    摘要： Apparatus and methods for sealing a puncture through tissue includes an introducer sheath sized for introduction into a puncture, cartridge sized for insertion into the introducer carrying a sealant, and a locking element for coupling the introducer sheath to the cartridge. When the cartridge is advanced into the introducer sheath, the locking element couples the introducer sheath to the cartridge such that subsequent retraction of the cartridge causes the introducer sheath to retract, thereby deploying the sealant from the cartridge within the puncture beyond the introducer sheath.

    摘要： Apparatus for sealing a puncture includes an elongate occlusion member having a balloon attached to distal ends of telescoping inner and outer members. A housing on the proximal end of the outer member includes a piston coupled to the inner member and slidable within a chamber communicating with a fluid reservoir. A switch on the housing is actuated to direct fluid from the reservoir through the outer member into the balloon to expand the balloon and into the chamber to move the piston and pull the inner member, shortening the balloon as it expands. During use, the distal end of the occlusion member is introduced into a puncture communicating with a vessel until the collapsed balloon is disposed within the vessel. The balloon is expanded, and a tensioner is connected to the housing to apply a proximal force holding the balloon against the vessel wall to seal the puncture.

    摘要： An occlusion device for sealing a puncture through tissue includes a tubular wire member having a proximal end, a distal end sized for insertion into the puncture, a lumen extending between the proximal and distal ends, a port adjacent the proximal end communicating with the lumen, and a balloon on the distal end. A source of fluid is connectable to the wire member for delivering fluid via the port into the lumen for expanding the balloon. A piston is movable axially within the wire member to allow fluid to be delivered into the lumen, to isolate the lumen, and to deliver fluid within the lumen into the balloon to expand the balloon.
