Abstract

A portal system for intervertebral surgical fusion procedures includes a longitudinally elongated hollow tubular body comprising a first wall, a second wall opposing the first and a third wall spanning from a first edge of the first wall to a first edge of the second wall. A channel is defined longitudinally through at least one of the first, second and third end walls. The fourth wall of the body is at least partially open or can be completely enclosed.

First claim

What is claimed is:

1. A portal system for intervertebral surgical fusion procedures, comprising:
a longitudinally elongated hollow body comprising a first wall, a second wall opposing the first, a third wall spanning from a first edge of the first wall to a first edge of the second wall and a fourth longitudinal side being located opposite the third wall and spanning between the second edge of the first wall and the second edge of the second wall; and
a channel defined longitudinally through at least one of the first, second and third walls,
wherein the fourth side defines an opening that extends from a proximal end of the longitudinally elongated hollow body towards a distal end of the longitudinally elongated hollow body for at least a majority of a longitudinal length of the longitudinally elongated hollow body, and
wherein the fourth side further comprises a solid fourth wall portion located adjacent to the distal end, opposite the third wall, and spanning between a second edge of the first wall and a second edge of the second wall.

2. The portal system of claim 1 , wherein the channel is a rectangular slot when viewed in a lateral cross-section.

3. The portal system of claim 2 , wherein the channel includes an opening to the hollow interior of the body.

4. The portal system of claim 1 , wherein the channel is a circular bore when viewed in a lateral cross-section.

5. The portal system of claim 1 , wherein the body, when viewed in a lateral cross-section, is a rectangle with rounded corners.

6. The portal system of claim 1 , further including a clamp securable to the body.

7. The portal system of claim 1 , wherein the distal end of the body defines an opening that is larger than an opening defined in the proximal end of the body.
