Device and method for generating a pulsed anisothermal atmospheric pressure plasma

The invention relates to a device and a method for generating a pulsed (intermittent), cold, atmospheric pressure plasma, preferably a thread, for precise antimicrobial plasma treatment (disinfection, disinfection, sterilization, decontamination) of the smallest areas and cavities, even on living human beings and animal bodies, preferably in the field of medicine, by means of a negative direct current corona discharge with at least one electrode for generating high field strengths, which the gas to be ionized flows through or around in a gas channel, the counter electrode being the electric

Device for treating living cells by means of a plasma

The invention relates to a method and device for treating living cells by means of a plasma (plasmaporation). In addition to conventional devices for generating plasma and generating a field, such as by electroporation, the device comprises devices for mixing and transporting active substances, predominantly in the form of nano and microparticles, for affecting the metabolism of the cells.

Device for the planar treatment of areas of human or animal skin or mucous membrane surfaces by means of a cold atmospheric pressure plasma

The invention relates to a device, preferably a collar, for treating areas of human or animal skin or mucous membrane with a cold atmospheric pressure plasma by creating a dielectrically hindered surface discharge, comprising at least one flexible insulating material (1), a flexible high-voltage electrode (2), a flexible dielectric (3), a flexible grounded electrode (4) and a gas supply (7), characterized in that the flexible high-voltage electrode (2) is embedded in the insulating elastomer (3), having the effect of a dielectric, and the grounded electrode (4) is applied to the elastomer s

Device for the plasma treatment of human, animal or plant surfaces, in particular of skin or mucous membrane areas

The invention relates to a device for the treatment of free-form areas and zones of human or animal skin areas or plant surfaces by means of cold atmospheric-pressure plasma. The core of the device is a specific, preferably gas-permeable, electrode arrangement for generating a dielectrically impeded surface discharge where the earthed electrode is composed of electrically conductive textile material and the high-voltage electrode consists of a thin wire or electrically conductive thread which is sheathed with an insulting layer which has to meet specific requirements.

Antibacterial Surface Modification for Medical Devices

The invention relates to a medical device comprising a biocompatible material having an exposed surface prone to biofilm growth. The biocompatible material comprises a doping of an antibacterial metal compound. A concentration of the doping compound ranges from 1% to 30% (w/w) within an outer layer adjacent to the exposed surface, and is essentially zero within a bulk layer of the biocompatible material.

Multi Frequency Plasma Generating Device and Associated Method

The invention relates to a device (1) for generating a plasma, particularly an atmospheric plasma, comprising: a plasma source (100) having a first electrode (101) and optionally a second electrode (102) being arranged opposite the first electrode (101), and a volume (or channel) (103) arranged adjacent the first electrode (101) for receiving a gas (G), and at least one radiofrequency power supply (200) in electrical contact with said first electrode (101) for applying a radiofrequency voltage (V) thereto.
