    • Device and method for heating tissue, the device having a catheter shaft for insertion into a patient's body, a chamber formed by a collapsible balloon mounted on the catheter shaft and filled with an electrically conductive fluid, two or more electrical contacts enclosed within the chamber, a power supply for applying an electrical potential to the contacts, and a two or more conductors for connecting each of the contacts to the power supply. The fluid is heated on the basis of I.sup.2 R losses by a radio frequency electric current flowing between the electrodes, and the fluid in turn heats the surrounding tissue by heat transfer through the wall of the chamber. According to the method, the apparatus is inserted into the patient's body, the chamber is filled with an electrically conductive fluid, and an electrical potential is applied to the contacts. The apparatus functions as a temperature source. A thermister sensor in the balloon or in contact with tissue responds to the heating effect to control the application of the current. Advantageously, by periodic sensing of temperature, and application of controlled rf power, a preset constant temperature is maintained at the selected sensing point, either at the internal body site or the liquid within the balloon. In this way carefully controlled therapy can be conducted at constant temperature.
    • 用于加热组织的装置和方法,所述装置具有用于插入患者体内的导管轴,由可安装在导管轴上并填充有导电流体的可折叠气囊形成的腔室,封闭在腔室内的两个或更多个电触点, 用于向触点施加电势的电源,以及用于将每个触点连接到电源的两个或更多个导体。 基于I2R损耗,通过在电极之间流动的射频电流来加热流体,并且流体又通过腔室壁的热传递来加热周围组织。 根据该方法,将该装置插入到患者体内,对该腔室填充有导电性流体,并向触点施加电位。 该装置用作温度源。 气囊中的热敏传感器或与组织接触的热敏电阻传感器响应加热效应以控制电流的施加。 有利地,通过周期性地检测温度和施加受控射频功率,在所选择的感测点处,在内部身体部位或球囊内的液体中保持预设的恒定温度。 以这种方式,可以在恒温下进行精心控制的治疗。

    • An implantable medical device and method for adjustably restricting a selected body lumen such as a urethra or ureter of a patient to treat urinary incontinence or ureteral reflux. The device includes an adjustable element and a tubular elongate body, where the adjustable element includes a chamber and the tubular elongate body includes at least a first interior passageway which extends longitudinally in the tubular elongate body from a first opening at the proximal end to a second opening in fluid communication with the chamber. Fluid volume passed through the first passageway is used for adjustably expanding or contracting the adjustable element. The implantable medical device further includes a sheath and a sleeve, where the sheath includes a wall having an inner surface which defines a channel through which at least a portion of the implantable device and the sleeve can pass. Alternatively, the implantable medical device includes a tip suitable to penetrate tissue so that the implantable medical device can be implanted within the tissue of a patient.
