    摘要: Apparatus and methods for uniformly distributing coolant within a cryo-ablation device. A nozzle apparatus includes a tubular member having a plurality of angled apertures that induce swirling of coolant streams dispersed through the angled apertures. Coolant swirling round the tubular member and along an inner surface of an inflatable balloon element inflates the balloon element and cryogenically ablate tissue. The swirling action achieved using angled apertures uniformly distributes coolant along the inner surface of the balloon such that the temperatures along an inner surface of the balloon element and ablation of tissue adjacent to the balloon element are substantially uniform.

    摘要: Apparatuses and methods facilitate delivery of optical or photoacoustic energy to innervated vascular that contributes to renal sympathetic nerve activity. The optical energy delivered may be of sufficient power to scan or image innervated renal or aortal tissue. The optical energy delivered may be of sufficient power to ablate innervated renal or aortal tissue, such as by thermal laser ablation or photoacoustic laser ablation. A catheter for intravascular or extravascular deployment supports an optical fiber arrangement comprising a coupling for receiving light from a laser light source. An optics arrangement is supported by the catheter and coupled to the optical fiber arrangement. The optics arrangement includes one or more optical elements arranged to receive the laser light and direct optical energy to target innervated tissue or a water source from which a cavitation bubble may be created and launched for acoustically shocking the target innervated tissue.

    摘要: A method, system, and device for detecting whether an expandable member completely occludes an anatomic passageway allows a user, such as a physician, clinician, or surgeon, to perform a medical procedure more efficiently and increases the procedure's chances of success. An incomplete occlusion can be immediately detected by monitoring the pressure difference across the expandable member. Through this method, a user can quickly diagnose the problem and reposition the expandable member in the anatomic passageway. In particular, in a cryoablation procedure, devices incorporating this method can help ensure a uniform and complete lesion in the pulmonary vein to electrically isolate the pulmonary vein from the atrium, thus preventing atrial fibrillation.

    摘要: The invention provides improved devices, methods, and systems for shrinking of collagenated tissues, particularly for treating urinary incontinence in a noninvasive manner by directing energy to a patient's own support tissues. This energy heats fascia and other collagenated support tissues, causing them to contract. The energy can be applied intermittently, often between a pair of large plate electrodes having cooled flat electrode surfaces, the electrodes optionally being supported by a clamp structure. Such cooled plate electrodes are capable of directing electrical energy through an intermediate tissue and into fascia while the cooled electrode surface prevents injury to the intermediate tissue, particularly where the electrode surfaces are cooled before, during, and after an intermittent heating cycle. Ideally, the plate electrode comprises an electrode array including discrete electrode surface segments so that the current flux can be varied to selectively target the fascia. Alternatively, chilled “liquid electrodes” may direct current through a selected portion of the bladder (or other body cavity) while also cooling the bladder wall, an insulating gas can prevent heating of an alternative bladder portion and the adjacent tissues, and/or ultrasound transducers direct energy through an intermediate tissue and into fascia with little or no injury to the intermediate tissue. Cooled electrodes may be used to chill an intermediate engaged tissue so as to cause the maximum temperature difference between the target tissue and the intermediate tissue prior to initiating RF heating. This allows the dimensions of tissue reaching the treatment temperature to be controlled and/or minimized, the dimensions of protected intermediate tissue to be maximized, and the like.
