<p>A spark erosion electrode (1) can create a contoured surface to facilitate the growth and adhesion of bone tissue on the surface. The electrode (1) includes a collection of parallel electrode members (10), which are preferably tubular. These members (10) are held by a releasable clamp (2) such that they can be moved axially whereby ends of the members (10) can form a negative pattern of a required contour which can then be replicated on the surface of an object such as that of a bone implant.</p> |
