摘要： The invention provides a method and system for treatment of body strictures to restore luminal diameter to within a normal diameter range, in which the stricture is dilated to stretch its lumen to a desired diameter, collagen is exuded near to existing tissue of the stricture so as to be absorbed by that tissue or adhere to that tissue, making a collagen-enhanced tissue structure, and energy is emitted to affect the collagen-enhanced tissue, such as by ablation or by hardening. Ablation and hardening may be repeated so as to create a set of layers of hardened collagen in the form of a supporting frame, preferably having a hollow cylindrical shape. Dilation of the stricture is achieved by expanding one or more balloons, or by the pressure of exuded collagen, until the stricture is larger than a normal diameter range. When energy is emitted into the collagen, the stricture contracts back to the normal diameter range, either by ablation of excess tissue or by plating of the stricture wall. The stricture's tissue is also isolated by a set of balloons at either or both ends of the stricture, so as to isolate the stricture and restrict the collagen to the stricture's tissue. The stricture's tissue is also supported by a stent, which is preferably tackwelded onto the stricture's tissue using collagen. Collagen adheres to the stent, which supports the stricture's tissue until the stent is absorbed into that tissue.

摘要： Apparatus and methods are provided for treating female urinary incontinence by applying a form of energy to tissue in the vicinity of the urethra and/or bladder outlet to change tissue compliance without substantially narrowing the urethral and/or bladder outlet lumen. The apparatus comprises an elongated shaft having a means for treating urethral tissue and an expandable member deployable distal of the means for treating. The expandable member is configured to be anchored against the bladder outlet to dispose the means for treating at a desired treatment site in the urethra using only tactile feedback. The means for treating may include a needleless RF electrode, an ultrasound transducer, or a cryogenic probe configured to be advanced through a hollow needle, each of which are designed to reduce or eliminate symptoms associated with urinary incontinence.

摘要： Systems and methods introduce a closure material to seal a vessel puncture site. The system and methods provide a catheter adapted for passage through a tissue puncture and sized to occupy substantially all the tissue puncture. The catheter includes a lumen in fluid communication with a fluid delivery port adjacent the catheter distal end. One or more dispensers are in fluid communication with the catheter lumen for dispensing first and second fluid compositions in the catheter lumen. An actuator causes the first and second fluid compositions to be dispensed from the dispensers and mixed by flowing the first and second fluid compositions through a static mixer. The first and second fluid compositions are dispensed from the fluid delivery port as a fluid mixture that reacts in situ to form a nonfluent closure composition adjacent the vessel puncture site.

摘要： The invention provides a method and system for ablation of body structures or tissue in a sphincter, sinus or orifice such as the rectum, colon, esophagus, vagina, penis, larynx or pharynx. In one aspect of the invention, the environment surrounding the targeted ablation region can be isolated or controlled by blocking the flow of gases or liquids using an inflatable balloon positioned immediately adjacent to the tissue that is to be ablated. In a preferred embodiment, the inflatable balloon also serves to anchor the catheter in place and prevent the catheter from being expelled from the body. The inflatable balloon also insures that locally administered drug remain in the area where most needed. In a second aspect of the invention, positive pressure is used to inflate the balloon. Inflation of balloon triggers the extension of at least one curvilinear electrode into the targeted tissue. Negative pressure deflates the air sac and helps retract the curvilinear electrodes so as to allow the catheter to be removed from the body without damaging adjacent body structures. In a third aspect of the invention, the electrodes are coupled to sensors that measure properties of the target region such as temperature and impedance. Measurement of these properties permits the use of feedback technique to control delivery of the RF energy and administration of fluids for cooling and hydrating the affected tissues. In a fourth aspect of the invention, the catheter includes an optical path that can be coupled to external viewing apparatus. In this way, the position of the electrodes in the body can be determined by fluoroscopic or fiber optic techniques.

摘要： This is a method and an apparatus for the introduction of therapeutic compounds into tissue, particularly cardiac tissue. The apparatus includes a catheter having an elongated flexible body and a tissue infusion apparatus including a hollow infusion needle configured to secure the needle into the tissue when the needle is at least partially inserted into the tissue to help prevent inadvertent removal of the needle from the tissue. This permits the selected therapeutic compound to be delivered to a specific site. The catheter may also include a visualization assembly including a transducer at the distal end of the body.

摘要： A cell necrosis apparatus comprises an elongated delivery device including a lumen and an energy delivery device. The energy delivery device includes at least a first and a second RF electrode each with a tissue piercing distal portion. The first and second RF electrodes are positionable in the elongated delivery device in a compacted state and deployable from the elongated delivery device with curvature in a deployed state. The first and second RF electrodes exhibit a changing direction of travel when advanced from the elongated delivery device to a selected tissue site. At least one infusion port is coupled to one of the elongated delivery device, the energy delivery device, the first RF electrode or the second RF electrode.

摘要： 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 at a surface of a nasal concha, an expandable member positioned adjacent the catheter distal portion, an energy delivery device for delivering ablative energy positioned adjacent the catheter distal portion, and a lumen coupled to the catheter for delivering a medium into the expandable member to expand the expandable member.
