Patent number: 8870956Abstract: A fusion implant apparatus for facilitating fusion of adjacent bone structures includes a threadless implant member which is positioned between adjacent opposed bone structures. The implant member defines a longitudinal axis and first and second longitudinal ends and has an outer wall which is dimensioned to engage the opposed bone structures upon positioning therebetween in supporting relation therewith. The outer wall defines an internal cavity for the reception of bone growth inducing substances and includes a plurality of apertures which extend therethrough in communication with the internal cavity to permit fusion of vertebral bone tissue. The implant member also includes an intermediate portion which defines a cross-sectional dimension transverse to the longitudinal axis which is greater than the respective cross-sectional dimensions of the first and second longitudinal ends of the implant member.Type: GrantFiled: January 7, 2005Date of Patent: October 28, 2014Assignee: Howmedica Osteonics Corp.Inventors: Jared Walkenhorst, Herb Cohen, Lance Middleton

Patent number: 7303584Abstract: A method for facilitating fusion of bone structures includes providing an implant member for positioning between opposed bone structures, the implant member having a first end and a second end, and a segmentable portion having an outer wall defining an internal cavity for reception of bone growth inducing substances. The outer wall has at least one groove which extends substantially continuously about the outer wall to define a plurality of discrete ring-like segments. Each ring-like segment includes a plurality of apertures extending therethrough in communication with the internal cavity to permit fusion of vertebral bone tissue. The vertebral space defined between adjacent vertebral bodies is accessed, and the desired implant member length for insertion into the space between adjacent vertebral bodies is determined. The implant member is cut to the desired length and advanced within the vertebral space between the adjacent vertebral bodies.Type: GrantFiled: April 22, 2005Date of Patent: December 4, 2007Assignee: Howmedica Osteonics Corp.Inventors: Michael Castro, Herb Cohen, David Nichols, R.
