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.

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.

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.

Patent number: 8343162Abstract: An intervertebral distraction tool has a clamshell head with upper and lower halves, each having a curvate outer surface and a flat inner surface. The distal side of the head is hinged so that the head opens and closes from the proximal side of the head. The hinge is a separating hinge that allows the halves to not only angulate with respect to one another about the hinge axis, but also to vertically separate from one another at the hinge. A distraction separator has decreasing taper at its distal end and a longitudinal bore that accommodates the elongate shaft of the trial so that the separator can be moved longitudinally relative to the shaft. Upon forward movement of the separator, the tapered upper and lower surfaces engage the flat inner surfaces of the head, causing the halves to angulate about the hinge axis of the head, thereby opening the head.Type: GrantFiled: November 5, 2007Date of Patent: January 1, 2013Assignee: SpineCore, Inc.Inventors: James D. Ralph, Thomas N. Troxell

Publication number: 20120283739Abstract: A driver assembly for affixing a surgical fastener to a target location is provided. Operation of the driver assembly inserts the surgical fastener in two stages, first an alignment stage through application of a distally directed force to partially insert the surgical fastener, and then a fastening stage to fully insert and seat the surgical fastener to a proper depth or compression level. The driver assembly comprises a spring loaded automatic trigger mechanism that may be adapted for use with a linearly insertable or a rotationally insertable surgical fastener. Application of the distally directed force actuates the trigger mechanism, wherein a corresponding impact force is delivered for seating the surgical fastener, coupled to a distal end of the driver assembly, upon alignment of cam and receiver elements embodied within the trigger mechanism.Type: ApplicationFiled: May 3, 2012Publication date: November 8, 2012Inventors: James D.
