Filed:

Jan 14, 2002

Appl. No.:

10/043266

Inventors:

Glenn Robin Buttermann - Mahtomedi MN
Doug Wayne Cooper - Redwing MN

Assignee:

Dynamic Spine, Inc. - Solana Beach CA

International Classification:

A61B 1732

US Classification:

606 79

Abstract:

A cutting guide for use in spinal surgery includes a sidewall defining an internal cavity. A chisel guide, for use with the cutting guide, includes a first block member to be inserted into the internal cavity of the cutting guide to position the first block member adjacent the vertebral body. The chisel guide also includes a second block member connected to the first block member. An apparatus for creating a cavity in a vertebral body endplate and in an intervertebral disc may be a compressor or a distractor having at least one cutting implement thereon. A tensioner determines a proper elongation distance in a prosthesis implanted in a vertebral body.

US Classification:

623017130, 623017160, 623023470, 606096000

Abstract:

An embodiment of an intervertebral prosthetic device for implantation in a spine includes a rigid fixation member and a compressible member. The fixation member is configured to be placed in a cavity of a first vertebral body and against bone of the first vertebral body. The compressible member is configured to be placed in a cavity in an intervertebral disc and to be secured to the first fixation member. Another embodiment includes two compressible members and one fixation member. In this embodiment, the first and second compressible members are sized to substantially replace the nucleus pulposus of first and a second intervertebral discs, respectively, on either side of a vertebral body. The fixation member is sized to fit within a cavity in the vertebral body between the first and second compressible members.

Appl. No.:

12/149403

Inventors:

Glenn R. Buttermann - Mahtomedi MN, US

International Classification:

A61B 17/70
A61B 17/04

US Classification:

606249, 606246, 606300

Abstract:

An orthopaedic device to realign bone segments comprises first and second attachment members and a spacer member. The first attachment member is attached to a first rib bone or first transverse process of a vertebra. The second attachment member is attached to a second rib bone or second transverse process of a vertebra adjacent to the first rib bone or the first transverse process. The spacer member is positioned between the first and second attachment members. The spacer member provides distraction between the first and second rib bones or transverse processes to realign the rib bones. The spacer member is releasably connected to the first and second attachment members. The attachment members comprise a clamp and screw combination.

International Classification:

A61B 17/86
A61B 17/84

US Classification:

606305, 606324

Abstract:

An orthopaedic device to realign bone segments comprises first and second attachment members and a strut or spacer member. The first attachment member is attached to a first rib bone or first transverse process or first lamina of a vertebra. The second attachment member is attached to a second rib bone or second transverse process or second lamina of a vertebra. The strut is positioned between the first and second attachment members. The strut is fixedly or releasably connected to the first and second attachment members to couple the first attachment member to the second attachment member. The strut provides distraction between the first and second rib bones or transverse processes to realign the rib bones. The attachment members comprise a clamp and screw combination.
