Abstract: A biocompatible, resorbable composite for osteosynthesis includes osteoconductive particles dispersed within a porous polymer matrix having a plurality of fluid passageways that expose at least a portion of a plurality of the osteoconductive particles to an exterior of the polymer matrix. The composite may further include a chemical additive incorporated within the polymer matrix, the chemical additive being configured to modify one or more of acidity, degradation rate, melting point, hydrophilicity, and hydrophobicity of the polymer matrix. A method for making the composite includes mixing the osteoconductive particles with polymer material and the chemical additive to form a mixture and treating the mixture to bind the osteoconductive particles with the polymer material to create a solid unit.

Abstract: In an arrangement for generating a local electron-cyclotron-microwave-low pressure plasma at a certain location within a gas-filled process chamber, a microwave supply means providing a microwave beam and a plasma localization unit generating a magnetic field are provided such that the magnetic field and the microwave beam intersect each other in the process chamber. The microwaves are uncoupled onto a concave reflection structure from the focal point thereof so that the microwave beam generated is essentially parallel. An arrangement for generating a magnetic field is movable along the microwave beam axis so that a cross volume between the microwave beam and the magnetic field can be moved along the beam axis whereby the conditions for electron cyclotron resonance are adjustable by displacement of the magnetic field.
