Interbody implant with independent control of expansion at multiple locations
First Claim
1. A spinal implant for placement between first and second vertebral bodies, comprising:
- a body having a first surface for engaging a first vertebral body;
a first movable member having a first end movable away from the body at a first location;
a second movable member having a second end movable away from the body at a second location;
at least one extendable support element connected to the body, the first extendable support element being actuatable to expand so as to induce movement of at least one of the first and second ends of the respective first and second movable members away from the body;
a first locking element at the first location; and
a second locking element at the second location;
wherein the first locking element is manipulatable by a user to move between an unlocked configuration and a locked configuration, independent of a position of the first movable member away from the body, such that, when in the locked configuration, the first locking element restrains movement of the first movable member away from the body without restraining movement of the second movable member away from the body; and
wherein the second locking element is manipulatable by a user to move between an unlocked configuration and a locked configuration, independent of a position of the second movable member away from the body, such that, when in the locked configuration, the second locking element restrains movement of the second movable member away from the body without restraining movement of the first movable member away from the body.

Abstract
Expandable spinal interbody implants include a body and at least one extendable support element connected thereto. Such an implant may include a second extendable support element and a tool selectively positionable with respect to the implant so as to independently or simultaneously expand both extendable support elements. In another example, such an implant may include, at each of a first and second location, a respective movable member and a respective locking element. The at least one extendable support element may be actuatable to expand so as to induce movement of at least one of the movable members away from the body. The locking elements at each of the first and second locations may be selectively lockable such that, when locked, the locking element restrains movement of the associated movable member at that location away from the body without restraining movement of the other movable member away from the body.
