摘要： The present invention is directed to methods and systems for adjusting an implant, such as a mitral valve ring, over the long term without having to enter a patient's body. The long term adjustment system can include a magnet, or other magnetic material, that is functionally connected to the adjustment mechanism of an adjustable implant. The long term adjustment system can be activated by placing an activating magnet near the area of the patient's body where the adjustable implant is located and positioning the activating magnet so that an attractive force is generated between the activating magnet and the magnet that is functionally connected to the adjustable implant. Due to the attractive force between the two magnets, rotation of the magnet outside the patient's body will adjust the size and/or shape of the implant.
摘要翻译：本发明涉及用于长期调整诸如二尖瓣环的植入物的方法和系统，而不必进入患者体内。长期调节系统可以包括功能上连接到可调节植入物的调节机构的磁体或其他磁性材料。可以通过将激活磁体放置在患者身体的可调节植入物所在的区域附近并定位激活磁体来激活长期调节系统，使得在激活磁体和磁体之间产生吸引力，功能上连接到可调植入物。由于两个磁体之间的吸引力，磁体在患者身体外部的旋转将调整植入物的尺寸和/或形状。

摘要： An evacuation sheath assembly and method of treating occluded vessels which reduces the risk of distal embolization during vascular interventions is provided. The evacuation sheath assembly includes an elongated tube defining an evacuation lumen having proximal and distal ends. A proximal sealing surface is provided on a proximal portion of the tube and is configured to form a seal with a lumen of a guided catheter. A distal sealing surface is provided on a distal portion of the tube and is configured to form a seal with a blood vessel. A method of treatment of a blood vessel using the evacuation sheath assembly includes advancing the evacuation sheath assembly into the blood vessel through a guide catheter. Prior to advancing a device across a stenosis to be treated, normal antegrade blood flow in the blood vessel proximate to the stenosis is stopped. While blood flow is stopped, the stenosis is treated. Retrograde blood flow is induced within the blood vessel to carry embolic material dislodged during treating into the evacuation sheath assembly.
摘要翻译：提供疏散鞘组件和治疗闭塞血管的方法，其减少血管干预期间远端栓塞的风险。抽真空组件包括限定具有近端和远端的抽空腔的细长管。近侧密封表面设置在管的近端部分上，并被构造成与引导导管的内腔形成密封。远端密封表面设置在管的远端部分上并构造成与血管形成密封。使用排气鞘组件治疗血管的方法包括通过引导导管将排空鞘组件推进到血管中。在将装置推进通过待治疗的狭窄之前，停止在狭窄附近的血管中的正常顺行血流。当血流停止时，狭窄处理。在血管内引起逆行血流，以便在处理进入抽真空鞘组件期间将栓塞物移走。
