Figure 4
The schematic has three views of a wavy cylindrical implant between rectangular end plates. The left view presents an end plate with a central circular feature and dimension labels A, B, b, and a. The middle view presents the implant from the side, with a wave path around a straight central body and end plates with circular holes. The pitch is labelled P, and the cylinder diameter is labelled D. The top-right view presents the same implant in a three-dimensional view.Spring model with elliptical core modelled using the SolidWorks software package from Dassault Systèmes
