Abstract: A method is provided for forming a stent within a body lumen. According to the method, a distal catheter body is advanced within a body lumen to a section of a body lumen at which a stent is to be formed. One or more expandable members attached to the distal catheter body are expanded such that sections of the body lumen proximal and distal to the stent formation section of the body lumen are occluded, the distal catheter body in combination with the body lumen defining a mold space. A fluent pre-stent composition is delivered to the mold space from outside the body lumen which is continuously in fluent state during pre-stent composition delivery from outside the body lumen to the mold space. The fluent pre-stent composition is then transformed within the mold space to a non-fluent stent composition to form a stent within the mold space.

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: An ablation apparatus includes a cannula with a distal end, a proximal end and a lumen. An anvil is coupled to the cannula and extends beyond the cannula distal end. The anvil has a distal end that extends in a lateral direction relative to an anvil longitudinal axis. The distal end is adapted to receive and position an uvula or other soft tissue. One or more energy delivery devices are slideably positioned in the cannula. The energy delivery devices are advanced and retracted in and out the cannula distal end. An advancement and retraction apparatus advances and retracts the energy delivery devices in and out of the cannula distal end and into the soft tissue retained at the anvil distal end. The soft tissue ablation apparatus can further include a handle with a lumen, a proximal end and a distal end. The cannula is at least partially positioned in the handle lumen and extends beyond the handle distal end. The ablation apparatus is useful for ablation of soft palate tissue to eliminate snoring.

Abstract: A transurethral needle ablation device for the treatment of the prostate of a human male using radio frequency energy wall comprising a sheath having a lumen extending therethrough. A guide tube assembly is slidably mounted in the lumen in the sheath and having a lumen extending therethrough. A needle electrode is slidably mounted in the lumen in the guide tube assembly. An insulating sheath is disposed about the needle electrode so that the distal extremity of the needle electrode is exposed. A handle adapted to be gripped by the human hand is mounted on the proximal extremity of the sheath. Levers are carried by the handle for causing bending of the distal extremity of the guide tube assembly at an angle with respect to its longitudinal axis whereby the lumen in the guide tube assembly can be directed so that it faces the urethral wall. A control is carried by the handle and coupled to the needle electrode and the insulating sleeve for advancing and retracting the needle electrode with respect to the guide tube assembly whereby when the sheath is positioned in the urethra with its distal extremity in the vicinity of the prostate, the needle electrode can be advanced through the urethral wall and into the tissue of the prostate to permit the application of radio frequency energy to the tissue of the prostate surrounding the needle electrode to form a lesion in the prostate.

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.
