Patent number: 9351767Abstract: A spinal implant provides supplemental and dynamic fixation and/or stabilization of the spine via connection to one or more existing or new spinal fixation and/or stabilization spinal constructs. The supplementary spinal fixation/stabilization implant has a first attachment device configured to couple to an existing or new spinal fixation/stabilization construct and a second attachment device configured to couple to the existing or new spinal fixation/stabilization construct at a second location. The first and second attachment devices are joined to each other via a resilient connector that allows dynamic movement between the first and second attachment devices.Type: GrantFiled: March 24, 2010Date of Patent: May 31, 2016Assignee: Life Spine, Inc.Inventor: Thomas J.

Patent number: 9095386Abstract: A spinal rod guide and/or guide assembly is provided for mounting a spinal rod onto a spinal rod holder/connector of a vertebral bone screw. The spinal rod guide is configured to extend between an opening in a patient's body and the spinal rod holder of the vertebral bone screw assembly, to receive a spinal rod therein, and thereafter accurately guide the spinal rod into the spinal rod holder. The spinal rod guide is defined by a first elongated arc portion and a second elongated arc portion to define a guide tube for the introduction and placement of additional spinal rod components onto the spinal rod connector, particularly, but not necessarily, for securing the spinal rod into the spinal rod connector. The elongated arc portions are mountable or initially attached onto a top of a spinal rod holder of a spinal rod bone screw assembly. The elongated arc portions (tube) define first and second longitudinal slots extending from a top of the elongated arc portions to a bottom of the elongated arc portions.Type: GrantFiled: March 21, 2009Date of Patent: August 4, 2015Assignee: Life Spine, Inc.Inventors: Michael S. Butler, Brian D. Hartsell, Thomas J. Wegrzyn, III

Patent number: 8764754Abstract: A guide assembly includes a spinal screw assembly having a bone screw and a spinal rod holder; and a spinal rod guide having first and second elongated arc portions defining a pair of longitudinal slots extending along the first and second arc portions, each of the first and second arc portions further defining at least one recess extending transversely from each of the longitudinal slots, the at least one recess configured to receive at least a portion of a reduction tool to enable reduction of a spinal rod received within the spinal rod holder.Type: GrantFiled: January 28, 2011Date of Patent: July 1, 2014Assignee: Life Spine, Inc.Inventors: Michael S. Butler, Brian D. Hartsell, Thomas J. Wegrzyn, III

Patent number: 8224448Abstract: A feedthrough assembly is disposable in an aperture of, for example, a power source encasement. In various examples, the feedthrough assembly comprises a ferrule, an insulator, a terminal conductor, and a sleeve. A portion of the terminal conductor extends through the ferrule thereby creating a portion internal to and a portion external to the encasement. The insulator is disposed within the ferrule and is sealably engaged with the terminal conductor portion extending through the ferrule. The sleeve is disposed over the internal portion of the terminal conductor and coupled thereto. In one example, the sleeve includes at least one notch on a sleeve first end or a sleeve second end, which may be used to weld or solder the sleeve to the terminal conductor. In another example, the sleeve includes a longitudinally extending void, which may be used to crimp the sleeve to the terminal conductor.Type: GrantFiled: April 16, 2009Date of Patent: July 17, 2012Assignee: Cardiac Pacemakers, Inc.Inventors: Thomas J. Wegrzyn, III, Edward J. Maierhofer, James P. Rohl, Stephen W. VanDerlick, Benjamin J. Haasl

Publication number: 20100256765Abstract: A spinal implant and method of implant use are provided for application about a spinal implant area. The spinal implant is formed of a resilient and/or elastic covering, and first and second bone fasteners for holding the covering in place. An all-in-one deployment instrument is also provided that delivers and installs the spinal implant to the spinal implant site. The spinal implant provides a covering for the spinal implant site such as a spinal disc fissure, about a portion of a spinal disc after a full or partial discectomy or other procedure, and/or over any spinal disc area. The covering is disposed between and held by the first and second bone fasteners. An application instrument for introducing and installing the present spinal implant is also provided. The instrument introduces then applies the covering at the spinal implant site and drives the vertebral body staples into the vertebral body to secure the covering to the spinal implant site.Type: ApplicationFiled: April 1, 2010Publication date: October 7, 2010Inventors: Michael S. Butler, Thomas J. Wegrzyn, III

Publication number: 20090318970Abstract: A spinal rod connector is configured to accommodate a range of spinal rod diameters. The present spinal rod connector may take the form of a spinal rod screw head, hook, spinal rod connector or a spinal rod holder. The spinal rod connector has spinal rod reception slots whose sides narrow towards a bottom of the slot. The narrowing of the sides provides a wedging effect such that a spinal rod is wedged into place during locking. The narrowing sides of the slots thus provide for the accommodation of varying rod diameters. The spinal connector also provides significant improvement in spinal rod torsional resistance compared to prior art radial shaped slots. In one form, the spinal rod reception slots are essentially V-shaped. However, other shapes following the principles of the present invention may be used and are contemplated.Type: ApplicationFiled: June 19, 2009Publication date: December 24, 2009Inventors: Michael S. Butler, Thomas J. Wegrzyn III
