    摘要： A light diffuser, which is particularly suitable for introducing diffuse light into a tissue, is produced by interpenetration of a diffuser material in a liquid state into a boundary layer of a porous shaping material, by which process a diffuser surface is formed having a surface structure which represents essentially a negative of the pore structure of the shaping material and includes undercut structures induced by a surface tension. The light diffuser is e.g. produced by introducing a diffuser blank including material that is liquefiable through mechanical vibration into the shaping material and simultaneously stimulating it with mechanical vibrations, such that the liquefiable material liquefies at least there where it is in contact with the shaping material and is pressed into the shaping material. An in situ production of the diffuser is particularly advantageous for photodynamic therapy in bone tissue.

    摘要： An EEG headpiece includes an array of electrode pins, each electrode pin extending between a proximal end, formed by a proximal end face, and a distal end and including a conducting electrode and a thermoplastic material. The thermoplastic material is arranged at least around a periphery of the electrode pin or is pressable from a hollow space to the periphery. Each electrode pin is equipped for the transmission of energy, especially mechanical vibration energy, from the proximal end face to the thermoplastic material to liquefy at least portions of the thermoplastic material from a solid state to a flowable state, whereby the thermoplastic material is capable of flowing into structures of a tissue portion surrounding the periphery and of forming, after re-solidification of the thermoplastic material, an anchoring of the electrode pin in the tissue portion.

    摘要： A method of anchoring a connector in a first object is provided, wherein the connector includes thermoplastic material in a solid state. The method includes bringing the connector into physical contact with the first object, rotating the connector relative to the first object around a proximodistal rotation axis and exerting a relative force by the connector onto the first object, until a flow portion of the thermoplastic material of the connector becomes flowable and flows relative to the first object, and stopping rotation of the connector, whereby the flow portion anchors the connector relative to the first object, wherein a distal end of the connector is equipped for cutting/punching into the first object and/or for removing material therefrom.
