US Classification:

623 1711, 623 1713

Abstract:

An method and apparatus is provided for achieving stability of an implant in an intervertebral space of the human body, including an implant having a superior surface and an inferior surface, the surfaces having no significant protrusions extending therefrom and at least one modular projection mateable with one of each superior and inferior surface of the implant to achieve stability within the intervertebral space. The implants can be selected form a group of artificial discs and spinal fusion cages.

Appl. No.:

11/432908

Inventors:

Andrew P. Dooris - Raynham MA, US
Christopher J. Rogers - Plymouth MA, US
Matthew L. Parsons - Dartmouth MA, US

Assignee:

DePuy Spine, Inc. - Raynham MA

International Classification:

A61F 2/44

US Classification:

623 1714, 623 1715

Abstract:

An intervertebral disc prosthesis comprises a superior endplate, an inferior endplate, and an intermediate core positioned between the endplates. The core comprises a central disc portion and a radial flange. The central disc portion of the core is defined by a superior bearing surface and inferior bearing surface. The radial flange of the core includes a first portion that extends radially outward from the central disc portion of the core. The radial flange also includes a second portion that extends axially from the first portion of the flange. The second portion of the flange extends a substantially greater distance toward the inferior endplate than toward the superior endplate. In one embodiment, the second portion of the flange extends completely to the inferior endplate and engages the inferior endplate when the inferior endplate is in a neutral position relative to the core.

US Classification:

623 1714, 623 1715, 606 99, 606 86 A

Abstract:

An intervertebral disc prosthesis comprises a first prosthesis component, a second prosthesis component, and an intermediate prosthesis component positioned between the first prosthesis component and the second prosthesis component. The first prosthesis component and second prosthesis component are configured to rotate upon the intermediate prosthesis component. The first prosthesis component includes a vertebra facing surface with a central channel formed in the vertebra facing surface. The central channel is designed and dimensioned to engage an insertion arm of a disc insertion tool. The first prosthesis component also includes at least one indentation configured to engage at least one retention arm of the disc insertion tool. The at least one indentation of the first prosthesis component may comprises at least one groove formed in a collar of the first prosthesis component. In one embodiment, the first and second prosthesis components are plates and the intermediate prosthesis component is a core.

International Classification:

A61F005/04

US Classification:

606053000

Abstract:

An attachment mechanism for a surgical instrument is provided which includes a receiving component having a longitudinal axis, a modular tip configured to be coupled in a rigid manner to the receiving component in two or less orientations, and a locking mechanism for securing the tip to the receiving component. A method for attaching a modular tip to a surgical instrument is also provided that includes actuating a locking mechanism, inserting a mating component of a modular tip into a receiving component by moving the mating component in a direction substantially perpendicular to a longitudinal axis of the receiving component, or by rotating the mating component relative to the receiving component, or a combination thereof, and releasing the locking mechanism to secure the tip to the receiving component.
