Appl. No.:

13/358280

Inventors:

Walter Cuevas - Irvine CA, US
Robert Flower - Sun City CA, US
Fausto Olmos - Laguna Niguel CA, US

Peter Davis - Dana Point CA, US

Assignee:

INTERVENTIONAL SPINE, INC. - Irvine CA

International Classification:

A61F 2/44

US Classification:

623 1716

Abstract:

An intervertebral implant and related methods of use are provided for treatment of spaces between two vertebrae. The implant can comprise a first member and a second member that are configured for engagement in a stacked configuration. The first member and second member can be inserted separately so that the intervertebral space can be reached through limited access pathways. The first member and second member can be coupled in situ in the intervertebral space to form an implant of desired height. In this manner, an intervertebral implant having final dimensions that would not fit through a limited access pathway can be implanted through the access pathway by inserting the implant in separate member pieces.

International Classification:

A61B 17/02
A61B 1/04
A61B 1/00

Abstract:

A camera system for use with retractors. The system includes a camera assembly configured for mounting on the proximal end of a retractor system, such as the proximal end of a blade such that the entirety of the camera assembly is disposed at the proximal end of the retractor system may be disposed such that the distal-most optical element overhangs the working channel established by the retractor, and includes a reflector and a rotatable mount for the reflector, camera assembly viewing axis may be altered without changing the position of the entire camera assembly.
