Filed:

Jun 3, 2022

Appl. No.:

17/832545

Inventors:

- Irving TX, US
Thomas Purcell - Irving TX, US

Assignee:

Astura Medical Inc. - Irving TX

International Classification:

A61F 2/46
A61F 2/44

Abstract:

An expandable interbody spacer that is delivered in the anterior approach with adjustable height and end plate angulation (lordosis). The expandable interbody spacer is configured to have an initial collapsed state having a first height suitable for being inserted into an intervertebral space defined by a pair of adjacent vertebrae, and an expanded state having a second height that is greater than the first height. The expandable interbody spacer may be expanded from the initial collapsed state to the expanded state in-situ. The expanded state increases the distance between the adjacent vertebrae and provides support to the adjacent vertebrae while bone fusion occurs and also provides rigid support between the adjacent vertebrae that withstands compressive forces. By inserting the expandable interbody spacer into the intervertebral space in the initial collapsed state, it is possible to perform the surgery percutaneously with minimal disruption to tissues surrounding the surgical site and intervening soft tissue structures.
