Patent number: 8992571Abstract: A suture clip having a top surface and an opposing bottom surface with a perimeter sidewall extending therebetween. An aperture extends completely through the clip between the top and bottom surfaces to form a slot. The slot extends into the clip from a mouth at a periphery on a first end of the clip to divide the clip into first and second lateral portions that are separated at the first end but connected at a second end of the clip. The slot is bounded by opposing inner sidewalls of the first and second lateral portions extending between the top and bottom surfaces of the clip. The clip has a sufficient resilient force to allow a suture to be slid into the slot and has a sufficient clamping force to retain the suture in place within the slot once a desired positioned of the suture has been attained.Type: GrantFiled: November 1, 2011Date of Patent: March 31, 2015Assignee: Abbott Cardiovascular Systems, Inc.Inventors: David J.

Patent number: 8864778Abstract: An apparatus for suturing body lumens is provided. The apparatus includes a flexible elongated member that has a proximal end, a distal end, a central passage and multiple needle lumens extending from the proximal end toward the distal end. The flexible elongated member further includes an elongated subsection spanning from the end of the needle lumens in the elongated member to a barrel portion that includes corresponding needle lumens on the proximal end of the elongated member. The elongated subsection provides sufficient space between the needles and the barrel portion to allow transapical insertion of the elongated member into a body lumen. The apparatus further includes needles disposed within and advanceable from the needle lumens. The apparatus also includes a handle disposed at the proximal end of the elongated member. The handle is operable to retract the needles through the needle lumens toward the handle at the proximal end.Type: GrantFiled: April 10, 2012Date of Patent: October 21, 2014Assignee: Abbott Cardiovascular Systems, Inc.Inventors: Aaron M.

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. Roorda, Laveille Kao Voss, David J. Milazzo, Aaron M. Fortson
