Abstract: The present invention refers to a plasma jet device (30) for medical treatment of root canals (3) using an atmospheric pressure plasma. The device comprises a handle (40) and a probe (50) with a gas channel (54) and a first and second electrode (31, 32). The probe (50) has a first end connected to the handle (40) and a second end opposite to the first end being a probe tip. The first electrode (31) extends to the probe tip. The first electrode (31) is a hollow outer electrode and the second electrode (32) is an inner electrode extending at least along a section of the first electrode (31) inside the first electrode (31). The second electrode (32) except for a portion at its end is surrounded by a dielectric material (33). The probe (50) is adapted to be inserted into a root canal (3). The plasma jet device (30) is adapted to provide negative pulses at the second electrode (32) for producing the atmospheric pressure plasma at the tip of the second electrode (32).

Abstract: The invention relates to an electrode arrangement for a plasma jet device comprising a first and a second printed circuit board each having an exposed surface of a circuit path serving as electrode and facing the other printed circuit board, a spacer arranged between the first and second circuit board and a plasma cell arranged between the first and second printed circuit board and the spacer wherein the plasma cell has a gas inlet and a plasma outlet.

Abstract: A method for coating a medical implant applies at least one coating to at least one surface of the implant by plasma polymerization. The implant has pores sized in the nanometer range. The method stabilizes the pores. The plasma polymerization is conducted in the presence of a coating gas and oxygen. A coating parameter can be selected so that a rough surface of the implant is coated. An implant includes a membrane having pores sized in the nanometer range. A surface of the implant is at least partially coated with a plasma polymer. The interior of the pores is uncoated.
