Abstract: front page image
(EN)A surgical ablation probe assembly (10) particularly suitable for ablating tissue on a surface of a patient's heart having an ablation member (11) and a stabilizing member (12) for guiding the probe assembly to an intracorporeal location such as a surface of the patient's heart. The elongated ablation member generally has at least one ablation electrode (16) on a distal shaft section (15). The stabilizing member (12) has a vacuum lumen (30) which applies a vacuum to the inner chamber of the stabilizing member to aspirate fluid from within the chamber or about the stabilizing member and can aid in holding the stabilizing member to an intracorporeal surface such as the epicardial or endocardial surface of the patient's heart. The probe assembly may also have a removable stylet to help retain the shape of the distal portion. The assembly is suitable for treating a patient for atrial arrhythmia, by forming linear or curvilinear lesions and preferably a continuous lesion on the surface of the patient's heart.
(FR)Ensemble sonde d'ablation chirurgical (10) particuliErement conçu pour rEaliser l'ablation de tissus sur une surface du cOEur d'un patient, prEsentant un ElEment d'ablation (11) et un ElEment de stabilisation (12) pour guider l'ensemble sonde jusqu'à un endroit situE A l'intErieur du corps, tel qu'une surface du cOEur du patient. L'ElEment d'ablation allongE possède gEnEralement au moins une Electrode d'ablation (16) sur une partie de tige distale (15). L'ElEment de stabilisation (12) possède une lumière A vide (30) qui applique un vide dans la chambre intErieure de l'ElEment de stabilisation pour aspirer du fluide à l'intErieur de la chambre ou autour de l'ElEment de stabilisation et peut contribuer A maintenir l'ElEment de stabilisation sur une surface intracorporelle, telle que la surface Epicardiaque ou la surface endocardiaque du cOEur du patient. L'ensemble sonde peut Egalement comporter un stylet amovible conçu pour aider A conserver la forme de la partie distale. L'ensemble convient au traitement d'un patient souffrant d'arythmie atriale, par formation de lEsions linEaires ou curvilinEaires et, de prEfErence, une lEsion continue, sur la surface du cOEur du patient.
