Publication number: 20140308089Abstract: A fastening device including a fastener having a head portion and an elongated threaded body portion extending axially from the head portion. The threaded body portion includes opposing flat sections. A lock washer has a lower surface with an array of radially extending engagement teeth. The lock washer also defines an axial aperture for receiving the fastener. The axial aperture has two flat inner surfaces for cooperating with the two flat sections of the threaded body portion to prevent relative rotation of the washer and threaded body portion. A threaded lock nut mates with the threaded body portion. The lock nut has an upper surface with at least one cantilevered pawl members for ratcheted engagement with the array of radially extending engagement teeth of the lock washer.Type: ApplicationFiled: June 30, 2014Publication date: October 16, 2014Inventor: Harold Hess

Patent number: 8814915Abstract: A vertebral column construct for stabilizing a segment of a vertebral column can include first and second plate segments, and a spring connected between adjacent plate segments. The spring can be adapted and configured to provide a predetermined preload between the first and second plate segments. Such a preload can advantageously enhance fusion across a bone graft. Alternatively, the spring can be adapted and configured to resist, by a predetermined degree, loading between the first and second plate segments. A cam can be provided on one of the first and second plate segments, wherein engagement between the cam and the cam surface prevents dynamic connection between the first and second plates. The cam can be adapted and configured to adjust a preload applied between segments, such as by adjusting tension in the spring.Type: GrantFiled: August 17, 2012Date of Patent: August 26, 2014Assignee: Spinal Simplicity LLCInventors: Harold Hess, Todd Moseley, Melissa Frock

Publication number: 20130304067Abstract: A bone fracture plate assembly including female and male plate portions. The female plate portion has a post, a female dovetail, and an extending aim with a group of ratchet teeth. The male plate portion has two upstanding posts, a male dovetail for coupling to the female dovetail so that the plate portions move linearly with respect to each other, a slot for the arm, and a pawl for engaging the ratchet teeth. A spring, coupled to the posts of the plate portions, dynamically connects the plate portions by applying a compressive load therebetween. The spring has a pair of elongated ears, each defining a slot to allow for relative movement of the plate portions. The ratchet teeth are engaged by the pawl to retain the plate portions together, and the spring mounts on the posts of the plate portions such that the spring biases the plate portions together.Type: ApplicationFiled: May 10, 2013Publication date: November 14, 2013Inventors: Harold Hess, Melissa Frock, Adam Frock, Adam Rogers, Todd Moseley, Jonathan Hess, Paul Sand, Carlos Gonzalez

Patent number: 8523909Abstract: Spinal implants include an elongated body portion dimensioned and configured for percutaneous introduction into a target interspinous process space, at which interspinous distraction and/or spinal fusion are desired. The body portion can include a threaded outer surface, or alternatively a smooth surface. The body portion can include one or more interior cavities, and can include deployable engagement members adapted and configured to move in tandem between a stowed position retracted within the interior cavity of the body portion and a deployed position extended from the interior cavity of the body for engaging adjacent spinous processes. An internal drive assembly for selectively moving the engagement members from the stowed position to the deployed position can be provided, as can a elements for locking the engagement members in a deployed position.Type: GrantFiled: February 22, 2012Date of Patent: September 3, 2013Assignee: Spinal Simplicity LLCInventor: Harold Hess
