Device and method for generating a plasma jet

The invention relates to a device (10) for generating a plasma jet (P) comprising a first conduit (11) inside a second conduit (12), a first electrode (17) and a second electrode (18) for generating an electric field in a feed gas flow (F) provided in a first flow channel (15) to generate a plasma jet (P), and adapted to provide a curtain gas flow (C) in the space between the first and second conduit (11,12), wherein the first electrode (17) is positioned radially outside of the first flow channel (15), and wherein the radial distance of the second electrode (18) from a longitudinal axis (l) is larger than the radial distance of the first electrode (17) from said longitudinal axis (l). The invention further relates to an endoscope comprising a device (10), a method for generating a plasma jet (P), a method and a use of the device (10) for manipulating a cavity.
