  • Publication number: 20050143761
    Abstract: Devices, systems, and methods for suturing of body lumens allow the suturing of vascular puncture sites located at the distal end of a percutaneous tissue tract. An elongated articulated foot near a distal end of a shaft is inserted through the penetration and actuated so that the foot extends along the lumenal axis. The foot carries suturing attachment cuffs, and needles are advanced from the shaft through the vessel wall outside of the penetration and into engagement with the needle cuffs after the foot has been drawn proximally up against the endothelial surface of the blood vessel. The cross-section of the shaft within the tissue tract can be minimized by laterally deflecting the needles as they leave the shaft, while tapered depressions within the foot can guide the advancing needles into engagement with the cuffs. The cuffs lockingly engage the needles and can be withdrawn proximally along the needle paths and through the tissue tract so as to form a loop of suture across the puncture.

  • Patent number: 6558399
    Abstract: A suture handling device for handling a plurality of suture elements is provided. The suture handling device comprises a body. It further comprises a plurality of passages defined on the body. Each passage has a mouth and an opposed end. The passages are arranged to diverge outwardly relative to one another in a direction away from their mouths, such that when the suture handling device is advanced over a plurality of spaced apart suture elements so that the suture elements enter the mouths and pass along the passages, the suture elements become spaced further apart. Advantageously, the suture handling device can be provided with an engaging formation for engaging the suture elements in the slots after they have been spaced further apart, thereby to retain the suture elements on the device.

  • Publication number: 20020111638
    Abstract: Devices, methods, and kits are provided for use with a body duct. More specifically, a device is provided for positioning sutures through a body duct. The device comprises a shaft structure for holding the end of the body duct and a suture organizer mounted about the structure. A plurality of needles are arranged on the shaft structure where each of the needles are advanced along a path in radially outward direction from the shaft structure through the end of the body duct and into a suture organizer. The suture organizer is movable relative to the shaft structure. Preferably, but not necessarily, moving the suture organizer extends the sutures from the body duct. Preferably, after the sutures have been positioned through the body duct, they may be tied off with sutures from a target body duct or tissue, where the tying off of the sutures will join the body duct to the targeted area. The suture organizer can hold the needle and sutures to facilitate the tying off of individual sutures.

  • Publication number: 20020095164
    Abstract: Systems for suturing a tissue layer having two sides with a suture by releasably retaining at least a portion of the suture in a stationary position on one side of the tissue layer. The portion of the suture is retrieved through the tissue layer from the opposite side whereby the suture is drawn from one side to the opposite side. Systems for suturing the wall of a tubular graft having two sides is also provided using a suture by releasably retaining at least a portion of the suture on one side of the wall. The portion of the length of suture is retrieved through the wall of the graft to the opposite side of the wall.
