Filed:

Jul 14, 2006

Appl. No.:

11/487102

Inventors:

Roy J. Couvillion - Lafayette LA, US
John E. Cobb - Lafayette LA, US

International Classification:

A61B 17/32

US Classification:

83 39, 83454, 83459, 83762, 606 87, 269 872

Abstract:

A base having a substantially planar surface, an upright support member and a blade guide having a serrated surface that can be adjustably positioned along the planar surface. The blade guide is biased toward an opposing serrated plate member to securely hold a section of donor bone, and locked in place using an adjustable lever-cam linkage.

Inventors:

Roy J. Couvillion - Lafayette LA, US
John E. Cobb - Lafayette LA, US

International Classification:

A61B 17/32

US Classification:

83 34, 83456, 83763

Abstract:

A base having a substantially planar surface, a plurality of upright fingers, and a blade guide that can be adjustably positioned along the planar surface. The blade guide can be biased toward the upright fingers to secure a section of donor bone between the blade guide and the upright fingers. Aligned openings in the blade guide and planar surface, as well as the gaps between the upright fingers, permit precision cutting of a donor bone section to prepare a graft having a desired size and/or configuration.

Appl. No.:

12/896292

Inventors:

John Cobb - Lafayette LA, US
William Atkinson - Lafayette LA, US
Peter Harris - Boca Raton FL, US

International Classification:

A61F 2/44

US Classification:

623 1716

Abstract:

An intervertebral implant device, including: a pair of substantially parallel opposed arcuate surfaces; a pair of substantially parallel opposed frictional surfaces each including a plurality of raised structures; a substantially curved end wall joining the pair of parallel opposed arcuate surfaces; and a substantially recessed end wall joining the pair of parallel opposed arcuate surfaces; wherein the intervertebral implant device defines one or more voids in which a bone graft material is selectively disposed. Preferably, the substantially recessed end wall is configured to selectively and pivotably receive one or more surgical implantation devices.

Appl. No.:

13/294333

Inventors:

John Cobb - Lafayette LA, US
William Atkinson - Lafayette LA, US

International Classification:

A61B 17/32

US Classification:

606170

Abstract:

A single-use, multi-purpose neuro-dissector (“dissector”), suitable for a variety of surgical procedures, is disclosed. A handle of a material which degrades in heat sufficient to sterilize same holds an extended, slender rod, preferably of stainless steel or similar suitable material. A section of the rod near its distal end (away from the handle) is turned at an angle to the remainder of the rod, and a cutting surface and cutting edge are formed in the turned-down section. The distal end of the rod forms a non-cutting tip, for example a blunt ball tip, to avoid unintentional cutting of surrounding tissues. The cutting surface and edge are coated with a material which prevents re-sharpening, such as titanium nitride. The combination of a handle material which degrades in the heat of sterilization, if attempted, and a cutting surface which is not re-sharpenable, render the dissector a single-use device.

US Classification:

Abstract:

Embodiments of apparatus, systems, and methods relating to spinal implants. In some embodiments, the spinal implant may comprise a first sidewall, a second sidewall opposite from the first sidewall, a pair of opposed frictional surfaces each comprising a plurality of raised structures, a first end wall joining the pair of opposed sidewall surfaces, and a second end wall joining the first sidewall and the second sidewall. The second end wall may comprise a recess formed by a first wall portion and a second wall portion arranged at an angle to one another to form a fish-tailed structure configured to be engaged with an inserter instrument. The interface between the recess and the inserter instrument may be configured to at least substantially eliminate any point or line contacts between the inserter instrument and the spinal implant during a flip maneuver of the spinal implant within an intervertebral space of a patient.
