Patent number: 8747441Abstract: Bone screws and bone plates are provided that offer the surgeon the ability to either assemble the screws to the plate, or the plate to the screws, depending on the surgeon's preference and the patient's circumstances. The bone screws and bone plates of the present invention include a combination of geometric configurations that allow the screws and plates to fit together from different assembly directions. Additionally, the bone screws and bone plates can include material resilience features to allow expansion/contraction during assembly to allow bidirectional attachment to one another.Type: GrantFiled: February 24, 2011Date of Patent: June 10, 2014Assignee: DePuy Spine, Inc.Inventors: David D. Konieczynski, Thomas V. Doherty, Alexander D. Grinberg, Eric D. Kolb

Patent number: 8177800Abstract: A method for removing a vein includes making an incision through a skin layer of a patient, inserting a surgical instrument through the incision, visualizing the vein through the skin layer using a light source positioned subcutaneously and in proximity of the vein, and cutting the vein using the surgical instrument. The vein can be visualized by directing light from the light source at the vein from underneath the vein or from a side of the vein. A device for illuminating a body structure has a housing with a distal end configured for subcutaneous insertion into a patient's tissue and positioning in proximity of the body structure, a light path supported by the housing and configured for directing light at the body structure, and a fluid line supported by the housing.Type: GrantFiled: February 24, 2006Date of Patent: May 15, 2012Assignee: InaVein LLCInventors: Gregory A. Spitz, Douglas D. Sjostrom, Alexander D. Grinberg, Michael A. Long

Patent number: 7867279Abstract: An intervertebral disc prosthesis comprises a first plate including a socket and a second plate comprising a recess. A core is sandwiched between the socket and the recess. The core includes a domed surface and a plug portion. The first plate is configured to rotate upon the domed surface of the core. The second plate is substantially fixed to the core, with the plug portion engaging the recess. The core may be press-fit into the second plate during assembly of the intervertebral disc prosthesis. The first plate and second plate both include tabs that define notches, wherein the notches are configured to engage prongs of a disc insertion tool. Teeth provided on the first plate and the second plate assist in fixing the first plate and the second plate to the vertebral bodies.Type: GrantFiled: January 23, 2006Date of Patent: January 11, 2011Assignee: DePuy Spine, Inc.Inventors: Douglas L. Hester, Paul S. Maguire, Alexander D. Grinberg

Patent number: 7341591Abstract: An anterior buttress staple and screw system is provided that can be used to hold an implant such as a disc prosthesis in place and thereby prevent its migration out of the spinal column. The buttress staple comprises a screw locking plate having a screw locking design that prevents the screw from backing up and away from the plate. The screw is configured to provide an interference fit with the screw locking plate, and can be used as a staple removal tool during revision surgery when the screw locking plate needs to be lifted from the bone surface on which it is attached.Type: GrantFiled: January 30, 2003Date of Patent: March 11, 2008Assignee: DePuy Spine, Inc.Inventor: Alexander D. Grinberg

Patent number: RE43317Abstract: An installation tool that is useful for the efficient and effective placement of an article, such as an artificial disc, between adjacent vertebral bodies is provided. The installation tool can be provided as a kit having modular components which allow the surgeon to select from among a variety of components to assemble an installation tool that is optimized for its intended use. The installation tool of the invention generally includes a pair of opposed levers, each of which has a proximal handle portion and a distal portion. A fulcrum is disposed between the two levers to enable proper operation of the tool. The tool further includes a pusher block that is positioned between the two levers and is selectively movable between an initial location distal of the fulcrum and a final location adjacent the distal end of the levers. The pusher block includes a proximal end, a distal end, and a bore extending at least partially therethrough.Type: GrantFiled: March 29, 2006Date of Patent: April 17, 2012Assignee: DePuy Spine, Inc.Inventors: Robert D. Fraser, Alexander D. Grinberg, John D. Malone, Bradley Moore, Michael J. O'Neil, Mark C. Boomer
