Patent number: 8409283Abstract: An implant and method for insertion between adjacent vertebral members. The implant comprising an implant body with a base section having a plurality of base extensions, and an end cap adapted for selective axial positioning at a selected point on the base section and subsequent rotational adjustment about an implant axis. The end cap also comprising a fixed aperture and a variable aperture, both configured to receive and lockingly engage corresponding base extensions to securely maintain the end cap positioned on the base section. The fixed and variable passages are configured and located to permit rotational end cap adjustment. The implant imparts end cap height and angulation to an adjacent vertebral body at the selected or desired point when the implant is positioned and lockingly engaged in the intervertebral space.Type: GrantFiled: July 29, 2010Date of Patent: April 2, 2013Assignee: Warsaw Orthopedic, Inc.Inventors: Thomas E.

Patent number: 8268002Abstract: An implant for insertion between adjacent vertebral members, comprising an implant body with a base section having positioning teeth, and an end cap adapted for positioning at a selected point on the base section via adjustment of an approach direction. The end cap comprises a seating surface adapted to contact the base section when positioned on the implant body, an end cap angulation, and positioning passages adapted to receive the positioning teeth. The implant may further comprise a locking mechanism adapted to lockingly engage the end cap and base section and prevent axial movement of the end cap. The positioning passages and positioning teeth are complementarily configured to facilitate slideably positioning the end cap on the base section. The implant body and end cap combination will impart end cap angulation to an adjacent vertebral body at the selected point when the implant is positioned in the intervertebral space.Type: GrantFiled: January 27, 2010Date of Patent: September 18, 2012Assignee: Warsaw Orthopedic, Inc.Inventors: Jonathan Blackwell, Thomas E.

Patent number: 8177846Abstract: An implant for insertion between adjacent vertebral members, comprising an implant body with at least one base section and an end cap. The end cap is adapted for selective positioning on a base section via rotational adjustment of the end cap. The end cap comprises an exterior contact surface that faces away from the implant body when positioned on the base section, a seating surface which contacts the base section when positioned on the implant body, an end cap angulation, and locking passages extending between the exterior contact surface and seating surface and adapted to receive base section teeth. The locking passages and base teeth are complimentarily configured to engage and securely maintain the end cap positioned on the base section such that the implant imparts the end cap angulation to an adjacent vertebral body at a selected point when the implant is positioned between adjacent vertebral members.Type: GrantFiled: October 22, 2009Date of Patent: May 15, 2012Assignee: Warsaw Orthopedic, Inc.Inventors: Jonathan Blackwell, Thomas E.

Publication number: 20120016478Abstract: Implants sized to be inserted into an intervertebral space between first and second vertebral members, and related methods. The spinal implant may have a body extending along a longitudinal axis with opposing first and second longitudinal ends. An end cap is mounted to the body at one of the ends and disposed longitudinally outboard of the corresponding end. The end cap comprises a first portion, a second portion, and an annular elastic element, such as an O-ring. The first and second portions are disposed circumferentially around the longitudinal axis. The annular elastic member circumferentially surrounds the first portion, the second portion, and the longitudinal axis. The annular elastic member applies a compressive force that urges the first and second portions together in a direction transverse to the longitudinal axis. The end cap may be flat or angled. Other implants and related methods are disclosed.Type: ApplicationFiled: July 15, 2010Publication date: January 19, 2012Applicant: Warsaw Orthopedic, Inc.Inventors: Bret M. Wilfong, Michael J. Merves

Publication number: 20120016476Abstract: Devices and methods for spacing apart vertebral members. The implant may include a body and an end cap. Connectors may extend outward from the body to attach with the end cap. The end cap may include a hinged design to securely attach to the body. The hinged design may include first and second sections that are connected at a hinge. The implant may also include a second end cap positioned at the opposite end of the body. The second end cap may be the same or different than the first end cap.Type: ApplicationFiled: July 15, 2010Publication date: January 19, 2012Applicant: Warsaw Orthopedic, Inc.Inventors: Bret M.
