Patent number: 8435265Abstract: A vertebra implant is provided that includes an elongate body with a first end configured to mate the first end to a first location on a vertebra, and a second end having at least one fastener configured to mate the second end to a second location on a vertebra. The elongate body also includes a deformable portion extending between the first and second ends that has an unexpanded configuration in which the deformable portion is configured to allow a tool to cut bone extending between the first and second ends when the first and second ends are mated to first and second locations on a vertebra, and an expanded configuration in which the deformable portion is deformed to increase a distance between the first and second ends such that a gap is created in the cut bone. The deformable portion is configured to maintain the first and second ends at a fixed distance apart when the deformable portion is in the expanded configuration.Type: GrantFiled: March 18, 2009Date of Patent: May 7, 2013Assignee: DePuy Spine, Inc.Inventors: David D.

Publication number: 20110190827Abstract: Various spinal plating systems for use in treating spinal pathologies are provided. In certain exemplary embodiments, the spinal plating systems can be configured to allow a surgeon to select a bone screw construct having a particular range of motion for attaching a spinal plate to bone as needed based on the intended use. In one exemplary embodiment, the spinal plating system includes a first bone screw that is polyaxially movable relative to the spinal plate, and a second bone screw that has a range of motion that is substantially limited to a single plane.Type: ApplicationFiled: March 16, 2011Publication date: August 4, 2011Applicant: DEPUY SPINE, INC.Inventors: David D.

Patent number: 7981142Abstract: 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 bi-directional attachment to one another.Type: GrantFiled: August 9, 2005Date of Patent: July 19, 2011Assignee: DePuy Spine, Inc.Inventors: David D.

Publication number: 20080125759Abstract: An implantable drug delivery system includes an infusion pump assembly with a fluid outlet, a fluid delivery pathway extending from the pump outlet to a target tissue site; and a controlled release material unit positioned in the fluid delivery pathway to release a drug or bioactive material into the delivery pathway. The pump assembly delivers fluid as a high flow infusion flow in said pathway, entraining drug material released by the release unit and establishing a pressure gradient at the distal end of the pathway that results in convection-enhanced transport such that the released drug(s) or treatment material enter the target tissue site with enhanced penetration depth and/or concentration. The pump delivers a carrier fluid that may reside in an external or in an implanted reservoir, or that may be an endogenous fluid, such as plasma or CSF.Type: ApplicationFiled: February 1, 2008Publication date: May 29, 2008Applicant: CODMAN & SHURTLEFF, INC.Inventors: David D.

Patent number: 7108680Abstract: A delivery system for a drug or bioactive agent includes an implantable pump and a delivery conduit that may be implanted in an organ or other tissue (e.g., the central or the peripheral nervous system) of a subject. A sensor is also implanted, and a controller unit receives the sensor output and directs drug delivery from within the patient pump accordingly. The sensor directly measures a primary biochemical material or state in the tissue or organ system, and the monitoring unit effects closed loop feedback control of the pump to achieve a desired end. The end may be the regulation of metabolism or maintenance of a stable metabolic or other state, or may be treatment regimen, e.g., by delivery of a dosage level or distribution of a drug in specific brain or nervous an system tissue. The sensed material may be the agent itself, a metabolite, or a related native material, tissue state or condition.Type: GrantFiled: March 6, 2002Date of Patent: September 19, 2006Assignee: Codman & Shurtleff, Inc.Inventors: William L.
