Abstract: An apparatus is provided for ablating at least a portion of a nasal concha. By ablating at least a portion of a nasal concha, the size of the nasal concha is reduced. The three nasal concha in the body (inferior, middle and superior nasal concha) form at least a portion of the three nasal meatus (inferior, middle and superior nasal meatus) in the body. By reducing the size of a nasal concha, obstruction of a nasal meatus is reduced or eliminated. As a result, air flow through the nasal meatus is improved. In one embodiment, the apparatus includes a catheter having a distal portion with a dimension configured for positioning the catheter distal portion through a nostril of a patient into a nasal meatus adjacent a surface of a nasal concha and a means at the catheter distal portion for delivering sufficient ablative energy to the nasal concha to ablate at least a portion of the nasal concha through heating without penetrating the surface of the nasal concha with an element of the apparatus.

Abstract: 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.

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 can be formed in or on the conforming member, or adjacent to its back side or conductive surface, and delivers RF energy to selected sections of the inner layer. 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 segments of the circuit.

Abstract: A cardiac diagnosis and treatment system comprises a support carrying at least two electrodes. A conductor is associated with the support for selectively directing electrical signals to and from each electrode. The conductor includes a first buss for delivering power from an external power source, a second buss for transmitting electrode signals to an external signal processor, and a third buss for receiving control signals from an external signal source to multiplex the electrode signals from the electrodes through the second buss. A conduction line conducts power, control signals, and electrode signals from the external sources to the conductor.

Abstract: An electrode tip assembly for a catheter is bendable under the control of the user. One portion of the assembly is more resistant to bending than the remaining portions. The variable stiffness directs and concentrates the applied bending forces in the particular region where maximum bending is desired.

Abstract: A catheter has a handle and a guide tube enclosing an interior bore. The guide tube has a proximal end and a distal end. A friction sleeve joins the proximal end of the guide tube to the handle. The friction sleeve extends from the handle and grips a portion of the guide tube beyond the handle. The friction sleeve forms a hand grip for the user beyond the confines of the handle. It also serves to effectively transmit torque applied at the handle to the distal end of the guide tube.
