Abstract: A method 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 method includes taking a catheter having a distal portion with an expandable member and an energy delivery device coupled to an energy source for delivering ablative energy and positioning the catheter distal portion through a nostril of a patient into a nasal meatus adjacent a surface of a nasal concha; expanding the expandable member within the nasal meatus so that the expandable member is brought into contact with the surface of the nasal concha; and delivering sufficient ablative energy from the energy delivery device to the nasal concha to ablate at least a portion of the nasal concha.

Abstract: An endocardial ablation and mapping apparatus is introduced into a heart chamber for mapping to detect arrhythmogenic foci, and ablate endocardium at the arrhythmogenic foci. An inflatable, flexible porous membrane is adapted to receive an electrolytic solution, and become inflated to substantially conform a conductive surface of the membrane to the wall of the heart chamber. A membrane support is surrounded by the membrane, and includes a sealed proximal end and a sealed distal end. Each end has an aperture formed therein defining a central lumen in the membrane support that permits blood flow through the support member and the heart chamber. The membrane support is attached to the membrane and is expanded to a non-distensible state when the membrane is inflated. A catheter, with a distal end, is attached to the membrane or the membrane support. The membrane and membrane support are introduced into the heart chamber by the catheter in a non-expanded state, and become expanded to an expanded state by inflating the membrane with the electrolytic solution. A plurality of treatment electrodes, defining a circuit, are formed on an exterior surface of the membrane support. An RF power source is coupled to the treatment electrodes, and a source of electrolytic solution is coupled to the membrane.

Abstract: According to the present invention, an anastomosis catheter with internally mounted cam pieces holding a plurality of curved needles adjacent apertures in the side of the catheter is provided. The curved needles are attached to lengths of suture material which are installed to run along the outer surface of the central cam pieces to their distal end, where they reverse back along the inner core of the catheter. When the central cam pieces are withdrawn, and moved proximally, the cam surface forces the curved needles out the associated apertures. As the catheter is deployed in a hollow organ, such as a human urethra, the curved needles, as they are deployed, grasp the end of the urethra, which then can be held in position for suturing to the bladder. The other end of the suture materials could have straight needles attached to them to facilitate attaching the urethra to the bladder.

Abstract: 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.

Abstract: An RF treatment apparatus provides multi-modality treatment for tumors and other desired tissue masses, and includes an RF indifferent electrode and an RF active electrode. The RF indifferent electrode has a compacted, non-deployed state, and an expanded deployed state. In the deployed state, the RF indifferent electrode forms a helical structure with four or less coils that surround an exterior of the tumor. The indifferent electrode becomes a microwave antenna when it is coupled to a microwave source. RF ablation energy is delivered to the tumor by the RF active electrode after it has been introduced into the tumor. Both electrodes are coupled to an RF energy source. The indifferent electrode is coupled to a microwave source. Either or both of the electrodes is hollow and include fluid distribution ports for the purpose of providing a chemotherapeutic agent to the tumor site. Ablation energy is supplied to the tumor by the active electrode. The RF indifferent electrode then is switched and becomes a microwave antenna, providing hyperthermia to the tumor and surrounding area. Thereafter, a chemotherapeutic agent is supplied to the tumor site.

Abstract: A medical probe device including a catheter having a stylet guide housing with one or more stylet ports in a side wall thereof and guide means for directing a flexible stylet outward through the stylet port and through intervening tissue to a target tissue. The catheter assembly includes a stylet guide lumen communicating with the stylet port and a stylet positioned in said stylet guide lumen for longitudinal movement from the port through intervening tissue to a target tissue. The stylet can be an electrical conductor enclosed within a non-conductive layer, the electrical conductor being a radio frequency electrode. In normal action, the stylet and its surrounding sleeve are deployed out from the stylet port in the catheter into the desired target tissue. A sharpened tip on the stylet electrode facilitates the penetration of the intervening tissue, such as a urethra. If, however, the stylet is deployed into a dense or fibrous area of tissue or into an area of scar tissue in the urethra, the sharpened tip of the stylet might not immediately penetrate the urethra wall until sufficient pressure is applied to the stylet. By heating the stylet prior to extension of the stylet from the stylet port in the catheter, the passage of the stylet through the intervening tissue is facilitated. Once the stylet is in position in the target tissue, the normal operation of the stylet in emitting electromagnetic current for tissue ablation is commenced.
