Publication number: 20140296882Abstract: A suture applying device includes a shaft which carries a pair of needles near its distal end. The needles are joined by a length of suture, and the shaft is used to both introduce the needles into a lumen of a body structure and to draw the needles back through tissue on either side of the puncture site. After the needles have passed through the tissue, they are captured by a needle receiver and drawn outward through the tract, leaving a loop of suture behind to close the puncture site near the body lumen. The suture can then be tied or otherwise secured to close the puncture site.Type: ApplicationFiled: June 16, 2014Publication date: October 2, 2014Inventors: Wouter E.

The arms are movable between a retracted configuration, in which the arms are each aligned along the shaft, and a deployed configuration, in which the proximal end of each arm pivots respectively about the distal end of the arm so as to extend laterally away from the shaft. The expander is positioned within the shaft, and movement of the expander causes the arms to move between the retracted and deployed configurations. Methods of using the apparatus are also included.Type: ApplicationFiled: December 21, 2012Publication date: June 26, 2014Applicant: Abbott Cardiovascular Systems, Inc.Inventor: Laveille Kao Voss

Patent number: 8758399Abstract: An apparatus for occluding a venous or arterial puncture site is disclosed including a plug insertable within, or adjacent to, a puncture site in a wall of a body lumen. An insert is forced into an aperture within the plug to cause expansion thereof. The insert may be drawn into the aperture by applying tension to a line passing therethrough and secured to the insert. Barbs may secure to the plug to engage the wall of the body lumen or adjacent tissue tract. Elongate members passing through the wall of the plug may be forced outwardly into the wall of the body lumen or adjacent tissue as the insert is forced into the aperture.Type: GrantFiled: August 2, 2010Date of Patent: June 24, 2014Assignee: Abbott Cardiovascular Systems, Inc.Inventors: Aaron M.
