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. Wilson, Jared Walkenhorst, Dennis Lee, Andrew Carter, John Pafford, Mark D. LoGuidice, Lance Middleton, Lawrence Boyd

Patent number: 7740660Abstract: A method for treating a herniated spinal disc between opposing vertebral bodies having a damaged outer annulus and an inner nucleus pulposus comprises the steps of: providing access to the nucleus pulposus through the annulus; removing at least a portion of the nucleus pulposus to create an intradiscal space; applying a first distraction force on the opposing vertebral bodies from within the intradiscal space; applying a second distraction force on the opposing vertebral bodies externally of the intradiscal space; and introducing a curable biomaterial through the annulus access directly into the intradiscal space. The first distraction force is applied within the disc space to distract the anterior aspect of the intradiscal space, while the second distraction force is applied exterior to the disc to act on the posterior aspect of the vertebral bodies. The first distraction force is applied prior to the application of the second distraction force and then removed.Type: GrantFiled: June 29, 2005Date of Patent: June 22, 2010Assignee: Spine Wave, Inc.Inventors: Keith Collins, Thomas G.

Patent number: 7722579Abstract: A vented needle assembly is provided for sealably injecting biomaterial into an intradiscal space interiorly of the annulus of a spinal disc and for providing an exhaust for the intradiscal space. The vented needle assembly comprises a compressible seal body for pressing against an outer surface of the annulus, and a needle extending through the seal. The needle may be configured to connect to a syringe for pressure injection of the biomaterial. The seal includes a vent extending therethrough with an opening for communication with the intradiscal space and an opening for the discharge of excess biomaterial filling the intradiscal space. A kit of parts is also provided for use in the treatment of a spinal disc, the kit comprising the vented needle assembly and an inflatable trial device. The trial device is removably introduced into the intradiscal space and inflated to determine the available size of the intradiscal space.Type: GrantFiled: June 29, 2005Date of Patent: May 25, 2010Assignee: Spine Wave, Inc.Inventors: Keith Collins, Lawrence Boyd, Andrew Carter, Dennis Lee, John Pafford, Jared Walkenhorst, Thomas G.

Patent number: 7575577Abstract: A system and method is provided for maintaining a proper intervertebral disc height during the replacement or augmentation of the spinal disc. In one embodiment, a cannulated distractor is used to distract the adjacent vertebrae and maintain a proper disc space height. The cannulated distractor is fluidly connected to a source of fluent material for injection into the disc space. The distraction includes a distraction tip resident within the disc space that includes a central lumen and a number of openings communicating with the lumen to dispense the fluent material within the disc space.Type: GrantFiled: September 22, 2003Date of Patent: August 18, 2009Assignee: SpineWaveInventors: Lawrence Boyd, Upton L.

Patent number: 7556650Abstract: A method for treating a diseased or damaged spinal disc having an inner nucleus pulposus and an outer annulus is provided comprises the steps of: providing access to the nucleus pulposus through the annulus; removing at least a portion of the nucleus pulposus to create an intradiscal space; determining the integrity of the annulus; and then sealably introducing under pressure a curable biomaterial through the annulus access directly into the intradiscal space. The step of determining the integrity of the annulus may be accomplished by introducing into the disc a fluid solution under a first pressure. The curable biomaterial may subsequently be introduced through the annulus directly into said intradiscal space at a second pressure that is increased or decreased from the first pressure as a function of the viscosity of the biomaterial relative to the fluid solution. In certain embodiments, a distraction force is applied to the disc space.Type: GrantFiled: June 29, 2005Date of Patent: July 7, 2009Assignee: Spine Wave, Inc.Inventors: Keith Collins, Thomas G.

Publication number: 20070016295Abstract: This invention relates to arthodesis for stabilizing the spine. More specifically, the present invention is directed to an intervertebral spacer formed of a bone material and to methods of treating patients having spinal deformities. The invention provides a spinal implant assembly comprising bone-derived components. The bone-derived components can be formed into modular units that can be assembled to provide a wide variety of implant configurations. In addition, the bone-derived components can form scaffold that can withstand the shear and impact forces necessary to insert the assembled implant into a disc space between adjacent vertebrae. In preferred forms the implants define an open spacer that serves as a depot for receipt of an osteoconductive material. The ostoegenic material is preferably a moldable filler that can form a molded reinforced implant.Type: ApplicationFiled: June 10, 2004Publication date: January 18, 2007Inventor: Lawrence Boyd

Publication number: 20060179418Abstract: Exemplary embodiments of the present invention comprise a tool kit for the design and execution of research protocols, for example, comprising a web-based research protocol composer for generating a data processing protocol; a collector for collecting data entered via an internet based questionnaire; a database for data; and a protocol processing routine for processing data and generating an output. For example, the toolkit suitably serves as a “hub” of a global research environment (e.g., connected via the Internet or other network) that creates and connects communities of researchers and facilitates the sharing of software and results. Additionally, the present invention provides standardized and custom online “programs” or “scripts” (referred to herein as “protocols”) that define and guide events in experiments, clinical trials, surveys, and other kinds of studies. These protocols are created and executed online.Type: ApplicationFiled: February 8, 2006Publication date: August 10, 2006Applicant: PASADERO, INC.Inventor: Lawrence Boyd
