  • Publication number: 20210169458
    Abstract: An apparatus for sealing a puncture includes a cartridge, a pusher member, a sealant, and a tamping device on a proximal end of the cartridge. During use, the cartridge, sealant, and pusher member are advanced over a positioning member and into the puncture by advancing a cartridge hub carrying the tamping device. When further distal advancement of the cartridge is limited, the cartridge hub is further advanced, activating the tamping device, and causing the pusher member to advance relative to the sealant to compress the sealant within the puncture.

  • Publication number: 20200375582
    Abstract: An apparatus for sealing a puncture includes a positioning member including a proximal end, a distal end sized for insertion into a puncture, an expandable element on the distal end, and a tension indicator on the proximal end. The tension indicator includes a distal housing portion fixed relative to the proximal end, and a proximal housing portion or handle movable proximally relative to the distal housing portion. The handle is biased towards the distal housing portion such that, when sufficient tensile force is applied between the expandable element and the handle, the handle moves away from the distal housing portion. During use, the distal end is introduced through a puncture into a vessel, the expandable element is expanded, and the positioning member is partially withdrawn until the expanded element contacts a wall of the vessel and the handle separates from the distal housing portion, indicating that sufficient tension is applied.

  • Publication number: 20200129165
    Abstract: 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.

  • Publication number: 20190350592
    Abstract: Systems and methods for embolizing body lumens are provided that include a mixing component provided in a flow path between two chambers, e.g., syringes, such that one or more actuators may direct embolic material back and forth between the two chambers through the mixing component to mix the embolic material. Once mixed, the embolic material may be delivered from one of the chambers through a catheter into a patient's body to embolize a target location.

  • Patent number: 10213191
    Abstract: 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.

  • Patent number: 10149670
    Abstract: Apparatus for sealing a puncture communicating with a blood vessel includes a porous carrier formed from lyophilized hydrogel or other material. The plug may include at least first and second hydrogel precursors and a pH adjusting agent carried by the porous carrier in an unreactive state prior to exposure to an aqueous physiological environment. Once exposed to bodily fluids, the carrier expands as the lyophilized material hydrates to enhance and facilitate rapid hemostasis of the puncture. When the plug is placed into the puncture, the natural wetting of the plug by bodily fluids (e.g., blood) causes the first and second precursors to react and cross-link into an adhesive or “sticky” hydrogel that aids in retaining the plug in place within the puncture.

  • Patent number: 9289195
    Abstract: Apparatus for sealing a puncture communicating with a blood vessel includes an introducer sheath, an occlusion member with a balloon thereon, a retraction assembly, and a syringe assembly including sealing material therein. During use, the introducer sheath is introduced into the puncture. With the balloon in a collapsed state, the occlusion member is introduced through the introducer sheath until the balloon is disposed within the vessel. The introducer sheath is coupled to the retraction assembly, the balloon is expanded, and the occlusion member is partially withdrawn to seal the puncture. A sealing compound is delivered from the syringe assembly through the introducer sheath into the puncture, the syringe assembly triggering the retraction assembly, whereupon the introducer sheath is automatically withdrawn at least partially from the puncture, delivering the sealing compound along the puncture.

  • Publication number: 20150351732
    Abstract: 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 5 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 fluid loading device is disposed on the proximal end of the wire member to receive the source of fluid and to deliver fluid within the lumen into the balloon to expand the balloon.
