摘要: An ablation apparatus for ablating an inner layer in an organ or lumen of a body, or any desired thin layer, includes an expandable member made of a material with a porous exterior surface. An electrolytic solution, housed in an interior of the expandable member, releases electrolytic solution through the porous exterior surface. A conforming member, which can be an open cell foam material, has an RF conductive surface, and a back side in a surrounding relationship to an exterior surface of the expandable member. Further, the conforming member includes non-zone areas that have a first porosity rate for delivering electrolytic solution to the inner layer. The conforming member also includes a zone for housing each RF electrode and electrolytic solution. Zones have a second porosity rate that is less than the first porosity rate, thus permitting electrolytic solution to pass through the non-zone areas at a faster rate than in the zones. The zones provide an area where electrolytic solution is heated to a higher temperature, due to the differences in porosity with the non-zones. With the combination of the electrode and the heated electrolytic solution in each zone, a larger electrode is created, and there is a more effective, and even application of both RF and thermal energy to the tissue site, such as the endometrium.

摘要: 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.

摘要: An RF treatment system includes first and second catheters with first and second needle electrodes positioned at least partially in lumens of the first and second catheters. Each electrode is surround by a insulator sleeve which is slideable along the electrode and defines an ablation surface. An RF power source is coupled to the first and second needle electrodes. The electrodes provide bipolar RF ablation between the two, defining an ablation volume. A deflectable introducer has a laterally deflectable distal end and an ablation volume temperature sensor positioned at the distal end. The deflectable introducer is advanced in and out of the electrodes distal ends to measure a temperature of tissue in the ablation volume. The treatment system can include more than two electrodes, such as two pairs of electrodes. Further, the system can include a needle electrode extension with a laterally deflectable distal end. The needle electrode extension is positioned in at least one of the distal ends of one of the needle electrodes. It is advanced in and out of the needle electrode distal end to provide monopolar ablation. Additionally, the RF treatment system provides for the introduction of an infusion media, including but not limited to a chemotherapeutic agent, through distribution ports in the needle electrodes, or through one or more infusion devices that can house the needle electrodes and their respective catheters.

摘要: An RF treatment apparatus includes a catheter with a catheter lumen. A removable needle electrode is positioned in the catheter lumen in a fixed relationship to the catheter. The needle electrode includes a needle lumen and a needle electrode distal end. A removable introducer is slidably positioned in the needle lumen. The introducer includes an introducer distal end. A first sensor is positioned on a surface of the needle electrode or the insulator. An RF power source is coupled to the needle electrode and a return electrode. An insulator sleeve is slidably positioned around the electrode and includes a second sensor. Resources are associated with the electrodes, sensors as well as the RF power source for maintaining a selected power at the electrode independent of changes in current or voltage.

摘要: A method and an apparatus for delivering controlled heat independently on separate channels to perform ablation to treat benign prosthetic hypertrophy or hyperplasia (BPH). The dual channel power system provides independent control of radio frequency energy to each of two stylets protruding from a catheter into a human prostate through the urethra. The energy is independently transferred directly into the respective tissue around the stylets in such a manner as to provide respective tissue ablation without damage to surrounding tissues. Automatic shut-off of both channels occurs when any one of a number of surrounding areas to include the urethra or surrounding mass or the adjacent organs exceeds predetermined safe temperature limits. Automatic shut off of the individual channels occurs when the temperature of the tissue proximal to the respective stylet exceeds respective predetermined values. The dual channel system is microprocessor controlled and contains self-test startup and thermocouple autocalibration circuitry.

摘要: A method and an apparatus is disclosed for delivering controlled heat to perform ablation to treat the benign prosthetic hypertrophy or hyperplasia (BPH). According to the method and the apparatus, the energy is transferred directly into the tissue mass which is to be treated in such a manner as to provide tissue ablation without damage to surrounding tissues. Automatic shut-off occurs when any one of a number of surrounding areas to include the urethra or surrounding mass or the adjacent organs exceed predetermined safe temperature limits. The constant application of the radio frequency energy over a maintained determined time provides a safe procedure which avoids electrosurgical and other invasive operations while providing fast relief to BPH with a short recovery time. The procedure may be accomplished in a doctor's office without the need for hospitalization or surgery.
