a laparoscopic surgery, the trocar system preventing improper suturing caused by shaking of the focus of a suturing needle during suturing of the peritoneal hole of the peritoneum after completion of a laparoscopic surgery, and including a suturing needle guide member having first and second suturing needle guide holes, a trocar unit detachably coupled to the suturing needle guide member and having third, fourth, fifth, and sixth suturing needle guide holes, a trocar to which the suturing needle guide member is detachably coupled and which is provided with seventh and eighth suturing needle guide holes, and a suturing needle provided with suturing thread guided through the first, third, fifth, and seventh suturing needle guide holes and second, fourth, sixth, and eighth suturing needle guide holes.

Suturing devices and systems used to close openings into a biological structure. The suturing device can comprise an elongate member having a proximal end, a distal end, one or more arms, and one or more needles. One or more sheaths may be used with the device to maintain or substantially maintain haemostasis while the device is used and while a procedure is performed in the biological structure.

Systems and methods for closing a tissue defect are disclosed. The systems may include a subcutaneous guide that is placed transcutaneously between two skin access sites and a self-locking strap that may be advanced into the body through a first access site via a first needle and then passed to a second needle. The strap may be withdrawn with the second needle through a second access site to the outside of the body. The strap may be withdrawn from the first needle, leaving the strap placed through both access sites and across the defect. As the subcutaneous guide is withdrawn from the body it pulls the captured strap such that both ends of the strap protrude from the first access site, allowing the strap to be tightened around the defect. Devices for closure of a tissue defect are also disclosed.

A suturing system including an elongate distal member and an elongate proximal member proximal the elongate distal member, the elongate proximal member having a lumen. A needle deployment actuator extends to the elongate distal member and is configured to initiate proximal movement of a needle toward an opening of the elongate proximal member. A guide is disposed within the elongate proximal member, a perimeter of the guide forming a plurality of needle receiving gaps that, when viewed in cross-section, are circumferentially spaced about the deployment actuator with a portion of the guide disposed between adjacent needle receiving gaps extending outwardly towards a wall of the lumen of the elongate proximal member.

This application provides a linear stapler with an adjusting mechanism having wider adjusting scope and more suitable pressing force and being more convenient to operate, and including an adjusting shift lever with at least one step surface on each of upper and lower ends, an adjusting slider with multiple step surfaces on an end surface close to the adjusting shift lever, and an adjusting chassis having multiple step surfaces on an end surface close to the adjusting shift lever. The adjusting shift lever rotates with a shifted adjusting knob to generate relative displacement vertical to the step surface with the adjusting slider at one end and relative displacement vertical to the step surface with the adjusting chassis at the other end, and drive a nail abutting seat subassembly to rotate relatively to a nail bin seat, until the thickness of clamped tissue is consistent in near and far ends.

A vessel closure device including a proximal end including a handle with first and second actuators, a distal end including a suturing mechanism, and first and second needles associated with the suturing mechanism. At least one of the first and second needles is coupled to the first actuator. The second actuator is coupled to the suturing mechanism. The suturing mechanism includes a pivotal element capable of being moved by the second actuator between an insertion and removal orientation, a first deployed orientation, and a second deployed orientation. The suturing mechanism is activated within the vessel through an opening in the wall of the vessel and the first and second needles are directed through the vessel wall adjacent to the opening to direct a tensile member adjacent to the opening for closing and sealing the opening.
