Abstract: The present invention relates to supramolecular biomedical polymers comprising quadruple hydrogen bonding units and to a process for preparing such a supramolecular biomedical polymer and porous biomedical implants thereof. The supramolecular biomedical polymers are particularly suitable for the production of porous biomedical implants that need high strength, elasticity, durability, and slow biodegradation, e.g. medical implants for living tissue regeneration within a mammal, such as the treatment of cardio-vascular diseases, medical prolapses, and hernias.

Abstract: A coil assembly has at least two coils which are arranged in a common plane, and partially overlap in crossover sections of the coils. The crossover sections have a reduced height, which results in a reduced total height of the coil assembly. This leads to a more compact coil assembly, and hence to better dynamic characteristics of a positioning device in which the coil assembly is applied.
