  • Publication number: 20230329782
    Abstract: A catheter includes a hollow shaft; a distal end electrode provided on a distal end portion of the hollow shaft; a proximal end electrode provided on a proximal end portion of the hollow shaft, and which is electrically connected to the distal end electrode via the hollow shaft; and a connection portion which is capable of being attached to and detached from the proximal end electrode and which, by being attached to the proximal end electrode, electrically connects an external voltage output device and the proximal end electrode via a lead wire.

  • Publication number: 20230329781
    Abstract: A plasma ablation system includes a plasma guide wire having a conductive first electrode formed on a distal end portion, a catheter having a conductive second electrode formed on a distal end side and a lumen through which the plasma guide wire is inserted, and a radio frequency (RF) generator electrically connected to each of the plasma guide wire and the catheter to output a high frequency electric power to the first electrode and the second electrode. The plasma guide wire can ablate a living body tissue by discharge between the first electrode and the second electrode, and the RF generator outputs the high frequency electric power that is 50 W or higher and 100 W or lower during discharge and pulse-modulated to have a duty ratio of 7.4% or higher and 40.0% or lower.

  • Publication number: 20230284996
    Abstract: A FPD navigation device includes an image acquiring portion that acquires, from a FPD (flat panel detector), a first image including an image of a target blood vessel taken at a first position, and a second image including an image of the target blood vessel taken at a second position different from the first position; a position information acquiring portion that acquires position information on the target blood vessel from the first image, the second image, position information on the first position, and position information on the second position; and a recommendation range output portion that outputs, from the position information on the target blood vessel, a FPD imaging position recommendation range representing a range of an imaging position of the FPD recommended for acquiring an image of the target blood vessel.

  • Publication number: 20210052321
    Abstract: A catheter comprises a shaft, an extended shaft portion, and an electrode disposed on an outer circumferential surface of the shaft. The shaft has a first lumen and a second lumen that is arranged adjacent to the first lumen. The extended shaft portion is provided on a distal end portion of the shaft, has the first lumen, and has a distal end portion located on a distal end side of a distal end portion of the second lumen, in the shaft.

  • Publication number: 20190259172
    Abstract: Provided is a technique for detecting whether or not there is a drop of a liquid in a non-supply period. There are performed the steps of: imaging in a non-supply period during which supply of liquid to a target nozzle among one or more nozzles is stopped while allowing an imaging visual field to include a dropping path through which the liquid drops from an opening of the target nozzle; and detecting whether or not there is a drop of the liquid using an imaging result in the imaging step. This enable detecting whether or not there is a drop of the liquid from the target nozzle in a non-supply period during which supply of the liquid toward the target nozzle is stopped.
