20090054926 | EXTRA-VASCULAR SEALING DEVICE AND METHOD - Various embodiments of a device are shown and disclosed for closing a vascular access puncture site following percutaneous diagnostic or therapeutic interventional procedures. In one embodiment, the closure device includes a vessel locating member, an anchor and a sealing material. The closure device may be configured to deploy the anchor and the sealing material outside of a hole in a blood vessel to close the hole. The vessel locating member may be used to locate the blood vessel to ensure that the anchor and/or the sealing material are properly placed adjacent to the hole. The closure device may also include a tamper member configured to push or tamp the sealing material against the anchor. The closure device may also include a suture that is used to hold the sealing material and the anchor together adjacent to the hole in the blood vessel. | 02-26-2009 |

20110172702 | TISSUE PUNCTURE CLOSURE DEVICE WITH AUTOMATIC TAMPING - A method and apparatus for sealing a puncture or incision formed percutaneously in tissue separating two internal portions of the body of a living being with an anchor, a sealing plug and a filament connecting the anchor and sealing plug. The method and apparatus provide for automatic tamping and/or cinching of the sealing plug when the apparatus is withdrawn from the puncture site. The automatic tamping and/or cinching is facilitated by transducing a motive force generated by the withdrawal of the apparatus into a tamping and/or cinching force. | 07-14-2011 |

20090171387 | VASCULAR CLOSURE DEVICE HAVING AN IMPROVED PLUG - Various embodiments of a device are shown and disclosed for closing a vascular access puncture site following percutaneous diagnostic or therapeutic interventional procedures. The vascular closure device includes an improved plug that is configured to be positioned adjacent to the hole in the vasculature. The plug may be shaped to prevent the plug from moving away from the hole in the blood vessel due to pulsatile pressure from the blood. In one embodiment, the plug may include a plurality of projections that extend outward from the plug and contact surrounding tissue in the tissue puncture tract to prevent the plug from moving away from the hole in the blood vessel. | 07-02-2009 |
