Patent number: 11426288Abstract: A unitarily formed expandable spinal implant for insertion in a disc space between two adjacent vertebrae. The unitarily formed expandable spinal implant is moveable from an unexpanded configuration to an expanded configuration, and can be manufactured by a 3-dimensional printer. The unitarily formed expandable spinal implant includes an upper portion, a lower portion, a proximal wall, a first distal wall portion, a second distal wall portion, and a separator connected by at least one point of attachment to the spinal implant. A separation tool breaks the separator free from the at least one point of attachment, and moves the separator within the implant to force expansion thereof from the unexpanded configuration to the expanded configuration.Type: GrantFiled: November 23, 2020Date of Patent: August 30, 2022Assignee: WARSAW ORTHOPEDIC, INC.Inventors: Steven DeRidder, Gregory C.

Patent number: 10695077Abstract: Apparatus and methods for spinal surgery include a retractor with an elongated body extending along a longitudinal axis between a distal end and an opposite proximal end. The retractor defines a passage between the distal and proximal ends and a window opening into the passage adjacent to the distal end. The apparatus also includes a guide member extending laterally from the proximal end of the retractor and the guide member includes a body extending along an arc. The body defines a number of trajectories each intersecting the window of the retractor. The apparatus further includes an instrument removably mounted to the guide member and the instrument is movable along the guide member and securable to the guide member in any one of the number of trajectories so that the instrument can be moved along the selected trajectory through the window.Type: GrantFiled: March 30, 2016Date of Patent: June 30, 2020Assignee: Warsaw Orthopedic, Inc.Inventors: Kevin T. Foley, Gregory C. Marik, Newton H. Metcalf, Jr., Danish Siddiqui
