An implant is suggested having a receptacle space for a therapeutic agent, which can leave the receptacle space through a permeable element. For exact dosage, an open-pore diffusion element is suggested as the permeable element, wherein the pore walls are chemically modified for control of the diffusion.

Implant with permeable element

The invention relates to an implant and a method for the production of an implant. The implant has a covering layer that is preferably made of aluminium oxide and provided with uniform cavities and separate openings on the surface side of the covering layer in order to receive a therapeutic agent which can be released according to requirements when the implant is in place.

Implant with cavities containing therapeutic agents

An MR-compatible surgical instrument is proposed. A simpler, more economic construction is made possible by the use of aluminum or an aluminum compound or alloy as base material, which is covered by a thin barrier layer of an inorganic oxide.

Surgical instrument

A process and device for the laser treatment of the internal surfaces of hollow bodies such as engine blocks with cylinder bores which consist of the matrix alloys such as a light-metal or aluminum, wherein a wear-resistant coating is applied to the working surfaces of the pistons within the cylinder. A probe enters the cylinder and includes the laser beam which produces a beam spot on the internal surface of the cylinder and applies an alloying powder at the focus of the spot using a continuously conveying protective gas. The probe is displaced along the axis of the cylinder and simultaneously rotated while the alloying powder is melted in the spot of the laser beam to a depth sufficient to form a wear-resistant coating which will not break loose during the normal operation and life of the engine block. The engine block can be fixed in a stationary position while the probe or probes move simultaneously within the cylinders to apply the hardened surface coating.
