Patent number: 9295494Abstract: A spinal stabilization system includes a connecting rod, a rod bending device, and a plurality of bone screws. The connecting rod includes an elongate round portion, an elongate head portion and a neck portion connecting the elongate round portion with the elongate head portion. The rod bending device includes an elongate body defining an aperture configured and dimensioned to receive the connecting rod therethrough in a single orientation. The bone screws include a housing portion and a screw shaft distally extending from the housing portion. The housing portion includes an inner housing and an outer housing slidably surrounding at least a portion of the inner housing. The inner housing defines a slot configured and dimensioned to releasably secure the elongate round portion of the connecting rod therein. The outer housing is movable relative to the inner housing between an unlocked state and a locked state.Type: GrantFiled: June 28, 2011Date of Patent: March 29, 2016Assignee: K2M, Inc.Inventors: Kevin R. Strauss, Scott Jones, Jennifer Moore, Michael Barrus, Oheneba Boachie-Adjei, Robert Clinton Boyd

Patent number: 9186184Abstract: A spinal fixation system is provided that, in one form, comprises a pedicle screw assembly having a coupling device with an elongate member for guiding a fixation element, such as a spinal rod, into the coupling device and a lock device for fixing the spinal rod to the coupling device. The pedicle screw assembly may be passed through a small incision and connected to a vertebral bone. By connecting a second pedicle screw assembly to a second vertebral bone, the elongate members of the pedicle screw assemblies provide guideposts for directing the spinal rod subcutaneously between the pedicle screw assemblies and into the coupling devices thereof.Type: GrantFiled: February 3, 2012Date of Patent: November 17, 2015Assignee: PIONEER SURGICAL TECHNOLOGY, INC.Inventor: Brian P. Janowski

Patent number: 9149304Abstract: Spinal implants for limiting flexion of the spine are implanted between a superior spinous process and an inferior spinous process or sacrum. The implants include upper straps which are placed over the upper spinous process, while the lower portions of the implant are attached to the adjacent vertebra or sacrum. The attachments may be fixed, for example using screws or other anchors, or may be non-fixed, for example by placing a loop strap through a hole in the spinous process or sacrum.Type: GrantFiled: August 2, 2013Date of Patent: October 6, 2015Assignees: The Board of Trustees of the Leland Sanford Junior University, Empirical Spine, Inc.Inventors: Todd Alamin, Ian Bennett, Louis Fielding, Colin Cahill

Patent number: 9144440Abstract: This equipment comprises at least one rigid connecting bar (2), first and second bone anchoring members (3, 4) and first and second connecting parts (5, 6), capable of connecting the connecting bar (2) to said bone anchoring members (3, 4). According to the invention, each second bone anchoring member is in the form of a flexible ligament (4) capable of being engaged around the lamina (101) or an apophysis of a vertebra (100); each second connecting part (6) comprises a conduit (11) receiving said ligament (4) and means (12) for blocking said ligament (4) in the conduit, with tensing of the ligament (4), and each contact member includes at least one rotating part (16; 17) mounted in said second connecting part (6), capable of coming into contact with said connecting bar (2) by a point.Type: GrantFiled: September 30, 2014Date of Patent: September 29, 2015Assignee: MEDICREA INTERNATIONALInventor: Afshin Aminian

Patent number: 9023026Abstract: An ablation device including a handle portion, a shaft and at least one cable. The shaft extends distally from the handle portion and includes an inner conductor and an outer conductor that substantially surrounds at least a portion of the inner conductor. The cable extends from the handle portion along at least a portion of the shaft. The distal tip of the inner conductor is positionable distally beyond a distal-most end of the outer conductor. In response to movement of the at least one cable relative to the handle portion, the distal tip of the outer conductor is movable form a first position where the distal tip is substantially aligned with a longitudinal axis defined by the outer conductor to at least a second position where the distal tip is disposed at an angle relative to the longitudinal axis.Type: GrantFiled: January 14, 2013Date of Patent: May 5, 2015Assignee: Covidien LPInventor: Mani N.

Patent number: 8979905Abstract: A spine or spinal rod has a cross-section defining angled sides that cooperate with a spinal rod opening of a spinal rod holder. In one form, the spine rod has an essentially pentagonal cross-section that thus essentially defines angled sides or side surfaces that interact with the spinal rod holder opening to positively seat the spine rod into the spinal rod holder and prevent spine rod from rotation. In the pentagonal cross-section form, the spine rod has a top or posterior side/side surface, a bottom or anterior side/side surface, a first lateral side/side surface, a second lateral side/side surface, a first angled sub-lateral side/side surface and a second angled sub-lateral side/side surface. The first and second angled sub-lateral sides/side surfaces provide contact with angled sides of the spine rod holder opening. In another form, the spine rod has an essentially V-shaped cross-section that defines sides/side surfaces that interact with the spinal rod holder opening.Type: GrantFiled: September 10, 2009Date of Patent: March 17, 2015Assignee: Life Spine, Inc.Inventor: Michael S.
