Publication number: 20140194904Abstract: A suture trimmer including an elongate shaft including an elongate lumen extending proximally from a distal end of the elongate shaft, a transverse through-opening disposed proximal the distal end of the shaft, and a groove extending proximally from the distal end of the shaft to a distal end of the opening. A fitting is disposed within the elongate lumen at the distal end of the shaft and extends distally therefrom. A cutting member is slidably received within the lumen of the shaft and configured to move between a proximal end of the opening and the distal end of the opening and cut a suture disposed within and extending from the opening.Type: ApplicationFiled: November 18, 2013Publication date: July 10, 2014Applicant: Abbott LaboratoriesInventors: T.

Publication number: 20130325058Abstract: A closure device for closing an opening in tissue is provided. The closure device includes an elongate member through which needles may be deployed. The closure device also includes a foot portion having one or more feet slidably mounted relative thereto. The feet are movable between a deployed position and a delivery position. The feet include cuffs removably mounted therein, with sutures connected between the cuffs. When the feet are in the deployed position and the needles are advanced, the needles securely engage the cuffs and draw the cuffs and suture through the lumen wall so that the opening in the lumen wall can be closed with the sutures.Type: ApplicationFiled: May 31, 2012Publication date: December 5, 2013Applicant: ABBOTT CARDIOVASCULAR SYSTEMS, INC.Inventors: Wouter E. Roorda, Douglas H. Mehl, Rizza Garcia, Timothy C. Reynolds, Dinorah Merrill, Dawn Ma, David J. Milazzo, Aaron M. Fortson

Publication number: 20130237999Abstract: Devices, systems, and methods for suturing of body lumens allow the suturing of vascular puncture sites located at the distal end of a percutaneous tissue tract. An elongated articulated foot of the device can be inserted through the penetration and actuated so that the foot extends along the lumenal axis. The foot can carry suturing attachment cuffs with one end of the cuff adapted to receive a needle, while the other end receives suture. A portion of the foot and/or lumen of the shaft can receive a portion of the suture and can include friction reducing structure that aid with movement of the sutured during removal of the cuffs from within the penetration.Type: ApplicationFiled: April 25, 2013Publication date: September 12, 2013Applicant: ABBOTT LABORATORIESInventor: Dawn Ma
