Title: (DE) VORRICHTUNG UND VERFAHREN ZUR ABLATION MITTELS EINER TRANSURETHRALEN KANÜLE.
(EN) TRANSURETHRAL NEEDLE ABLATION DEVICE AND METHOD.
(FR) PROCEDE ET DISPOSITIF D'ABLATION A AIGUILLE TRANSURETRALE.
Abstract:
(EN) A transurethral needle ablation device (31) for the treatment of the prostate of a human male using radio frequency energy comprising a sheath (32) having a lumen (36) extending therethrough. A guide tube assembly (51, 52) is slidably mounted in the lumen in the sheath and having a lumen extending therethrough. A needle electrode (116) is slidably mounted in the lumen (84) in the guide tube assembly. An insulating sheath (83) is disposed about the needle electrode so that the distal extremity of the needle electrode is exposed, whereby when the sheath is positioned in the urethra with its distal extremity in the vicinity of the prostate, the needle electrode can be advanced through the urethral wall and into the tissue of the prostate to permit the application of radio frequency energy to the tissue of the prostate surrounding the needle electrode to form a lesion in the prostate.
(FR) Dispositif (31) d'ablation à aiguille transurétrale destiné au traitement de la prostate d'un homme au moyen d'une énergie haute fréquence, et comprenant une gaine (32) à travers laquelle s'étend une lumière (36). Un ensemble tube de guidage (51, 52), monté coulissant dans la lumière de la gaine, est également traversé par une lumière. Une aiguille-électrode (116) est montée coulissante dans la lumière (84) de l'ensemble tube de guidage. Une gaine isolante (83) est disposée autour de l'aiguille-électrode de façon à en exposer l'extrémité distale, de sorte que, lorsque la gaine est placée dans l'urètre, et que son extrémité distale se trouve dans la région de la prostate, l'aiguille-électrode peut être amenée à passer à travers la paroi urétrale dans les tissus de la prostate afin de permettre l'application d'une énergie haute fréquence aux tissus de la prostate entourant l'aiguille-électrode pour produire une lésion dans la prostate.
