System and method for minimally invasive spinal surgery
First Claim
1. A system for installing a cross member between first and second anchor members within a patient'"'"'s body using a wire member, the system comprising:
- first and second docking members configured to be removably coupled to the first and second anchor members substantially along respective first and second axes, each docking member having a first end with an opening, a second end, a body extending between the first and second ends, the body having an outer surface with an opening, and a bore extending from the opening on the first end to the opening on the outer surface; and
a wire member, the wire member configured to extend into the opening in the first end of the first docking member, through the bore in the first docking member, out the opening in the outer surface of the first docking member, into the opening in the outer surface of the second docking member, through the bore of the second docking member, and out the opening in the first end of the second docking member;
wherein the opening on the outer surface of the first docking member is configured to be aligned with the opening on the outer surface of the second docking member, the bore in the first docking member being configured to direct the wire member from the opening on the first end, through the body, and out the opening on the outer surface of the first docking member toward the opening on the outer surface of the second docking member, the first docking member and wire member configured for controlled direction of the wire member from the opening of the outer surface of the first docking member.

Abstract
A system for installing a cross member between first and second anchor members within a patient'"'"'s body generally includes first and second docking members configured to be removably coupled to the respective first and second anchor members. Each docking member has a first end with an opening, a second end, and a body extending between the first and second ends. The body includes an outer surface with an opening, and a bore extends from the opening on the first end of the body to the opening on the outer surface. The openings on the outer surface of each docking member are configured to be aligned so that the bore in the first docking member is able to direct a wire member into the bore in the second docking member. A method for minimally invasive surgery using the system is also disclosed.

8. A minimally invasive spinal surgery system for positioning components within in a patient'"'"'s body, the system comprising:
-
first and second anchor members; first and second docking members configured to be removably coupled to the respective first and second anchor members, each docking member having a first end with an opening, a second end, a body extending between the first and second ends, the body having an outer surface with an opening, and a bore extending from the opening on the first end to the opening on the outer surface, wherein the opening on the outer surface of the first docking member is configured to be aligned with the opening on the outer surface of the second docking member; a wire member configured to be inserted through the bore in the first docking member and received in the bore of the second docking member, the first and second docking members being removable from the wire member after the wire member is positioned within the patient'"'"'s body; and a cross member having a central bore configured to be guided over the wire member after the first and second docking members are removed, the cross member further configured to be secured to both the first and second anchor members. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A method for minimally invasive surgery, comprising the steps of:
-
creating a first and second access channels extending to respective first and second locations within a patient'"'"'s body; inserting first and second anchor members in the patient'"'"'s body through the respective first and second access channels; inserting first and second docking members into the patient'"'"'s body through the respective first and second access channels, each docking member having a first end with an opening, a second end, a body extending between the first and second ends, the body having an outer surface with an opening, and a bore extending from the opening on the first end to the opening on the outer surface; aligning the opening on the outer surface of the first docking member with the opening on the outer surface of the second docking member; and inserting a wire member into the opening in the first end of the first docking member, through the bore in the first docking member, out the opening in the outer surface of the first docking member, into the opening in the outer surface of the second docking member, through the bore of the second docking member, and out the opening in the first end of the second docking member. - View Dependent Claims (19, 20, 21)
