摘要: Apparatus and methods are provided for thermally and/or mechanically treating tissue, such as valvular structures, to reconfigure or shrink the tissue in a controlled manner. The apparatus comprises a catheter in communication with an end effector which induces a temperature rise in an annulus of tissue surrounding the leaflets of a valve or in the chordae tendineae sufficient to cause shrinkage, thereby causing the valves to close more tightly. Mechanical clips can also be implanted over the valve either alone or after the thermal treatment. The clips are delivered by a catheter and may be configured to traverse directly over the valve itself or to lie partially over the periphery of the valve to prevent obstruction of the valve channel. The clips can be coated with drugs or a radiopaque coating. The catheter can also incorporate sensors or energy delivery devices, e.g., transducers, on its distal end.

摘要翻译: 提供了用于热和/或机械处理组织(例如瓣结构)的设备和方法,以受控的方式重新配置或收缩组织。 该装置包括与端部执行器连通的导管,该导管引起围绕瓣膜小叶或组合腱索中的组织的环空中的温度升高,足以导致收缩,从而导致瓣膜更紧密地闭合。 机械夹子也可以单独地或在热处理之后植入阀上。 夹子由导管递送,并且可以被配置成直接在阀本身上移动或部分地位于阀的周边上以防止阀通道的阻塞。 夹子可以涂上药物或不透射线的涂层。 导管还可以在其远端上并入传感器或能量输送装置,例如换能器。
