Patent number: 9320552Abstract: Methods and devices are provided for passively locking a bone screw within a bone plate. In particular, the methods and devices allow a bone screw to be locked within a thru-hole in a bone plate without requiring any additional locking steps. In an exemplary embodiment, an annular feature is provided in a thru-hole of a bone plate, or in a bushing that is disposed within a thru-hole of a bone plate, for engaging a bone screw. The annular feature can be configured such that it allows the bone screw to be inserted through the thru-hole at various insertion angles while still being effective to prevent back-out of the bone screw, thereby locking the screw to the plate.Type: GrantFiled: March 10, 2014Date of Patent: April 26, 2016Assignee: DePuy Synthes Products, Inc.Inventors: Michael Jacene, Jonathan Fanger, John R. Hawkins

Patent number: 9155569Abstract: 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: April 11, 2013Date of Patent: October 13, 2015Assignee: DePuy Synthes Products, Inc.Inventors: David D.

Patent number: 8931158Abstract: A liner and method of application for use on a metal surface to protect metal structures such as cooling towers, evaporative condensers, and other liquid containing vessels such as tanks from corrosion, leaks, and wear. The liner is an inexpensive apparatus and process comprising a coated metal having a second sealing and bonding layer and a third protective sealing layer. The liner method comprises applying an organic bonding layer onto the galvanized substrate, and applying an elastomeric barrier coating to the bonding layer. The barrier coating material is applied to preseal the seams between adjoining panels assembled to form the basin. The barrier coating is applied to the entire inside of the basin to form a homogenous barrier coating extending out of the basin. The liner edge is isolated from the basin by extending the liner to a point between the basin and an upper section.Type: GrantFiled: January 25, 2011Date of Patent: January 13, 2015Assignee: Baltimore Aircoil Company, Inc.Inventors: Frank T. Morrison, Greg M. Lowman, John R. Hawkins, James W. Furlong

Patent number: 8715352Abstract: An artificial disc replacement implant is provided that includes an implantable body having a superior surface adapted to be positioned adjacent to an endplate of a superior vertebra, and an opposite inferior surface adapted to be positioned adjacent to an endplate of an adjacent inferior vertebrae. The implantable body includes at least one wall formed therein and extending between the superior and inferior surfaces. The wall(s) can be adapted such that, when the implantable body is disposed between the endplates of adjacent superior and inferior vertebrae, the wall(s) will buckle by moving laterally and shorting in height under a load applied thereto by movement of the adjacent vertebrae. The implantable body can also include at least one opening formed adjacent to the wall(s) and extending between the superior and inferior surfaces of the implantable body.Type: GrantFiled: December 14, 2006Date of Patent: May 6, 2014Assignee: DePuy Spine, Inc.Inventors: Erasmo Lopez, SeungKyu Daniel Kwak, Amie Borgstrom, John R.
