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.

A method for tamping a sealant, comprising:
- positioning a distal end of an apparatus in a vessel, the apparatus comprising:
- a positioning member;
- a catheter hub substantially fixed relative to the positioning member;
- a cartridge having an outer tubular member, the cartridge being axially moveable relative to the catheter hub;
- a sealant disposed in the cartridge;
- a pusher member disposed in the cartridge;
- a tamping device that receives a proximal end of the pusher member;
- and
- a latch, wherein the latch is in a first position that prevents distal movement of the tamping device;
- moving the cartridge proximally relative to the sealant and catheter hub, thereby moving the latch from the first position to a second position that allows distal movement of the tamping device;
- and
- moving the tamping device and the pusher member distally to compress the sealant.

- a sealant disposed in the cartridge;
- a pusher member disposed in the cartridge;
- and
- a tamping device that receives a proximal end of the pusher member, wherein the tamping device is initially prevented from moving distally;
- moving the cartridge proximally relative to the sealant and catheter hub, wherein moving the cartridge proximally releases the tamping device to allow the tamping device to move distally;
- moving the tamping device and the pusher member distally to compress the sealant.
