Patent number: 9402625Abstract: A surgical stapler including a hollow shaft and a tube slidable axially within the shaft between a forward position, where one end of the tube projects beyond a free end of the shaft to enter a puncture site in a blood vessel and a rearward position, where the end of the locator tube is retracted within the shaft. A surgical staple straddles the tube and is slidable thereon forwardly towards an anvil against which the staple may be deformed to staple together the opposite edges of the puncture site. A cam mechanism drives the staple forwardly along the tube into deforming engagement with the anvil and at the same time retracts the tube into the shaft in time to allow the legs of the staple to close onto the puncture site.Type: GrantFiled: May 2, 2008Date of Patent: August 2, 2016Assignee: ABBOTT VASCULAR INC.Inventors: James Coleman, Christy Cummins, Chris Martin, Thomas Raymond Anthony, Sean Morris

Publication number: 20150223793Abstract: The present invention provides methods and devices for grasping, and optional repositioning and fixation of the valve leaflets to treat cardiac valve regurgitation, particularly mitral valve regurgitation. Such grasping will typically be atraumatic providing a number of benefits. For example, atraumatic grasping may allow repositioning of the devices relative to the leaflets and repositioning of the leaflets themselves without damage to the leaflets. However, in some cases it may be necessary or desired to include grasping which pierces or otherwise permanently affects the leaflets. In some of these cases, the grasping step includes fixation.Type: ApplicationFiled: April 28, 2015Publication date: August 13, 2015Applicant: ABBOTT VASCULAR, INC.Inventors: Eric A. GOLDFARB, Kent D.
