US Patent:

6478798, Nov 12, 2002

Filed:

May 17, 2001

Appl. No.:

09/861278

Inventors:

Robert S. Howland - Seal Beach CA 90740

International Classification:

A61B 1756

US Classification:

606 61

Abstract:

An anchor screw assembly includes a screw having a threaded portion and a head portion to which a swing bolt is pivotally coupled. A clamp assembly includes lower and upper clamp portions that are securable on the swing bolt by a fastener. The clamp portions include noncircular first passages for receiving a noncircular region of the swing bolt therethrough to prevent rotation of the clamp assembly on the swing bolt, and cooperating grooves that together define a second passage. The head portion of the screw includes a shoulder, and the lower clamp portion frictionally engages the shoulder when the clamp assembly is fully secured on the swing bolt, thereby securing the swing bolt relative to the screw. Multiple screw assemblies are screwed into adjacent vertebrae, and a rod is secured within the second passages between the anchor screw assemblies to stabilize the vertebrae.

International Classification:

A61B 1756

US Classification:

606 61, 606 73

Abstract:

A spinal fixation system includes a plurality of anchor screw assemblies, e. g. including anchor screws and clamp assemblies defining rod passages therethrough. A rod is receivable in the rod passages between the anchor screw assemblies, and a spacer is securable on the rod. During use, a first anchor screw is screwed into a first vertebra, and a second anchor screw is screwed into a second vertebra adjacent the first vertebra, and clamp assemblies are mounted to each anchor screw. A rod is secured between the anchor screw assemblies, thereby fixing a relative spacing of the first and second vertebrae. A spacer is crimped onto the exposed portion of the rod between the anchor screw assemblies, the spacer extending between the anchor screw assemblies to prevent the anchor screw assemblies, and, consequently, the first and second vertebrae, from moving towards one another.

Inventors:

Robert Howland - Seal Beach CA, US

International Classification:

A61B017/58

US Classification:

606/061000

Abstract:

An anchor screw assembly includes a screw having a threaded portion and a head portion to which a swing bolt is pivotally coupled. A clamp assembly includes lower and upper clamp portions assembled into connecting beams that are securable on the swing bolt by a fastener. The clamp portions include first passages for receiving an intermediate region of the swing bolt therethrough to receivably retain the clamp assembly on the connecting beam and on the swing bolt. The head portion of the screw includes a shoulder, and the lower clamp portion has a seat that frictionally engages the shoulder when the clamp assembly is fully secured on the connecting beam and swing bolt, thereby securing the swing bolt relative to the screw. Multiple screw assemblies are screwed into adjacent vertebrae, and a connecting member is secured by the clamp assemblies between the anchor screw assemblies to stabilize the vertebrae.

Appl. No.:

11/216876

Inventors:

Robert Howland - Seal Beach CA, US

International Classification:

A61F 2/30

US Classification:

606061000

Abstract:

A spinal fixation system includes a plurality of anchor screw assemblies, e.g. including anchor screws and clamp assemblies defining rod passages therethrough. A rod is receivable in the rod passages between the anchor screw assemblies, and a spacer is securable on the rod. The rod is preferably serrated over less than about 25% of the peripheral surface thereof, and the clamp assemblies preferably include engagement surfaces that include similarly spaced and oriented serrations. During use, a first anchor screw is screwed into a first vertebra, and a second anchor screw is screwed into a second vertebra adjacent the first vertebra, and clamp assemblies are mounted to each anchor screw. A rod is secured between the anchor screw assemblies, thereby fixing a relative spacing of the first and second vertebrae. A spacer may be crimped onto the exposed portion of the rod between the anchor screw assemblies, the spacer extending between the anchor screw assemblies to prevent the anchor screw assemblies, and, consequently, the first and second vertebrae, from moving towards one another.

Assignee:

Advanced Spine Fixation Systems, Inc. - Cypress CA

International Classification:

A61B 1770

US Classification:

606 61

Abstract:

A connector for cross bracing a first spine rod and a second spine rod. The connector comprises a cross brace, upper saddles and connectors for connecting the upper saddles and cross brace to the first and second spine rods to thereby cross brace the first and second spine rods. Lower saddles are integrally formed at opposite ends of the cross brace to mate with the upper saddles in gripping the spine rods.

Assignee:

Advanced Spine Fixation Systems, Incorporated - Irvine CA

International Classification:

A61B 1770

US Classification:

606 61

Abstract:

A spinal fixation system utilizing grapple hooks comprising a lower hook attached to the lamina on the caudal-side of a vertebra and an upper hook attached to the lamina on the cranial-side of a vertebra. The hooks clamp the vertebra lamina in the center. Thus, the hooks clamp the lamina at the spinous process which is the strongest part of the lamina. Bolts are provided for attaching the lower hook to the upper hook to thereby attach the lower and upper hooks to the vertebra and clamps for attaching the lower and upper hooks to spine rods. A spinal fixation kit is provided with a plurality of uniquely configured fixation systems to assure satisfactory fit to any vertebra of any patient, and specially designed tools are preferably provided to aide in a method of implanting the systems thereby reducing the time required for implantation.
