Patent number: 8747471Abstract: An implant for insertion into a patient includes a superior surface disposed at a first end of the implant and an inferior surface disposed at a second, opposite end of the implant. The superior and inferior surfaces of the implant are constructed with curvatures that approximately match the morphology of vertebral endplates. The inferior surface and superior surface may include the same or different radii of curvature within the coronal and sagittal planes. The inferior surface and superior surface may be defined by spherical radii. The radius of the superior surface may be about 60 percent to 74 percent of the radius of the inferior surface.Type: GrantFiled: April 13, 2006Date of Patent: June 10, 2014Assignee: Warsaw Orthopedic, Inc.Inventors: William Albans, Eric S.

Patent number: 8366776Abstract: A vertebral implant for use in establishing desired spinal curvatures includes separate implant bodies. Each body may include an associated angle between inferior and superior surfaces of the body. Further, the implant bodies may be stacked so that the associated angles are oriented in different anatomical planes. The implant bodies may be secured to one another with a connector. The implant bodies may be used either independently or in conjunction with one another to achieve a desired spinal curvature. Each implant body may include bone engagement features that extend outward from the superior and inferior surfaces of the implant body. The implant bodies may include recesses that are positioned to correspond to the bone engagement protrusions in other implant bodies to allow contact between the inferior and superior surfaces of the respective implant bodies.Type: GrantFiled: April 13, 2006Date of Patent: February 5, 2013Assignee: Warsaw Orthopedic, Inc.Inventor: Eric S.

Publication number: 20110077741Abstract: A vertebral implant for use in vertebral fusion surgeries includes a body with an exterior surface and an interior surface. The interior surface defines an interior cavity into which bone growth promoting materials such as bone graft are insertable. The body also includes a plurality of apertures that extend from the exterior surface to the interior surface. Further, the vertebral implant includes a cutting feature to decorticate bone that protrudes outward from the exterior surface at each aperture. The cutting feature is shaped so that as a cutting force is applied to move the implant in a cutting direction, the removed bone matter is directed through the apertures and into the interior cavity.Type: ApplicationFiled: December 7, 2010Publication date: March 31, 2011Applicant: Warsaw Orthopedic, Inc.Inventor: Eric S.

Patent number: 7850732Abstract: A sacral prosthesis for a partial or complete sacrectomy has a central body with a platform on a superior face thereof; first and second arms extending superiorly and laterally from the central body, with the arms including respective terminal portions for anchoring to a respective ilium. The terminal portions are held spaced from one another and the central body is suspended by the arms such that the platform is disposed inferiorly to the terminal portions at a fixed position relative thereto. The sacral prosthesis supports a spinal column against inferior displacement by supporting a vertebral body with the platform, while advantageously simultaneously preventing relative lateral displacement of the ilia. The sacral prosthesis may advantageously be formed of a radiolucent material.Type: GrantFiled: December 11, 2006Date of Patent: December 14, 2010Assignee: Warsaw Orthopedic, Inc.Inventor: Eric S.

Patent number: 7789895Abstract: A sacral reconstruction fixation device aids in stabilizing the pelvis and the lumbar spine after a sacrectomy in cooperation with a spinal rod and transiliac rod. A pair of the fixation devices may be secured to respective ilia and respective spinal rods. The transiliac rod may be secured to both of the fixation devices. The fixation devices include first and second parts that are initially relatively rotatable about a common axis to aid in connecting the fixation devices to the spinal rod and transiliac rod. The body part is intended to be mated to the spinal rod, while the second part is intended to be mated to the transiliac rod. The fixation device's parts are subsequently locked against rotation and against longitudinal translation, advantageously both relative to each other and the rods.Type: GrantFiled: December 26, 2006Date of Patent: September 7, 2010Assignee: Warsaw Orthopedic, Inc.Inventor: Eric S.

Publication number: 20080187982Abstract: A method of accelerating decomposition of non-living plant material from a ground surface. The method employs the application of a saprotroph containing suspension to non-living plant material such as leaves or the stubble of a cultivated crop. The suspension is formulated with a pH and nutrient level whereby the physiologic activity of the saprotroph is optimized. The deposited saprotroph containing suspension accelerates the natural decomposition process without decomposing living plant material. A resulting humus is thereby formed which brings nutrients back into the ground surface.Type: ApplicationFiled: February 3, 2007Publication date: August 7, 2008Inventors: Eric S. Heinz, John J. Krajewski

Publication number: 20080161821Abstract: A surgical tool for manipulating a surgical insert selectively clamps the insert between one or more moveable arms and a distal tip portion of a driver shaft assembly. The insert may be clamped or released depending on the position of a slider associated with the driver tip portion, and the slider may also function to help auto-release the insert. In a forward clamping position, the slider urges the arm(s) toward the driver tip portion to clamp the insert therebetween. In a rearward release position, the slider allows the arm(s) to move away from the driver tip portion to release the insert. The tool may also or alternatively allow for the tool's handle to be either longitudinally coupled or longitudinally decoupled from the driver shaft assembly. When decoupled, the driver shaft assembly may be impacted to help drive the insert into the desired location.Type: ApplicationFiled: October 16, 2006Publication date: July 3, 2008Applicant: Warsaw Orthopedic, Inc.Inventor: Eric S.
