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

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

Publication number: 20120150229Abstract: 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: ApplicationFiled: February 22, 2012Publication date: June 14, 2012Applicant: SPINAL SIMPLICITY LLCInventor: Harold Hess

Publication number: 20120078301Abstract: 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: ApplicationFiled: December 2, 2011Publication date: March 29, 2012Applicant: Spinal Simplicity LLCInventor: Harold Hess
