Abstract: 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 is configured to safely and accurately deploy a sealing material that undergoes a phase change when deployed inside the tissue tract. The sealing material may be a solid at room temperature and a liquid or gel at body temperature. Also, the sealing material may change from a liquid or gel to a cubic phase when it comes into contact with bodily fluids.

Abstract: 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.

Abstract: 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.

Abstract: The present invention is a device and method for controlling longitudinal movement of a tube relative to a shaft slidably disposed within the tube, especially in the catheterization of a patient. An operative segment on the shaft cooperates with an ancillary tool to create a coupling force field between the shaft and the tool. The tube can then be moved over the shaft while the coupling force field operates through the tube to restrict the movement of the shaft. In the preferred embodiment, the shaft is a guide wire and the tube is a catheter with a lumen for slidably receiving the guide wire, while the coupling force field is created magnetically. In one embodiment, the operative segment is borne on a short guide wire extension which is selectively securable to a standard guide wire.
