Publication number: 20130231701Abstract: A suture securing system is provided for use in closing a vessel puncture site while eliminating the need for sutures to be manually tied in knots. The system may include an elongate body comprising a shaft and a barrel slidably mounted on the shaft. A knot replacement element may include an outer surface and an inner lumen configured to receive suture lengths.

Publication number: 20120296347Abstract: 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: May 19, 2011Publication date: November 22, 2012Applicant: ABBOTT CARDIOVASCULAR SYSTEMS, INC.Inventors: Wouter E.
