Patent number: 9468539Abstract: Vertebral body replacements are provided, including at least one vertebral body replacement in the shape of an oblong object. The oblong vertebral body replacement includes a nose shape to provide as minimally invasive an installation as possible, serrations formed in the side wall of the body replacement's body to prevent expulsion once the body replacement is in place, a tapered asymmetric shape to provide spinal lordosis, and an integral protrusion for stability and to increase the bearing area to reduce contact pressure between the body replacement and the vertebral plate. Hollow passages are typically filled with bone tissue. The body is also provided with holes passing therethrough to promote tissue growth.Type: GrantFiled: January 9, 2014Date of Patent: October 18, 2016Assignee: Nabil L. Muhanna, M.D.Inventor: Nabil L.

Publication number: 20110071637Abstract: The present invention provides vertebral spacers having a lower surface and an upper surface, an anterior face and a posterior face extending from the lower surface, and at least one guiding groove for engaging an insertion tool. A system for delivering a vertebral spacer to the spinal column of a patient, includes an insertion tool, an optional guiding tool, a pusher, a vertebral spacer, and a cutting tool. The insertion tool accepts any of a pusher, a vertebral spacer, or a cutting tool and has at least one spacer guide for engaging with a guiding groove of a vertebral spacer. The vertebral spacer is inserted into a patient by inserting the insertion tool into an intervertebral space, engaging the guiding groove of a vertebral spacer with a space guide of the insertion tool, advancing a pusher into the insertion tool, thereby pushing the vertebral spacer into the intervertebral space and thereafter removing the pusher and the insertion tool.Type: ApplicationFiled: June 30, 2010Publication date: March 24, 2011Inventors: Nabil L.

Publication number: 20070276484Abstract: An insertion device for inserting an implant into a body through an incision is provided. The device includes a holder for receiving an implant and has an open downstream end that is dimensioned to be inserted into the incision and for passing the implant therethrough. The device also includes a flexible carrier that extends through the downstream end of the implant holder and is positioned along inner and outer wall surfaces of the holder. The carrier is dimensioned to frictionally engage the implant at least at a position on the inner wall surface proximate the downstream end of the holder. The carrier and the holder are configured such that when the carrier is caused to move through the open downstream end, the implant moves with the carrier, through the opening, and into the incision.Type: ApplicationFiled: February 8, 2007Publication date: November 29, 2007Applicant: INSERTION, LLCInventors: Edward Alan Abell, Nabil L.
