The supports can be attached to vertebrae with pedicles screws, and/or other anchors attached to the supports.Type: GrantFiled: February 4, 2008Date of Patent: July 16, 2013Assignee: SpinalMotion, Inc.Inventors: Malan de Villiers, David Hovda

Patent number: 8486077Abstract: A method, tools, and system for performing a percutaneous or minimally invasive spine fusion procedure are provided. A trocar and then dilator are used to create a channel for a hollow and longitudinally slit delivery tube. The method includes inserting a decorticator, such as a rasp, via a delivery tube, decorticating a first region of a first bone associated with a spine, and pushing a bone fusion substance via the delivery tube to the region to fuse the first region with a second region of a second bone associated with the spine. The spine fusion may be a posterolateral fusion and the first region may be a transverse process region of a lumber spine. The bone fusion substance may be pushed using a pusher instrument inserted into the delivery tube, and the delivery tube may be removed while the pusher instrument is held in place to direct the bone fusion substance.Type: GrantFiled: January 5, 2007Date of Patent: July 16, 2013Inventor: Ezriel E. Kornel

Patent number: 8475461Abstract: Instruments are provided for delivering and installing a multi-section spinal implant in-situ one section at a time by sequential deployment and assembling of the multi-section spinal implant sections into an intervertebral space. An advancement mechanism provides controlled deployment of individual implant sections from the instrument. Each instrument accepts a plurality of implant sections that are stacked on a deployment rod. Activation of the advancement mechanism advances a pusher against a rearward implant section of the implant section stack. This, in turn, advances all or some of the implant sections such that the forward most implant section exits the instrument. As the advancement mechanism is further activated, additional implant sections are deployed from the instrument. In this manner, a multi-section spinal implant of any number of implant sections may be delivered and assembled in situ. In one form, the advancement mechanism comprises an indexing mechanism.Type: GrantFiled: June 9, 2010Date of Patent: July 2, 2013Assignee: Life Spine, Inc.Inventors: Michael S. Butler, Brian D. Hartsell

Patent number: 8425531Abstract: An electronically guided spinal rod system for the placement of a spinal rod into the heads of pedicle screws and other types of bone fixation systems includes a bone screw inserter having rod access slots extending longitudinally for a length along the screw inserter, a rod detection system coupled to the rod access slots and a rod pusher for inserting a spinal rod through the rod access slots. The electronically guided spinal rod system insures that the spinal rod will be accurately positioned while allowing the operator complete freedom to choose its specific path into the screw inserter rod access slots.Type: GrantFiled: May 25, 2010Date of Patent: April 23, 2013Inventor: Anthony Salerni

Patent number: 8382767Abstract: An insertion tool for placing a spinal implant in an intervertebral space includes a handle assembly, a jaw assembly having first and second jaw members movable with respect to each other, and a holding member adapted to hold and release an implant in response to a manipulation of the handle assembly. The holding member is configured to move longitudinally with respect to the jaw assembly upon manipulation of the handle assembly.Type: GrantFiled: November 2, 2009Date of Patent: February 26, 2013Assignee: K2M, Inc.Inventors: Adam Wassinger, Todd Wallenstein

Patent number: 8372115Abstract: A bone support and/or barrier device and having an implantable structure including an outer surface, an inner surface, a first bone contact portion, and a second bone contact portion. The structure is collapsible to an undeployed configuration capable of percutaneous insertion to the interior of a bone and expandable to a deployed configuration in the bone. In the deployed configuration, the first bone contact portion contacts a first portion of the bone, and the second bone contact portion contacts a second portion of the bone such that a load placed on the first portion of the bone is transferred through the implantable structure to the second portion of the bone. The implantable structure includes a barrier material adapted to restrict bone filler material inserted into the bone adjacent the inner surface of the structure from flowing to the outer surface of the structure. A method is also disclosed.Type: GrantFiled: September 13, 2011Date of Patent: February 12, 2013Assignee: Kyphon SARLInventors: Andrew Kohm, Janna Clark, Samuel Lee, Thomas A. Slater

Patent number: 8366714Abstract: An insertion tool for inserting a spinal rod into a patient is provided. The insertion tool includes an upper body portion defining a first longitudinal axis, a handle assembly extending from the upper body portion, an elbow member connected to a distal end of the body portion, a lower body portion defining a second longitudinal axis, and a drive mechanism extending between the handle assembly and the lower body portion for controlling the selective engagement of the spinal rod. The lower body portion extends from the elbow and is configured to selectively engage a spinal rod.Type: GrantFiled: October 23, 2008Date of Patent: February 5, 2013Assignee: K2M, Inc.Inventors: Scott Jones, Catherine Ross

Patent number: 8343160Abstract: A medical inserter tool is provided for introducing medical implants into a surgical site, preferably using minimally invasive techniques. The inserter tool can have a variety of configurations, but in general, the inserter tool should be effective to engage and manipulate the implant into two or more positions. In an exemplary embodiment, the tool includes an elongate shaft having proximal and distal ends and defining a longitudinal axis extending therebetween, and a pivoting element that is coupled to the distal end of the shaft and that is adapted to engage a spinal implant. In use, the pivoting element is movable between first and second positions to allow an implant to be introduced through a percutaneous access device in a lengthwise orientation, and to be manipulated subcutaneously to be positioned in a desired orientation.Type: GrantFiled: December 15, 2009Date of Patent: January 1, 2013Assignee: DePuy Spine, Inc.Inventors: Richard C. Techiera, Sean P. Selover

Patent number: 8333770Abstract: The present application is directed to various spinal stabilization systems. The systems can include one or more guiding elements attached to screw members to assist in guiding rod implants and tools to desired locations within a patient. The guiding elements can include a plurality of wires, blades, or tabs. The guiding elements can be capable of criss-crossing or intersecting at or near an incision, such that only a single incision may be needed to perform a surgery. The guiding elements can also include telescoping features that allow the height of the guiding elements to be adjusted in use, thereby allowing multiple telescoping guiding elements to be used with the same incision.Type: GrantFiled: September 26, 2011Date of Patent: December 18, 2012Inventor: Sherwin Hua

Patent number: 8317801Abstract: The present invention describes a targeting system suitable for guiding a biocompatible device to a target area within the body (in vivo) and method of using the same. The system includes a targeting member that is attached to the biocompatible device and may optionally include a steering material. The system includes a passer element located at the distal end of a wand. The wand includes a trigger like member adjacent a hand grip. Actuation of the trigger like member will result in a pivotal movement of the passer element that positions the targeting member such that the connected biocompatible device is positionable relative to the target area.Type: GrantFiled: December 7, 2011Date of Patent: November 27, 2012Assignee: Magrod, LLCInventors: Wyatt Drake Geist, Christopher Walsh
