Patent number: 8777968Abstract: A tissue fastening device includes a suture clip holder and a suture cutter. A suture clip can be releasably secured to the suture clip holder, and a suture line or lines can pass through the clip and adjacent the suture cutter. A first movement of a control handle causes the suture clip to be released from the suture clip holder, and a second movement of the control handle causes the suture cutter to cut the suture line or lines. The first movement is different from the second movement. The first movement can be rotational, with the second movement being longitudinal. Alternatively, the first movement can be longitudinal, with the second movement being rotational. The device may include a main body, an inner body, and an outer body.Type: GrantFiled: August 27, 2012Date of Patent: July 15, 2014Assignee: Edwards Lifesciences CorporationInventors: David J.
