摘要： A device for sterilizing females by occluding the uterotubal junction. The device includes a catheter with a releasable heat generating plug which is used to thermally damage the uterotubal junction and cause it to constrict around the plug, after which the plug is released from the catheter and left in place in the uterotubal junction.

摘要： A catheter includes a plurality of primary leads to deliver energy for ligating a hollow anatomical structure. Each of the primary leads includes an electrode located at the working end of the catheter. Separation is maintained between the primary leads such that each primary lead can individually receive power of selected polarity. The primary leads are constructed to expand outwardly to place the electrodes into apposition with an anatomical structure. High frequency energy can be applied from the leads to create a heating effect in the surrounding tissue of the anatomical structure. The diameter of the hollow anatomical structure is reduced by the heating effect, and the electrodes of the primary leads are moved closer to one another. Where the hollow anatomical structure is a vein, energy is applied until the diameter of the vein is reduced to the point where the vein is occluded. In one embodiment, a secondary lead is surrounded by the primary leads, and extends beyond the primary leads. The secondary lead includes an electrode at the working end of the catheter. The secondary lead can have a polarity opposite to the polarity of the primary leads in a bipolar configuration. The polarity of the leads can be switched and the catheter can be moved during treatment to ligate an extended length of the vein. The catheter can include a lumen to accommodate a guide wire or to allow fluid delivery.
摘要翻译：导管包括多个主引线以传递用于结扎中空解剖结构的能量。每个主引线包括位于导管工作端的电极。在主引线之间保持分离，使得每个主引线可以分别接收所选极性的功率。主引线被构造成向外扩展以使电极与解剖结构相配合。可以从引线施加高频能量以在解剖结构的周围组织中产生加热效果。中空解剖结构的直径由于加热效应而降低，并且主引线的电极彼此靠近地移动。当中空解剖结构为静脉时，施加能量直到静脉的直径减小到静脉闭塞的位置。在一个实施例中，次级引线被主引线包围，并且延伸超出主引线。次级引线包括在导管的工作端的电极。次级引线可以具有与双极配置中的主引线的极性相反的极性。可以切换引线的极性，并且可以在治疗期间移动导管以连接延长的静脉长度。导管可以包括用于容纳导丝或者允许流体输送的内腔。
