    摘要： 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 is inserted through a penetration and actuated extend the foot carrying suturing attachment cuffs. 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 The cuffs lockingly engage the needles and can be withdrawn along the needle paths and through the tissue tract to form a loop of suture across the puncture. The articulating foot may be realigned with the shaft and withdrawn proximally through the tissue tract without dilating the tissue tract.

    摘要： A method of closing a puncture in a blood vessel wall, including: positioning a suture placement device in a tissue tract and into a puncture in the blood vessel wall, the placement device having a length of suture with a first end, a second end and a bight between the first and second ends with the bight being prearranged on the device to define a pre-tied knot when the first end of the suture passes through the bight; advancing the first end of the length of suture in a distal direction from the device through a first penetration in the blood vessel wall adjacent to the puncture; guiding the suture length from the first penetration across a proximal side of the puncture to a second penetration adjacent to the puncture opposite the first penetration; and advancing the suture length in a proximal direction through the second penetration, through the device, and through the bight so that the two ends of the suture length are accessible external to the tissue tract for securing the suture across the puncture to close the puncture.

    摘要： 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. The articulating foot may be realigned with the shaft and withdrawn proximally through the tissue tract without dilating the tissue tract. The suture may be provided with a bight between first and second ends, the bight including one or more loops prearranged to define a pre-tied knot when one or more ends of the suture past therethrough.

    摘要： A pneumatic pump having a variable buoyant actuator to substantially reduce the volume of a float, thereby increasing the fluid capacity for any pump of a given size. The pump includes an elongated housing, a sealable fluid entry aperture and a pipe communicating between an interior and an exterior of the housing. The housing includes a bottom wall and a cylindrical side wall extending from the bottom wall and terminating in an opening. A switchable valve control having a pod closes the opening. The pod has a plurality of valve seats and a plurality of corresponding valve elements, with the plurality of valve seats defining fluid inlet and output ports. The actuator is coupled to alternatingly placed valve elements in sealing engagement with fluid inlet and outlet ports in response to a level of fluid in the housing. The variable buoyant actuator includes first buoyant member disposed proximate to the bottom wall, and a buoyant amplifier disposed opposite to the first buoyant member, proximate to the pod. The first buoyant member is typically a cup or other similar receptacle, and the buoyant amplifier may be either an air-trap or a conventional float.
