Abstract
An extracorporeally length-adjustable implant system comprises an implant component to be fastened to a bone to be lengthened and an adjustment device with two fastening parts that are displaceable relative to one another, each of which is intended for arrangement at a part of the bone to be lengthened, wherein the adjustment device is able to distract the two fastening parts and comprises a drive element with a permanent magnet arranged in rotationally fashion and a mechanism which converts a rotational movement of the permanent magnet into a distracting longitudinal movement of the adjustment device; and an extracorporeal drive unit for the drive element of the implant component. The extracorporeal drive unit comprises a rotatably mounted extracorporeal magnetic ring with an interior to receive the bone to be lengthened with the adjustment device, and an actuation device to rotate the extracorporeal magnetic ring in the ring plane thereof.
