Patent number: 8617247Abstract: An implant for an intervertebral space with a shaped body. The implant makes possible rotation of the implant about the longitudinal axis of the body in one direction and prevents such rotation in the opposite direction.Type: GrantFiled: August 30, 2011Date of Patent: December 31, 2013Assignee: DePuy Synthes Products, LLCInventors: Beat Lechmann, Robert Frigg, Roger Burki

Patent number: 8133281Abstract: An intervertebral implant with a central axis, a top part, a bottom part, a joint comprising a joint part and a joint shell, and a joining means. The top part has a top apposed surface that is suitable for placing it on a vertebra situated above it; The bottom part has a bottom apposed surface, that is suitable for placing it on a vertebra situated below it. One of the two parts is operatively associated with a convex joint part and the other part to a matching joint shell. The joint part and the joint shell are mounted against one another in a sliding manner such that the top part and the bottom part can rotate relative to one another at least about one axis of rotation. The joining means holds the top part and the bottom part together without impairing the capability of the joint to pivot while allowing a clearance between the joint part and the joint shell.Type: GrantFiled: January 23, 2006Date of Patent: March 13, 2012Assignee: Synthes USA, LLCInventors: Beat Lechmann, Roger Bürki, Robert Frigg

Patent number: 8012208Abstract: An implant for an intervertebral space with a shaped body. The implant has a top contact surface to be placed on a base plate of a body of the vertebra adjoining the implant from above, a bottom contact surface to be placed on a cover plate of a body of the vertebra adjoining the implant from below, two lateral surfaces, a front lateral and a rear lateral surface as well as a central axis that intersects the two contact surfaces, a longitudinal axis that intersects the front and rear lateral surfaces and a transverse axis that intersects the lateral surfaces. The implant also has a central plane situated between the contact surfaces and at right angles to the central axis of the body. The contact surfaces have a plurality of macroscopic teeth with central axes, where the central axes of the plurality of teeth are inclined relative to the central plane in such a manner, that a rotation of the body of 90° about the longitudinal axis is facilitated in one direction and impeded in the other direction.Type: GrantFiled: December 22, 2005Date of Patent: September 6, 2011Assignee: Synthes USA, LLCInventors: Beat Lechmann, Robert Frigg, Roger Bürki

Patent number: 7704280Abstract: An intervertebral implant including a top part, a bottom part and a joint arranged axially between the top part and the bottom part. The top part includes a top surface suitable to be placed on the base plate of a body of the vertebra adjacent and above the site of removal. The bottom part has a bottom surface suitable to be placed on the cover plate of a body of the vertebra adjacent and below the site of removal. The joint includes a convex joint part with a first articular surface and a joint shell matching it, with a second articular surface mounted in a sliding manner on the first articular surface. The intervertebral implant including a temporarily locking mechanism to fix the two parts relative to one another.Type: GrantFiled: January 23, 2006Date of Patent: April 27, 2010Assignee: Synthes USA, LLCInventors: Beat Lechmann, Roger Bürki, Robert Frigg

Publication number: 20060229724Abstract: An intervertebral implant for restoring natural function to a spine following the removal or an intervertebral disk or part thereof. The implant comprises a central axis, a top part, a bottom part and a joint arranged axially between the top part and the bototm part. The top part comprises a top surface, a ventral side surface, a dorsal side surface and two lateral side surfaces, wherein the top surface is suitable to be placed on the base plate of a body of the vertebra adjacent and above the site of removal. The bottom part has a bottom surface, a ventral side surface, a dorsal side surface and two lateral side surfaces; wherein the bottom surface is suitable to be placed on the cover plate of a body of the vertebra adjacent and below the site of removal. The joint comprises a convex joint part with a first articular surface and a joint shell matching it, with a second articular surface mounted in a sliding manner on the first articular surface.Type: ApplicationFiled: January 23, 2006Publication date: October 12, 2006Inventors: Beat Lechmann, Roger Burki, Robert Frigg
