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 endocardial ablation apparatus, for introduction into a heart chamber formed by a wall, is provides. The ablation apparatus includes an inflatable, flexible porous membrane adapted to receive an electrolytic solution, and become inflated to substantially conform an exterior surface of the membrane to the wall of the heart chamber. An inner lumenal member is surrounded by and attached to the membrane. The inner lumenal member includes a lumen that permits blood flow through the inner lumenal member and heart chamber. An introducer catheter introduces the membrane and inner lumenal member into a selected heart chamber. A plurality of RF electrodes define a circuit positioned in the membrane or on an exterior surface of the inner lumenal member. The RF electrodes transfer thermal energy to the electrolytic solution. The electrolytic solution is the electrode that provides ablation of a selected site of the heart chamber. An RF power source is coupled to the RF electrodes. A source of electrolytic solution is coupled to the membrane.

Abstract: A medical probe apparatus comprising a catheter having a stylet guide housing with at least one stylet port in a side thereof and a stylet guide for directing a flexible stylet outward through at least one stylet port and through intervening tissue to targeted tissues. The stylet guide has a biopsy sample device or other tissue manifesting device at the distal end thereof to gather tissue or perform other operations at the point of the desired tissue such as emitting electromagnetic energy as ablative power to target tissues.One embodiment of the biopsy sample stylet includes a hollow core sampler including a biopsy needle apparatus for gathering sample tissue. The hollow core sampler has a sharpened end for facilitating the penetration into and gathering of the sample tissue. A second embodiment of the biopsy sample stylet includes a harpoon-like sample stylet when the sharp tip thereof allows for easy entry into the target tissue. The sharpened barbed side opening allows for certain desired tissue to be sampled to be drawn into the side opening for individual cell gathering or complete sample excise or gathering of the desired tissue. The third embodiment is a clam shell or alligator type biopsy jaw device whereby the sharpened biopsy tip thereof allows a tissue sample to be clipped or cut upon activation of the stylet jaws. Still another embodiment comprises a biopsy knife device in conjunction with an electromagnetic emitter for selective tissue sampling or electromagnetic heat ablation, or both, of selected tissue.

Abstract: 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.
