Patent number: 9168033Abstract: A spinal implant for treating lumbar spinal stenosis or as an adjunct to spinal fusion. The implant includes a body portion having an interior cavity. A plurality of locking wings are adapted and configured to move 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 portion. In the deployed position, the wings fix the implant in a selected interspinous space. A cable and wheel arrangement moves the plurality of locking wings from the stowed position to the deployed position and a ratchet/pawl assembly prevents backward movement of the wings.Type: GrantFiled: December 2, 2011Date of Patent: October 27, 2015Assignee: Spinal Simplicity LLCInventor: Harold Hess

Publication number: 20150216570Abstract: A bone fracture plate assembly including female and male plate portions. The female plate portion has a post, a female dovetail, and an extending arm 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: February 3, 2015Publication date: August 6, 2015Applicant: Spinal Simplicity LLCInventors: Harold Hess, Melissa Frock, Adam Frock, Adam Rogers, Todd Moseley, Jonathan Hess, Paul Sand, Carlos Gonzalez

Publication number: 20140371795Abstract: An interspinous process implant comprising an elongated body defining a longitudinal axis and an interior cavity. The implant includes engagement members movable between a first position stowed within the interior cavity and a second position deployed from the interior cavity. Each engagement member includes a central hub defining a hub axis perpendicular to the longitudinal axis of the body. Each central hub has an inwardly extending crank pin. The crank pins are radially offset from the hub axis and circumferentially spaced apart from one another. The implant also include an elongated drive shaft mounted for axial movement within the interior cavity and includes a distal actuation portion having upper and lower yokes positioned to cooperate with the crank pins. Upon axial movement of the drive shaft the crank pins translate through respective arcuate paths about the hub axis, causing corresponding rotational movement of the engagement members about the hub axis.Type: ApplicationFiled: June 13, 2014Publication date: December 18, 2014Applicant: Spinal Simplicity LLCInventors: Harold Hess, Todd Moseley, Melissa Frock, Adam Rogers

Publication number: 20140358186Abstract: An insertion device for deploying an implant includes an elongated main body having a distal locking portion for coupling to the implant and a proximal handle portion. The main body defines a central passage and the distal locking portion has outer ridges and slots to allow the outer ridges to flex radially inward when mounting to the implant. A plunger slides in the central passage for movement between an unlocked position for mounting the implant on the distal locking portion, a locked position for locking the implant on the distal locking portion, and an insertion instrument deployed position for deploying the actuation plunger to move the blades from the stowed position to the deployed position. A spike cap drive rotatably mounts on the main body having a socket end for engaging a drive nut on the implant to, in turn, move the spike cap.Type: ApplicationFiled: May 29, 2014Publication date: December 4, 2014Applicant: SPINAL SIMPLICITY LLC.Inventors: Melissa Frock, Adam Frock

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
