Each tab extension assembly is able to be adjusted in order to individually control the extension or contraction of a side of the tab thereby enabling adjustment of the height and/or angle of the tab with respect to the body of the bone fusion device. Each tab extension assembly is able to be individually adjusted such that the side controlled by each assembly is raised or lowered until the desired tab angle is achieved. The tab is advantageously positioned and angled to correspond to the vertebrae to help brace the device until the bone has fused.Type: GrantFiled: January 18, 2017Date of Patent: December 25, 2018Assignee: Neuropro Technologies, Inc.Inventors: Steven E. Dietzel, Kreigh R. Williams, Gregory C. Stalcup, Nicklas P. Thystrup, Gary R. McLuen

Patent number: 10076415Abstract: A system for implanting a repair device onto a native valve of a natural heart to repair the native valve of a patient during a non-open-heart procedure. The system includes a base assembly having a plurality of pivoting links, a pair of paddles attached to the base assembly, a pair of gripping members attached to the base assembly, and at least one coaptation or spacer element disposed between the pair of gripping members. Movement of the pivoting links of the base assembly causes the paddles to move between an open position and a closed position. The paddles and the gripping members are configured to attach to valve leaflets of the patient. The coaptation or spacer element is configured to fill at least a portion of a gap between the valve leaflets of the patient.Type: GrantFiled: January 9, 2018Date of Patent: September 18, 2018Assignee: Edwards Lifesciences CorporationInventors: Asher L.
