Patent number: 8523906Abstract: Apparatus and devices for percutaneously extending an existing spinal construct ipsilaterally with an additional spinal construct in a patient are disclosed. The additional spinal construct comprises a rod connector that includes an elongate additional rod integrally attached thereto. The additional rod is placed through an access port in a first orientation generally parallel to the longitudinal axis of the access port and rotated to a different second orientation generally transverse to the longitudinal axis of the access port. During such rotation the additional rod is moved subcutaneously beneath the skin of the patient from the existing spinal rod to an additional bone engaging implant. In another arrangement, the extension of an existing spinal construct in a minimally invasive procedure comprises a rod connector having an offset support for receiving an additional spinal rod that may be placed laterally interiorly or exteriorly of the existing spinal construct.Type: GrantFiled: September 14, 2012Date of Patent: September 3, 2013Assignee: Spine Wave, Inc.Inventors: Scott McLean, Tim E.

Patent number: 8454664Abstract: A method of attaching a curved rod to a plurality of pedicle screws in the thoracic region of the spine is disclosed. Preferably, the method is practiced in a procedure for percutaneously fixing the rod to the pedicle screws through slots formed through a plurality of screw extensions releasably attached respectively to the pedicle screws. The method includes the steps of releasably and pivotally attaching the curved rod to a rod introducer having a handle and holding the rod initially in a fixed position. The rod is introduced in the fixed position through the slots in the extensions with the rod curvature defining a lordotic angle relative to the spine. The rod is released from the fixed position without separating the rod from the introducer. While the rod is in the released position the handle is rotated 180° thereby rotating the rod to a kyphotic angle relative to the thoracic region of the spine.Type: GrantFiled: June 8, 2011Date of Patent: June 4, 2013Assignee: Spine Wave, Inc.Inventor: Scott McLean

Patent number: 8450288Abstract: A method for the pre-treatment of an intervertebral disc prior to the introduction of a disc prosthesis or implant includes removing at least a portion of the nucleus pulposus of the intervertebral disc to expose at least a portion of the endplate of an adjacent vertebra to the disc. A fluent treatment material is then injected into the disc space to come into contact with the portion of the endplate. The fluent treatment material is operable to prepare the portion of the endplate to accommodate a disc prosthesis, implant or graft subsequently introduced into the disc space. Different fluent treatment materials are provided that depend upon the condition of the vertebral endplates.Type: GrantFiled: February 3, 2005Date of Patent: May 28, 2013Assignee: Spine Wave, Inc.Inventor: Lawrence M.

Publication number: 20130131811Abstract: An expandable interbody fusion device includes superior and inferior endplates that are configured to receive a sequentially inserted stack of interlocking expansion members or wafers. The like-configured wafers include features on their top and bottom surfaces that interlock the wafers in multiple degrees of freedom so that the wafer stack is not disrupted when the fusion device is fully expanded. One of the interlocking features includes a plurality of prongs projecting from an upper surface of the wafers and into a recess defined in the lower surface of an adjacent previously inserted like-configured wafer. The prongs and recesses are configured to prevent retrograde movement of each new wafer in a direction opposite the direction of insertion. Other interlocking features prevent movement in the direction of insertion, transverse to the insertion direction and vertically within the stack.Type: ApplicationFiled: January 8, 2013Publication date: May 23, 2013Applicant: SPINE WAVE, INC.Inventors: PETER BARREIRO, DENNIS TY, MICHAEL E.

Patent number: 8444694Abstract: A method for treating a diseased or damaged spinal disc comprises the steps of: (a) providing access to the nucleus pulposus through the annulus; (b) removing at least a portion of the nucleus pulposus to create an intradiscal space; (c) determining the size of the intradiscal space; and (d) sealably introducing under pressure a curable biomaterial through the annulus directly into the intradiscal space. The step of determining the size of the intradiscal space may be accomplished by expanding a compliant balloon within the intradiscal space using a contrast medium capable of visualization under fluoroscopy. The curable material is sealably introduced through a vented needle inserted through the opening. The curable biomaterial is introduced until a quantity of the material flows into the vent.Type: GrantFiled: August 23, 2010Date of Patent: May 21, 2013Assignee: Spine Wave, Inc.Inventors: Keith Collins, Thomas G.

Publication number: 20130123927Abstract: Described here are deformable, monolithic, stabilization devices, or implants, suitable for use within bone and between bones, for instance, to fuse vertebral bodies, to repair herniated discs, or to repair spinal compression fractures. The implants are introduced into a chosen site at a first, smaller height and then plastically deformed to achieve a second, but unique, pre-selected, larger height. Variations of the device provide one or more specific larger heights. The devices are particularly suitable as intervertebral spinal fusion implants for the immobilization of adjacent vertebral bodies. Methods of deploying the implants are also described as are instruments for such deployment. Also described are variations of the device particularly suitable as sizing instruments. These versions are elastic, i.e., not plastically deformable, and may be restored to their original size. Many of the described variations include deformable regions serving as hinges.Type: ApplicationFiled: June 27, 2011Publication date: May 16, 2013Applicant: SPINE WAVE, INC.Inventor: Hugues Malandain

Patent number: 8430885Abstract: ?n apparatus and method for distracting, in a given direction, and supporting two tissue surfaces is provided. A plurality of wafers are consecutively inserted using a wafer insertion apparatus between the two tissue surfaces to create a column of wafers. A detachable wafer assembly is provided that includes a base wafer initially associated with a track assembly of a wafer insertion apparatus. The base wafer is dislodged from the track assembly so that the base wafer is left within the distraction site as the track assembly is removed. A top cap wafer is provided that is situated at the top of the wafer stack, in which the top cap wafer is larger than the remaining wafers to form a gap surrounding the stack to receive biologic material.Type: GrantFiled: November 24, 2009Date of Patent: April 30, 2013Assignee: Spine Wave, Inc.Inventors: Richard J.
