Spinal implant having compliant surface

Abstract

The invention involves an interbody implant (spacer) and a method of manufacturing an interbody implant for use in spinal procedures, having one or more compliant surfaces to more evenly distribute the load applied to the bone while in use, as well as aid in bone growth and attachment. The interbody spacer has one or more unique surfaces designed to comply (flex) upon receiving a predetermined load. By flexing, the surface contact area between the implant and the bone is increased to distribute the load over a larger area. In order to provide the flexing, at least a portion of the implant is constructed from a plurality of bar springs that are interconnected or integrally connected with each other to conform to a surface while providing sufficient support for use as an implant.
