  • Publication number: 20150038988
    Abstract: A device 10 for gathering tissue of a heart valve leaflet 2 may include an outer tube 16 extending in an elongation direction, a capture tool 22 moveable in the outer tube between a contained position and a use position, and a tissue securing component 32 disposed at a distal end 17 of the outer tube and adapted to be applied to tissue 8 captured by the capture tool to hold the captured tissue in a gathered configuration. The capture tool may include a first element 20 and a second element 22 that are moveable relative to one another in the elongation direction. The first and second elements 20, 22 may be operable to capture tissue 8 of the heart valve leaflet 2 therebetween and to draw the captured tissue into the outer tube 16 in the gathered configuration.

  • Patent number: 8945198
    Abstract: A side catheter branch of a catheter assembly is oriented with respect to the main or side balloons of a catheter assembly. In some examples, the orientation is accomplished by connecting the side catheter branch to the main and/or side balloons or waist portions thereof. In other examples, the side catheter branch is positioned within the folds of the main or side balloons during assembly of the catheter assembly. In this manner, the side catheter branch remains in a known orientation with respect to the main and/or side balloons prior to and/or after deployment.

  • Publication number: 20140236224
    Abstract: A vascular closure system includes a carrier tube, an expandable anchor, a bioadhesive material, a sealing tip, and a filament. The expandable anchor is mounted to the carrier tube and configured to extend through a vessel puncture to temporarily seal the vessel puncture from within a vessel. The bioadhesive material is disposed outside of the vessel and configured to seal the vessel puncture. The sealing tip is mounted to the carrier tube distal of the expandable anchor. The filament is connected to and extends proximally from the sealing tip. Applying tension in the filament maintains connection of the sealing tip to the carrier tube, and releasing the tension in the filament permits release of the sealing tip within a channel formed in the bioadhesive material upon removal of the anchor through the bioadhesive material to seal the channel.
