摘要： A tissue ablation apparatus includes a delivery catheter with distal and proximal ends. A handle is attached to the proximal end of the delivery catheter. At least partially positioned in the delivery catheter is an electrode deployment device. The electrode deployment device includes a plurality of retractable electrodes. Each electrode has a non-deployed state when it is positioned in the delivery catheter. Additionally, each electrode has a distended deployed state when it is advanced out of the delivery catheter distal end. The deployed electrodes define an ablation volume. Each deployed electrode has a first section with a first radius of curvature. The first section is located near the distal end of the delivery catheter. A second section of the deployed electrode extends beyond the first section, and has a second radius of curvature, or a substantially linear geometry.

摘要： A tissue ablation apparatus includes a delivery catheter with distal and proximal ends. A handle is attached to the proximal end of the delivery catheter. At least partially positioned in the delivery catheter is an electrode deployment device. The electrode deployment devices includes a plurality of retractable electrodes. Each electrode has a non-deployed state when it is positioned in the delivery catheter. Additionally, each electrode has a distended deployed state when it is advanced out of the delivery catheter distal end. The deployed electrodes define an ablation volume. Each deployed electrode has a first section with a first radius of curvature. The first section is located near the distal end of the delivery catheter. A second section of the deployed electrode extends beyond the first section, ad has a second radius of curvature, or a substantially linear geometry.

摘要： An apparatus that reduces a volume of a selected site in an interior of the tongue includes a handpiece means and an electrode means at least partially positioned in the interior of the handpiece means. The electrode means includes an electrode means electromagnetic energy delivery surface and is advance able from the interior of the handpiece means into the interior of the tongue. An electrode means advancement member is coupled to the electrode means and configured to advance the electrode means an advancement distance in the interior of the tongue. The advancement distance is sufficient for the electrode means electromagnetic energy delivery surface to deliver electromagnetic energy to the selected tissue site and reduce a volume of the selected site without damaging a hypoglossal nerve. A cable means is coupled to the electrode means.
