Publication number: 20120226284Abstract: A vertebral distractor system includes a crossbar and a first distractor arm having a first end portion coupled to the crossbar and a second end portion with a first bore configured to axially receive a first coupling portion of a first pin. A second distractor arm includes a third end portion coupled to the crossbar and a fourth end portion with a second bore configured to receive a second coupling portion of a second pin. A first pin locking mechanism is configured to couple the first coupling portion and the first distractor arm within the first bore such that when the first coupling portion and the first distractor arm are coupled, movement of the first pin outwardly of the first bore is not allowed.Type: ApplicationFiled: May 17, 2012Publication date: September 6, 2012Applicant: DEPUY SPINE, INC.Inventors: Michael Sorrenti, Douglas Raymond, David Konieczynski, Ed Zalenski, Conor McCrea

Patent number: 8021428Abstract: A prosthetic is provided for replacing a vertebral disc. The prosthesis can comprise first and second endplates formed of a ceramic material, each including an articulating contact surface and a bone facing surface. The contact surface of the first endplate can have a shape complementary to the contact surface of the second endplate, thereby facilitating articulation of the first and second endplates while in contact with one another. The device can further include at least one non-ceramic bone attachment element mated with at least one of the bone facing surfaces, such that the bone attachment element covers less than a full area of the bone facing surface.Type: GrantFiled: May 25, 2005Date of Patent: September 20, 2011Assignee: DePuy Spine, Inc.Inventors: Charles M. Bartish, Jr., Jeffrey Brousseau, Patrick Fatyol, Conor McCrea, Michael J. O'Neil, Stephen Connolly

Patent number: 7708766Abstract: A simple, safe implantable bone screw, and a method for distracting two bone segments, is provided. In general, the bone screw includes a shank having a threaded proximal portion and a distal portion with a major diameter that is less than a minor diameter of the threaded proximal portion. A transitional region of decreasing diameter can be disposed between the threaded proximal portion and the distal portion, and a driver receiving element is preferably disposed on a proximal end of the bone screw. In use, the proximal and distal portions of the bone screw are adapted to engage two segments of bone, and to create a distraction force between the two segments of bone.Type: GrantFiled: August 11, 2003Date of Patent: May 4, 2010Assignee: DePuy Spine, Inc.Inventors: David Greg Anderson, Conor McCrea, Christopher Ramsay

Publication number: 20040267275Abstract: An implant holder is provided having first and second gripping arms, each having a proximal portion with a mating element formed thereon for selectively mating to a medical device, and a distal portion adapted to at least partially circumferentially engage and axially align with a rod-receiving member, e.g., a head, of a spinal implant. The spinal implant holder further includes an actuator mechanism coupled to the first and second gripping arms and effective to move the gripping arms between an open position, in which the gripping arms can be positioned around the rod-receiving head of a spinal implant, and a closed position, in which the gripping arms engage the rod-receiving head of the spinal implant. A rod reduction device is also provided and includes an elongate inserter tool having a proximal end and a distal end with a fastener-retaining member formed thereon and adapted to retain a fastener therein.Type: ApplicationFiled: June 26, 2003Publication date: December 30, 2004Inventors: John R. Cournoyer, Carl G. Souza, Anthony R. Carlone, Michael S. Varieur, Conor McCrea, Stephen Johnson
