  • Patent number: 10531908
    Abstract: A method for heat treating biological tissues includes providing a pulsed energy source having energy parameters selected so as to raise a target temperature to a level to achieve a therapeutic effect, while the average temperature rise of the tissue over a prolonged period of time is maintained at or below a predetermined level so as not to permanently damage the target tissue. Application of the pulsed energy source to the target tissue induces a heat shock response and stimulates heat shock protein activation in the target tissue so as to therapeutically treat the target tissue.

  • Patent number: 10406031
    Abstract: An applicator configured for cell treatment with pressure pulses has a hollow needle with a wall, which encloses a cavity and has a closed-off design at a closed-off end. A target is arranged or formed at the closed-off end on the inner side of the wall and a laser radiation emitter for emitting preferably pulsed laser radiation is arranged in the cavity of the hollow needle, at a distance from the target. The laser radiation emitter is arranged so that the emerging laser radiation impinges directly on the target through an interspace situated between the laser radiation emitter and the target. Under the formation of a plasma, at least one pressure pulse can be generated at the target by the target being impinged upon by laser radiation from the laser radiation emitter. The wall of the hollow needle has a lateral emergence opening for the emergence of the pressure pulse.

  • Patent number: 10251632
    Abstract: A handle for a surgical instrument, which handle has a carriage designed to move an actuation rod. A second actuation element is arranged adjacent to the first actuation element and is rotatable over the longitudinal axis of the main body. The second actuation element is annular, toward the first actuation element, and carries on its inner circumference a rotationally fixed locking ring. The carriage has a finger which extends, eccentrically with respect to the longitudinal axis of the main body, from a front face of the carriage facing the locking ring. In a locked state, a protuberance on the ring provides an abutment for the carriage. In the release state, the finger is offset with respect to the protuberance, and a range of travel of the carriage is freed.
