摘要： A radio frequency energy transmission device comprises a hollow coaxial electrically conductive cable adapted for conduction of radio frequency (RF) energy, particularly microwave energy, for the ablation of biological tissue. The hollow cable has a proximal end and a distal end and comprises coaxial inner and outer conductors extending substantially the entire length of the cable from the proximal end to a distal end portion of the cable. The inner conductor comprises an elongated electrically conductive tubular member having a hollow, axially extending lumen, and the outer conductor comprises an elongated electrically conductive tubular member disposed in a substantially coaxial relationship over at least a portion of the inner conductor. Dielectricity to impede conduction between the inner and outer conductors is introduced with a vacuum or dielectric medium disposed between the inner and outer conductors. An ablating member, which delivers radio frequency energy, particularly microwave energy, to body tissue is disposed at a distal end portion of the cable. The ablating member can be a helical coil, a monopole of a microstrip circuit.

摘要： An improved radio-frequency catheter system for ablating biological tissues of a body vessel in a patient including a catheter, a deployable antenna guide disposed at the distal portion of the catheter and a radio-frequency (“RF”) antenna mounted on the antenna guide. The RF antenna includes a axial passageway to accommodate the antenna guide, and is adapted to receive and transmit RF energy for tissue ablation. Upon deployment, the antenna guide acquires a loop configuration which establishes line contact with the body vessel conformable to its internal contour to prescribe the precise and affixed tissue ablation pathway despite body vessel movements. The RF antenna is carried by the antenna guide to be deployed along the established tissue ablation pathway. Alignment of the loop with the desired tissue ablation pathway is facilitated with the use of radio-opaque markers and intracardiac electrodes mounted along the antenna guide. The catheter, as well as the antenna can be provided with steering or deflection mechanism for navigation through the body vessel passageways. A hollow co-axial cable is provided for the delivery of RF energy.
