Filed:

Feb 11, 2008

Appl. No.:

12/069721

Inventors:

Javier Garcia-Bengochea - Jacksonville FL, US
Jeffrey Allen Guyer - Cardiff By the Sea CA, US
Thomas Purcell - Del Mar CA, US

Assignee:

Alphatec Spine, Inc. - Carlsbad CA

International Classification:

A61B 17/02
A61B 17/34

US Classification:

600114, 606 86 A

Abstract:

A curvilinear spinal access device for performing a procedure on a spine of a patient is disclosed. The device includes a working portal configured to be advanced toward a surgical site located at the spine of the patient. The working portal includes a distal end and a proximate end, a working portal housing having an open interior channel disposed between the distal end and the proximate end, an exterior channel disposed on an outside surface of the working portal housing and between the distal end and the proximate end. The distal end is configured to be disposed at the surgical site and the proximate end is disposed away from the surgical site. The housing has a curved shape defined between the proximate end and the distal end, wherein the proximate end is disposed with respect to the distal end. The working channel is configured to allow advancement of at least one surgical tool and/or at least one implant toward the surgical site.

International Classification:

A61B 17/00

US Classification:

606108

Abstract:

A system for performing a procedure on a spine of a patient includes a curved tissue distractor, a curved housing, and an exterior channel. The curved tissue distractor includes a first distractor ramp and a second distractor ramp. The curved housing is configured to slide between the first and second distractor ramps. The curved housing includes a distal end, a proximal end, and an interior channel disposed between the distal end and the proximate end. The exterior channel is disposed on an outside surface of the curved housing and between the distal end and the proximal end. The curved housing is configured to slide between the first and second distractor ramps to provide access through the interior channel to the spine.
