Abstract: In an illustrative embodiment, a dual mode, high-sensitivity, and low-cost applicator array based on split-ring resonators (SRR) and microstrip coupled lines serves as both an imaging and treatment tool for skin cancers. The applicator array consists of 3×3 unit cells, in which each unit in a row is tuned to a separate frequency, ranging from 8 to 15 GHz (unloaded). Via fences surrounding the unit cells provide E-field shielding and enhance resonance. The excitation is coupled magnetically from microstrip to SRRs and generates strong E-fields across the gap between SRR loop terminals. By observing the resonance shift and attenuation under different material under test (MUT), skin in one case, permittivity differences can be analyzed to distinguish malignancies from healthy tissue. Using the same applicator array, hyperthermia capability requires less than 5 W of power to cause significant temperature elevation.

Abstract: A method and system delivers microwave energy to a vessel, such as a vein for the treatment of varicose veins, in a controllable heating pattern and to provide relatively fast heating and ablation of the vessel. The method and system comprises a microwave delivery device for heating the vessel, and a microwave power source for supplying microwave power to the delivery device. The method and system may also include a cooling system, a temperature monitoring, feedback and control system, an ultrasound or other imaging device, and/or a device for assuring generally uniform energy delivery in the vessel.

Abstract: A medical instrument or device is used for resonant delivery of microwave power to tissue for the purpose of resection and coagulation of vessels during surgery and/or other medical procedures. The device enables delivery of large amounts of power to tissue without the need for ground pads by accomplishing an impedance match between tissue and the characteristic impedance of the waveguide that feeds power to it. The device includes a semi-rigid coaxial cable having a center conductor which protrudes from an outer conductor by a length set to be a ?/4 (quarter-wavelength) at the frequency of excitation in the dielectric environment of the tissue of interest. The coaxial cable is shrouded by a dielectric sleeve that provides both thermal and electrical insulation. Fitted against this sleeve is a conductive sleeve whose length is set to be a ?/4 (quarter-wavelength) at the frequency of excitation in the dielectric environment of the dielectric sleeve and the shroud.

Abstract: A method of fabricating high aspect ratio micromechanical tips is provided. The method includes, but is not limited to, forming an etchant protective island on a surface of a silicon substrate with the silicon substrate exposed around the island; isotropically etching the silicon substrate by reactive ion etching around the protective island to partially undercut the silicon substrate beneath the protective island; anisotropically etching, by deep reactive ion etching, the silicon surrounding the island to a desired depth to define a tip shaft of the desired height supported at a base by the substrate; removing the protective island from the tip; and sharpening the top of the tip shaft to an apex. Using the method, micromechanical tips having heights greater than at least 30 ?m have been obtained while maintaining the vertical sidewall necessary for both AFM and scanning near-field microwave microscopy (SNMM) profiling applications.

Abstract: A cooling device comprises a thermally conductive material preferably having a large surface area, such as a plurality of fins. The cooling device clamps or slides onto an energy-introducing cannula and can exchange heat with the surrounding air, or with a coolant enclosed in a camber or shroud around the cooling device. The coolant can be circulated via a pump connected to the shroud. The device and/or shroud can be stabilized and positioned by a positioning cone or spacer. The cooling device and method reduces, minimizes or eliminates thermal effects at critical points along the cannula, while enabling the distal end of the cannula, at which treatment is occurring, to reach a temperature sufficient to kill tumor cells.

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.
