Patent number: 7491239Abstract: A spinal implant is inserted between adjacent vertebrae to function as an disk prosthesis. The prosthesis has two plates fastened to adjacent vertebrae facing each other. The facing sides of the plates each have a depending skirt formed as concentric arcs of about 90 degrees. The skirts are either bowed or tapered in the axial direction. Depressions are centrally located between the arcs of the plates and a ball is universally movable in the depressions. A spring mechanism is centrally located in the plates to provide axial compression. One plate has a through bore and one plate has a receptacle, each, receiving a sleeve with a depression for holding the ball.Type: GrantFiled: August 18, 2005Date of Patent: February 17, 2009Assignee: Joint Synergy, LLCInventors: Robert Doubler, John Hammill, Robert Diaz

Patent number: 7195644Abstract: A spinal implant is inserted between adjacent vertebrae to function as an disk prosthesis. The prosthesis has two plates fastened to adjacent vertebrae facing each other. The facing sides of the plates each have a depending skirt formed as concentric arcs of about 90 degrees. The skirts are either bowed or tapered in the axial direction. Depressions are centrally located between the arcs of the plates and a ball is universally movable in the depressions. A spring mechanism is centrally located in the plates to provide axial compression. The plates are oriented to each other with the concentric arcs of each interrupted skirt at 90 degrees and the protrusion is engaged in the depression. The plates are then rotated about 90 degrees and the opposed arcs of one plate interlock with the opposed arcs of the other plate to prevent separation in the axial direction.Type: GrantFiled: February 15, 2005Date of Patent: March 27, 2007Assignee: Joint Synergy, LLCInventors: Robert Diaz, Robert Doubler, John E.

Patent number: 7115144Abstract: A spinal implant is inserted between adjacent vertebrae to function as an disk prosthesis. The prosthesis has two plates fastened to adjacent vertebrae facing each other. The facing sides of the plates each have a depending skirt formed as concentric arcs of about 90 degrees. The skirts are either bowed or tapered in the axial direction. A protrusion is centrally located between the arcs on one plate and a depression is centrally located between the arcs of the other plate. The plates are oriented to each other with the concentric arcs of each interrupted skirt at 90 degrees and the protrusion is engaged in the depression. The plates are then rotated about 90 degrees and the opposed arcs of one plate interlock with the opposed arcs of the other plate to prevent separation in the axial direction.Type: GrantFiled: March 2, 2004Date of Patent: October 3, 2006Assignee: Joint Synergy, LLCInventors: Robert L.

The prosthesis has two plates fastened to adjacent vertebrae facing each other. The facing sides of the plates each have a depending skirt formed as concentric arcs of about 90 degrees. The skirts are either bowed or tapered in the axial direction. A protrusion is centrally located between the arcs on one plate and a depression is centrally located between the arcs of the other plate. A spring mechanism is centrally located on one of the plates to provide axial compression. The plates are oriented to each other with the concentric arcs of each interrupted skirt at 90 degrees and the protrusion is engaged in the depression. The plates are then rotated about 90 degrees and the opposed arcs of one plate interlock with the opposed arcs of the other plate to prevent separation in the axial direction.Type: GrantFiled: March 3, 2004Date of Patent: August 1, 2006Assignee: Joint Synergy, LLCInventors: Robert L.
