Publication number: 20160206440Abstract: 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: ApplicationFiled: January 21, 2015Publication date: July 21, 2016Inventors: Steven DeRidder, Gregory C.

Publication number: 20130197581Abstract: Spinous process implants and methods relate to a spinal implant with two plates that are connected together by a post. The implant is configured for each plate to be positioned on outer lateral sides of spinous processes with the post extending through the interspinous space. The second of the two plates includes a bore that receives the post, and that plate is movable along the length of the post, and selectively lockable in position. A guide is removably attached to the distal end of the post and acts to guide the placement of the second plate during assembly, particularly assembly in situ during surgery. The guide is advantageously flexible, or at least more flexible than the post, so that the guide may be routed conveniently during surgery. The guide is removable from the distal end of the post after assembly, prior to closing the surgical site.Type: ApplicationFiled: January 30, 2012Publication date: August 1, 2013Applicant: Warsaw Orthopedic, Inc.Inventors: Jeff R.
