International Classification:
A61B 18/18, A61N 1/00
US Classification:
606033000, 607156000
Abstract:
A method and device delivers microwave power to an antenna through a coaxial cable utilizing air or other gases as its dielectric core. The cable includes supports made of low-loss materials to keep the inner conductor centered in the cable, and defining spaces therebetween for the air or gas. Channels in the supports allow the air or gas to circulate in the cable. The gas may be chilled or cooled to provide an addition level of heat dissipation. The device enables delivery of large amounts of power to tissue without undue heating of the feed cable or peripheral tissues, and without increasing the diameter of the feeding cable or antenna, keeping the antenna safe for percutaneous use.

International Classification:
A61B018/14
US Classification:
606041000
Abstract:
Efficient ablation with multiple prong electrodes is obtained by electrically isolating the prongs from each other and rapidly switching electric power between the prongs, between a prong and a ground pad, or both. In this way, power distribution to a tumor can be controlled efficiently without the need to change probe geometry.

International Classification:
A61B018/18
US Classification:
606/032000, 606/041000
Abstract:
In radiofrequency ablation, larger lesion volumes are obtained for a given energy delivery by energizing at least two electrodes on either side of the tumor so that current is focused between them rather than dispersed radially to a large area ground plate. Modified standard umbrella probes may be used or a specialized dual electrode array may be fabricated for simplified use. Differential impedance between tumor and non-tumor tissues at certain frequencies is exploited to further improve lesion shape and size.
