Abstract: A method of treating a sphincter provides a catheter means and an energy delivery device means coupled to the catheter means. The energy delivery device means has a tissue piercing distal end. The catheter means is introduced into an esophagus. A sphincter exterior surface is pierced with the energy delivery device means tissue piercing distal. The energy delivery device means tissue piercing distal end is advanced a sufficient distance in an interior of the sphincter to a tissue site. Energy is controllably delivered to the tissue site. Controlled cell necrosis is created in the sphincter to reduce a frequency of sphincter relaxation.

Abstract: An apparatus to treat a uterus includes a deployable member configured to be positioned in a uterine cavity in at least a partially deployed state to define a microwave chamber in an interior of the deployable member, and removed from the uterine cavity in a non-deployed state. The deployable member is at least partially microwave energy absorbable and formed of a fluid permeable material to house and controllably release a fluidic medium from the microwave chamber when the deployable member is positioned in the uterine cavity in the at least partially deployed state. A microwave emitter is positioned in the microwave chamber, the microwave emitter is configured to be coupled to a microwave energy source and deliver microwave energy to the fluidic medium, wherein the fluidic medium transfers thermal energy from the microwave emitter to a uterine structure.

Abstract: A medical probe device comprises a catheter having a stylet guide housing with one or more stylet ports in a side wall thereof and a stylet guide for directing a flexible stylet outward through the stylet port and through intervening tissue at a preselected, adjustable angle to a target tissue. The total 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 radiofrequency electrode. Preferably, the non-conductive layer is a sleeve which is axially moveable on the electrical conductor to expose a selected portion of the electrical conductor surface in the target tissue. The stylet can also be a microwave antenna. The stylet can also be a hollow tube for delivering treatment fluid to the target tissue. It can also include a fiber optic cable for laser treatment. The catheter can include one or more inflatable balloons located adjacent to the stylet port for anchoring the catheter or dilation. Ultrasound transponders and temperature sensors can be attached to the probe end and/or stylet. The stylet guide can define a stylet path from an axial orientation in the catheter through a curved portion to a lateral orientation at the stylet port.

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.
