Patent number: 8915921Abstract: An apparatus and method for collecting particulate bone from the operating site during an osteotomy or bone drilling procedure so that it can be used subsequently to augment the bone fusion process. A bone cutting or drilling tool is provided with a module for collecting particulate bone simultaneously with cutting or drilling the bone. The collected particulate bone is transferred continuously to a sterile containment module and maintained under sterile conditions until it is prepared for re-use in the patient.Type: GrantFiled: June 25, 2010Date of Patent: December 23, 2014Assignee: BioDynamics LLCInventors: James D.

Patent number: 8870958Abstract: An intervertebral spacer has curvate upper and lower rough surfaces that stimulate bone growth and is formed from a porous material that facilitates bone growth thereinto. The spacer has a plurality of smooth linear grooves to facilitate insertion of the spacer into an intervertebral space using a spacer insertion tool that has a scissor-style body. Each of the insertion tool's arm's heads has an inner surface having a pair of smoothed linear protrusions that fit within the linear grooves of the spacer when the heads are closed about the spacer. When the spacer is held, spaces are present between the spacer's rough surfaces and the heads' inner surfaces so that when the protrusions are longitudinally slid from the grooves to leave the spacer in the intervertebral spacer, the rough surfaces are not disturbed.Type: GrantFiled: April 21, 2011Date of Patent: October 28, 2014Assignee: SpineCore, Inc.Inventors: James D. Ralph, Thomas N. Troxell

Patent number: 8790377Abstract: A bone plate and system is provided. The bone fixation plate conforms to the contour of an irregularly shaped bone and eliminates the need for pre-bending or intraoperative bending of the plate. The bone plate is applied to the bone in a generally flat condition and the process of installing and tightening the bone screws in the prescribed order serves to contour the plate to the underlying bone while providing sufficient strength to effect bone healing. The geometry of the plate allows the plate to follow the contour of an irregularly shaped bone, preventing prominence and patient palpability and streamlining the surgical procedure.Type: GrantFiled: February 21, 2013Date of Patent: July 29, 2014Assignee: MBD Medical LLCInventors: James D. Ralph, Thomas N. Troxell, Mark Michels, Thomas D. Meade

Publication number: 20140172109Abstract: An orthopedic device set, including: a plurality of intervertebral spacer elements, each spacer element having a different axial thickness from each other element, the axial thicknesses being selected to increase by an increment from one element to another; and an instrument for holding ones of the intervertebral spacer elements, the instrument comprising a shaft having a distal end, a selectively grasping subassembly for alternatively rigidly holding each spacer element at the distal end so that the spacer element cannot move relative to the instrument, and releasing the spacer element.Type: ApplicationFiled: February 19, 2014Publication date: June 19, 2014Applicant: SPINECORE, INC.Inventors: James D. Ralph, Stephen Tatar, Thomas J. Errico

Publication number: 20140142704Abstract: An instrument for holding an intervertebral spacer is provided. The instrument includes a compression assembly and a fixed shaft forming a handle and a compression surface. The compression assembly includes a selectively engageable shaft axially movable relative to a longitudinal axis of the fixed shaft. The engageable shaft forms a hook having a surface complimentary to the compression surface to define an enclosure for engagement with an annular groove of the spacer. The compression assembly includes a compression trigger mechanically connected to the engageable shaft for axially moving the hook from a first position relative to the fixed shaft in which the enclosure engages the spacer such that the spacer is held by the enclosure to a second position relative to the fixed shaft in which the spacer is disengaged from at least one of the hook surface and the compression surface such that the enclosure disengages the spacer.Type: ApplicationFiled: November 21, 2013Publication date: May 22, 2014Applicant: SpineCore, Inc.Inventors: James D. Ralph, Stephen Tatar, Thomas J. Errico

Patent number: 8608752Abstract: An insertion tool for inserting an intervertebral spacer is provided. The tool includes first and second pincers. The first pincer is fixed and the second pincer is pivotably coupled to the first pincer at a pivot location in open-biased opposition to the first pincer. The tool includes a compression slide which may be selectively translated into and out of engagement with the second pincer. When the compression slide is in a predetermined engagement position with the second pincer, the first and second pincers are in a closed position for holding the intervertebral spacer. When the compression slide is out of engagement with the second pincer, the first and second pincers are in an open position for releasing the intervertebral spacer.Type: GrantFiled: June 27, 2012Date of Patent: December 17, 2013Assignee: SpineCore, Inc.Inventors: James D.

Patent number: 8597335Abstract: Strip fasteners and cranial plugs for use in reattaching a skull flap removed during brain surgery and methods of using the same. The strip fasteners are flexible and can be shaped to follow the perimeter contour of the skull flap. The cranial plugs can be used to reattach the skull flap or they can be installed after the skull flap is reattached using the strip fasteners. In some embodiments, the cranial plug(s) and strip fasteners can be installed at the same time. The strip fasteners and cranial plugs are designed to encourage bone growth and healing of the skull flap and they can be used to deliver medication and bone growth enhancement compositions to the surgical site.Type: GrantFiled: November 29, 2011Date of Patent: December 3, 2013Assignee: BioDynamics LLCInventors: James D.
