SELECTIVE ACCUMULATION OF ENERGY WITHOUT KNOWLEDGE OF TISSUE TOPOGRAPHY

机译:无需组织地形知识的选择性积累能量

摘要

Medical devices and methods for making and using medical devices are disclosed. An example method may include a method for heating a body tissue region adjacent to a body lumen. The method may include positioning an energy delivery portion of a catheter within the lumen and engaging the body lumen with the energy delivery portion. Engaging the body lumen may complete a plurality of circuits. The method may also include determining a pulse characteristic in response to a thermal property of a first tissue type and applying controlled pulsed electrical energy with the pulse characteristic from the energy delivery portion through the plurality of circuits.
