蒸汽消融系统
Abstract:
提供了一种蒸汽输送系统，包括细长的轴，其构造成被插入至患者的尿道中；蒸汽输送针，其包括多个蒸汽输送口，且布置在轴中并构造成当该轴就位在患者的尿道中时从该轴大致横向地推进到前列腺中；蒸汽发生器，其联接至蒸汽输送针，以通过蒸汽输送针的蒸汽输送口使得凝结的液体离开蒸汽输送针的蒸汽输送口；和操作性地联接至蒸汽发生器的电子控制器，其构造成：将第一剂量的蒸汽从蒸汽发生器经蒸汽输送针的蒸汽输送口输送到前列腺中；将第二剂量的蒸汽从蒸汽发生器经蒸汽输送针的蒸汽输送口输送到前列腺中；和在第一剂量的蒸汽和第二剂量的蒸汽的输送之间，经蒸汽输送针泵送连续的蒸汽流，以防止在蒸汽输送系统中形成凝结。
Abstract(English):

A vapor delivery system and method is provided that includes a number of features. In one embodiment, a method comprises inserting a vapor delivery needle into tissue of a patient, activating a flow of vapor from a vapor generator through vapor delivery ports of the vapor delivery needle to cause condensed liquid to exit vapor delivery ports of the vapor delivery needle, generating vapor in the vapor generator, delivering a dose of vapor through the vapor delivery ports of the vapor delivery needle into the tissue, and after the dose of vapor is delivered, re-activating the flow of vapor from the vapor generator through the vapor delivery ports of the vapor delivery needle to prevent a vacuum from forming in the vapor delivery needle. Vapor therapy systems are also provided.
