  • Publication number: 20030208250
    Abstract: An atrioventricular valve tissue ablation catheter (2), especially suited for treating Mahaim fibers, includes a shaft (4) with a deflectable tip (20) at the distal end (6) and a handle (10) at the proximal end (8). The tip includes a distal segment (66) curving in one direction and a proximal segment (44) curving in the opposite direction so the distal segment causes the distal segment can engage tissue on either side of the annulus (92) of the tricuspid (or mitral) valve (90). Ablation energy can be supplied through the ablation electrodes (46, 70) simultaneously or one at a time to ablate tissue at the annulus without the need for moving the catheter. Mapping electrodes (38) are provided proximal of the ablation electrodes.

  • Publication number: 20030153905
    Abstract: Structures, processes, and mechanisms are provided for the ablation of hollow organs. Ablation structures, having deployable electrically conductive probes, are placed within a hollow organ, such as a stomach. The ablation structure typically includes a distension mechanism, whereby the hollow organ is controllably distended. The electrically conductive probes are then deployed, such that the probes extend make electrical contact with the tissue of the hollow organ, typically by extending through a mucosal layer of the hollow organ. The electrically conductive probes are typically deployed by extension of movable electrically conductive probes, from a first protected position to a second extended position. In alternate embodiments of the ablation system, the ablation apparatus includes means for vacuum-directed contact between the tissue and the electrically conductive probes.
