Patent number: 8512344Abstract: A medical instrument apparatus and method is provided to insert and release medical implants. This invention pertains generally to medical instruments and more specifically to spinal implant insertion instruments for spinal fixation systems. The insertion instrument may provide a positive locking and unlocking actuator, preferably in the form of a lever, which ensures that the pedicle screw and yoke assembly is either mechanically locked to the insertion instrument or unlocked to the insertion instrument. The positive locking and unlocking actuator of the insertion instrument eliminates guesswork for the surgeon because the surgeon can readily know if the pedicle screw and yoke assembly is attached to the insertion instrument or not. Superelastic components may also be included to shift components in a first direction and pull components under superelastic tension in a second direction for increased holding force.Type: GrantFiled: April 14, 2009Date of Patent: August 20, 2013Assignee: Pioneer Surgical Technology, Inc.Inventors: Jeffrey A.

Patent number: 8343165Abstract: A driver apparatus for implanting spinal rod fixation devices including an anchor member and a coupling member pivotable relative to the anchor member is disclosed. The driver apparatus generally immobilizes the anchor member and coupling member relative to each other and to the driver apparatus during insertion to minimize interference between the coupling member and tissues surrounding the implantation site, as well as to minimize the clearance required for implantation. The driver apparatus includes a driver portion engageable with the anchor member for effecting seating of the anchor member, such as by threadably driving the anchor member in the bone. The driver portion is closely fit between portions such as upstanding walls of the coupling member to prevent relative rotation therebetween. The driver apparatus further includes locking portions shiftable to secure the coupling member with the driver apparatus when the driver is engaged with the anchor member.Type: GrantFiled: September 26, 2006Date of Patent: January 1, 2013Assignee: Pioneer Surgical Technology, Inc.Inventor: Gregory Berrevoets

Patent number: 8262731Abstract: Artificial disc devices are disclosed that restore correct anatomical intervertebral spacing for damaged discs while maintaining a substantially normal range of biomechanical movement for the vertebrae between which they are implanted. The disc devices include center bearing and outer or annular bearing portions with the center bearing portion including generally axially extending locating surfaces which cooperate with the facing vertebral surfaces to resist migration. The outer bearing portion is for load bearing or load sharing with the center bearing portion and includes surfaces that extend radially toward the periphery of the vertebrae so that subsidence about the center bearing portion is minimized. Alternate forms of the disc devices include one with an axially enlarged center ball bearing having an annular ring bearing extending thereabout and another having upper and lower plate members with a central bumper member and a surrounding resilient annular member therebetween.Type: GrantFiled: July 19, 2005Date of Patent: September 11, 2012Assignee: Pioneer Surgical Technology, Inc.Inventors: Matthew N. Songer, Thomas S. Kilpela, Brian P. Janowski, Gregory A. Berrevoets, Matthew P. Gephart

Patent number: 8235997Abstract: Instruments and methods are provided for securing a spinal rod in one or more coupling devices secured to the spine by one or more anchor members. The instruments include members for grasping the coupling device and members for shifting one or more elements along a linear path to fix the position of an anchor member and/or fix the position of the rod with respect to the vertebra.Type: GrantFiled: January 29, 2009Date of Patent: August 7, 2012Assignee: Pioneer Surgical Technology, Inc.Inventors: Jeffrey Hoffman, Joseph Mohar, Maria M.

Patent number: 8172885Abstract: Bone plate and bone screw lock systems are provided for use in surgical implants. In a preferred form, the bone plate or other implantable member defines a bore for receiving a bone screw and a recess in communication with the bore. A screw lock operates in the bore at the recess to engage and lock the bone screw against unintentional movement. The preferred screw lock is shifted about the screw between an unlocked position to allow manipulation of the screw and a locked position in which the screw lock grips the head of the screw to prevent movement of the screw. The screw lock preferably has a c-shaped collar configuration with opposing ends and a camming engagement with the plate or other member in the recess. Upon rotation of the screw lock, the camming engagement causes the ends of the collar to either shift toward one another in which the collar compresses about the screw to lock the screw or away from another to unlock the screw head.Type: GrantFiled: February 5, 2004Date of Patent: May 8, 2012Assignee: Pioneer Surgical Technology, Inc.Inventors: Matthew N. Songer, Hansen Yuan, Thomas S. Kilpela, Brian P. Janowski, Gregory A. Berrevoets
