    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 apparatus for sealing a puncture through tissue to a vessel includes an elongate occlusion member including an expandable member, a cartridge carried on the occlusion member, and a sealant carried within the cartridge. The cartridge includes an outer member and a pusher member within the outer member. The sealant is disposed within the outer member adjacent the expandable member distal to the pusher member. During use, the occlusion member is introduced into a puncture until the expandable member and the sealant extend from the puncture into the vessel. The expandable member is expanded, and withdrawn until the expanded expandable member contacts the vessel wall, thereby withdrawing the sealant back into the puncture. The outer member is withdrawn to expose the sealant within the puncture, while the pusher member prevents removal of the sealant, and then the cartridge, occlusion member, and pusher member are successively removed.

    摘要： An apparatus for sealing a puncture extending through tissue to a blood vessel includes a guidewire including an expandable tamp, a retaining sheath for covering the tamp, and a delivery sheath including a primary lumen for receiving the guidewire therethrough and a secondary lumen for delivering sealing compound into the puncture. The guidewire is advanced into the puncture with the tamp in a contracted condition, the tamp is expanded within the vessel after retracting the retaining sheath, and the guidewire is retracted to seal the puncture from the vessel. The delivery sheath is advanced over the guidewire, and sealing compound is introduced into the puncture through the delivery sheath. After introducing the sealing compound, the delivery sheath is removed, and an introducer sheath is advanced over the guidewire to provide access to perform a medical procedure via the vessel after removing the guidewire.

    摘要： Apparatus for sealing a puncture through tissue to a blood vessel includes a cartridge including a proximal end, a distal end sized for insertion into a puncture, and a lumen extending therebetween. A bioabsorbable plug is disposed within the lumen adjacent the distal end, and an anchoring element is disposed within the lumen proximal to the plug. A pusher member is disposed within the lumen for deploying the plug and anchoring element out the distal end of the cartridge. The plug may be formed from lyophilized hydrogel and the anchoring element may be formed from air-dried hydrogel, the anchoring element hydrating slower than the plug when exposed to an aqueous environment. During use, the plug and anchoring element are delivered into the puncture, the plug is cinched against the vessel wall. Protrusions on the anchoring element engage tissue surrounding the puncture to prevent proximal movement of the plug.

    摘要： Apparatus and methods are provided for sealing a puncture extending through tissue to a blood vessel. A delivery sheath is introduced-into the puncture, and a sealing compound, e.g., precursor polymers that mix to create a hydrogel, is introduced through the delivery sheath into the puncture. The delivery sheath is then removed, an introducer sheath is advanced through the puncture into the vessel, and instruments are introduced through the introducer sheath into the vessel to perform a medical procedure. After completing the procedure, the introducer sheath is withdrawn. The sealing compound may expand into the puncture and/or tissue recoil of the surrounding tissue may cause the sealing compound to at least partially occlude the puncture to facilitate sealing and/or hemostasis.
