Title:
INTERBODY IMPLANT WITH CONCAVE PROFILED NOSE
Document Type and Number:
WIPO Patent Application WO/2018/112324
Kind Code:
A3
Abstract:
An interbody implant and inserter tool for spinal fusion. The interbody implant includes a cage portion and a nose portion. In some embodiments, an outer surface of the nose portion defines at least a first concave profile in a first direction, and may define a second concave profile in a second direction, the second direction being perpendicular to the first direction. The outer surface may also define an oblong cross-section normal to a nose axis. The oblong cross-section may be axisymmetric or continuously curved (or both) about the nose axis. The concave profile(s) enable easier initial insertion of for more precisely locating the interbody implant, so that the greater insertion forces required during implantation do not occur until the interbody implant is securely and accurately placed.
