    • 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.
    • 本发明提供了用于收缩胶原组织的改进的装置,方法和系统,特别是通过将能量引导到患者自己的支撑组织以非侵入性方式治疗尿失禁。 这种能量加热筋膜和其他胶原支持组织,导致它们收缩。 间歇地施加能量,通常在具有冷却的平坦电极表面的一对大平板电极之间,电极可选地由夹持结构支撑。 这种冷却的平板电极能够将电能引导通过中间组织并进入筋膜,同时冷却的电极表面防止对中间组织的损伤,特别是在电极表面在间歇加热循环之前,期间和之后冷却。 理想地,平板电极包括包括分立电极表面段的电极阵列,使得可以改变电流通量以选择性地靶向仪表板。 或者,冷却的“液体电极”可以引导电流通过膀胱(或其他体腔)的选定部分,同时还冷却膀胱壁,绝缘气体可以防止替代膀胱部分和相邻组织和/或超声波的加热 换能器将能量通过中间组织直接导入筋膜,对中间组织几乎没有或没有损伤。 冷却的电极可用于冷却中间接合组织,以便在开始RF加热之前引起目标组织和中间组织之间的最大温差。 这允许控制和/或最小化达到治疗温度的组织的尺寸,被保护的中间组织的尺寸被最大化等等。
