  • Publication number: 20250099152
    Abstract: An ablation instrument having a fiber-reinforced thermoplastic plastic pin as well as a seat for s fluid line and a connection surface for the gas junction. The ablation instrument is particularly appropriate as single-use instrument as it is primarily made of plastic.

  • Publication number: 20250057592
    Abstract: An interior cooled ablation instrument includes a curved section adjoining its distal end in which the ablation instrument is bent relative to its axial direction. The amount of the angle is preferably defined to one-third up to two-thirds, and preferably half of the maximum angulation. The maximum angulation can significantly exceed an absolute value of 140°. Due to the pre-bend in the curved section, a kinking of the hose of the ablation instrument and thus an impairment of the electrode cooling as well as the occurrence of high dam pressure can be effectively avoided. In doing so, the ablation instrument allows a freer work, even more considerably oriented at medical aspects and considerations compared to completely stretched ablation instruments.

  • Publication number: 20240115315
    Abstract: An ablation instrument includes one or more electrodes that are configured as helical springs having ends for electrical connection that are configured as axial extensions. The electrodes are located on an inner hose serving as support, wherein the extensions are located at a smaller distance to the longitudinal axis than the windings of the electrode. Between the extension and the winding, a winding section is configured along which the distance toward the longitudinal center axis decreases from the radius of the winding to a lower value, so that the extension is located inward relative to the windings, i.e., closer to the center axis. For receipt of this extension and the associated electrical connection, the inner hose includes a trough.

  • Publication number: 20240115307
    Abstract: A probe having a cutting electrode at its distal end, which is formed on an end piece of probe. From the end piece a wire extends over the entire length of probe therethrough. The wire can serve for current supply to the end piece. The cutting electrode can include a junction site from which electrode surfaces extend away in at least three directions.

  • Publication number: 20240115306
    Abstract: An ablation probe according to the invention comprises at least one electrode, which is held on a hose. The ablation probe is provided with a closure piece from which a wire extends over the entire length and through the hose. A fluid supply line is attached to the wire and has lateral openings for cooling the electrode, the wire being closed at the terminal end. An axial alignment of the openings relative to the electrodes can be achieved due to the fixation of the fluid supply line to the wire, and a misplacement can be avoided.
