Abstract: An ablation electrode carries a temperature sensing element for measuring the temperature of the tissue being ablated. A thermal insulating element associated with the sensing element blocks the transfer of heat energy from between the temperature sensing element and the body. The temperature sensing element therefore measures temperature without being affected by the surrounding thermal mass of the electrode.

Abstract: An ablation apparatus has a multiple antenna device of adjustable length including an adjustable length primary antenna and an adjustable length secondary antenna. The primary antenna has a longitudinal axis, and the secondary antenna is deployed in a direction lateral to the longitudinal axis. The secondary antenna is constructed to be structurally less rigid than the primary antenna. The adjustable lengths of the primary and secondary antennas permits a desired geometric ablation of a selected tissue mass. An adjustable insulation sleeve is positioned on an exterior of one of the primary or secondary antennas. An energy source is connected to the multiple antenna device. A variety of energy sources can be used including RF, microwave and laser.

Abstract: An apparatus and method are provided for control contraction of tissue that includes collagen fibers. The apparatus includes a handpiece, and an electrode with an electrode proximal end associated with the handpiece. A distal end of the electrode has a geometry that delivers a controlled amount of energy to the tissue for a desired contraction of the collagen fibers. This is achieved while dissociation and breakdown of the collagen fibers is minimized. The handpiece, with electrode, is adapted to be introduced through an operating cannula in percutaneous applications. Additionally, an operating cannula may be included in the apparatus and be attached to the handpiece. The apparatus and method provides for a desired level of contraction of collagen soft tissue without dissociation or breakdown of collagen fibers.

Abstract: An ablation apparatus has an expandable member that is inserted into an organ of a body and ablates all or a selected portion of the inner layer of the organ. Electrolytic solution fills the expandable member, and the expandable member includes a plurality of apertures from which electrolytic solution flows from the expandable member. First and second fluid conduits, which can be first and second conforming members, are in a surrounding relationship to the expandable member. The second conforming member, including a conductive surface, is made of a material that provides substantial conformity between the conductive surface and a shape of the inner layer of the organ. A plurality of electrodes is positioned between the two conforming members. The expandable member serves as an insulator to RF energy. Each electrode includes an insulator formed on a surface of the electrode positioned adjacent to the second conforming member. The combination of sandwiching the electrodes between the two conforming members, and the use of two insulators, one on the electrode and the other on the expandable member, provides selectable ablation of the inner layer of the organ. A feedback device is included and is responsive to a detected characteristic of the inner layer. The feedback device provides a controlled delivery of RF energy to the electrodes.

Abstract: An ablation apparatus has a balloon that is inserted into an organ of a body and ablates all or a selected portion of the inner layer of the organ. Electrolytic solution fills the balloon, and the balloon includes a plurality of apertures from which electrolytic solution flows from the balloon. The flow rate of electrolytic solution is dependent on the pressure applied to the balloon by the electrolytic solution. A conforming member, with a conductive surface and a back side, is made of a material that substantially conforms to a shape of the inner layer of the organ and delivers the electrolytic solution and RF energy through the conductive surface to the inner layer. Advantageously, difficult to access areas are reached with the inclusion of the conforming member. Optionally positioned between the conforming member and the balloon is a porous membrane. A printed circuit is printed in or on the conforming member and delivers RF energy to selected sections of the inner layer. The printed circuit provides for the monitoring of impedance, temperature and circuit continuity. Additionally, the printed circuit can be multiplexed.

Abstract: An improved probe for cardiac diagnosis and/or treatment includes a control handle and a catheter for insertion into the heart. The catheter has a distal end, a proximal end and at least one lumen connecting said distal and proximal ends. It also includes a flexible inner tube and an outer sheath enveloping said tube. At least one measuring electrode or ablation device is attached to the distal end of the tube. The outer sheath and the inner tube are rotatable relative to each other so that the electrode or device can be rotated within the heart without rotating the outer sheath. The sheath is also axially movable relative to the tube to selectively enclose or expose the electrode or device for use.

Abstract: An apparatus and method are provided for control contraction of tissue that includes collagen fibers. The apparatus includes a handpiece, and an electrode with an electrode proximal end associated with the handpiece. A distal end of the electrode has a geometry that delivers a controlled amount of energy to the tissue for a desired contraction of the collagen fibers. This is achieved while dissociation and breakdown of the collagen fibers is minimized. The handpiece, with electrode, is adapted to be introduced through an operating cannula in percutaneous applications. Additionally, an operating cannula may be included in the apparatus and be attached to the handpiece. The apparatus and method provides for a desired level of contraction of collagen soft tissue without dissociation or breakdown of collagen fibers.
