Abstract: A granulate mixture suitable for regenerating a bone contains at least one expandable particle and at least one nondeformable particle. The at least one expandable particle contains a swelling agent. The swelling is enclosed by a biodegradable sheathing or be a biodegradable casing. Three-dimensional callus distraction may be accomplished by introducing the granulated mixture into a bone defect.
Abstract: A device for regenerating a bone includes a sheathing and a swelling agent. At least a portion of the sheathing has the shape of a bellows, and/or the exterior of the sheathing bears at least one lamella. The swelling agent is enclosed by the sheathing. The sheathing is biocompatible, expandable, contractible, and/or deformable in a predefined and controlled manner as a function of a force effect induced by a change in volume of the swelling agent.
