    • A system for providing access to at least one heart chamber for delivering and/or removing a fluid includes a selectively occludable conduit defining a lumen for providing access to an interior of at least one heart chamber from an exterior of a chest wall of the patient, and a dual lumen cannula adapted for passing through an interior lumen of the conduit. The selectively occludable conduit includes at least one balloon closure for substantially sealing an end of the conduit in fluid communication with the chamber of the heart. The dual lumen cannula includes a first, drainage lumen having at least one aperture for removing a fluid from the interior of the heart chamber, and a second, delivery lumen for delivering a fluid into the interior of the heart chamber. The delivery lumen may include an extendable infusion sleeve for delivering a fluid into an interior of the heart.
    • 用于提供进入至少一个心室的输送和/或去除流体的系统包括限定内腔的选择性可闭塞导管,用于从患者胸壁的外部提供进入至少一个心室的内部, 以及适于穿过导管的内腔的双腔插管。 选择性可闭塞管道包括至少一个气囊盖,用于基本上密封导管的与心脏腔室流体连通的端部。 双腔套管包括具有至少一个用于从心脏腔室内部移除流体的孔的第一排液腔和用于将流体输送到心室的内部的第二输送腔。 输送腔可以包括用于将流体输送到心脏内部的可伸展输液套筒。

    • An apparatus, system, and method for assisting a heart in circulating blood that has been damaged, for example, by a myocardial infarction. In at least one aspect, an apparatus, system, and method are used for inserting a single cannula assembly comprising at least an inner and outer cannula into the left ventricle, advancing the inner cannula portion of the cannula assembly past the aortic valve, and into the aorta without requiring a secondary cannula insertion through an external portion of the aorta. In another aspect, an intraventricular assistant device (IVAD) having a motor and impeller can be inserted directly into the heart, such as in the left ventricle. The IVAD uniquely provides a pump within the heart through a single insertion that can reduce thrombosis and lessen the complexities typically associated with such efforts.
    • 一种用于辅助心脏循环​​血液的装置,系统和方法,所述血液已被例如心肌梗死所损伤。 在至少一个方面,一种装置,系统和方法用于将包括至少内套管和外插管的单个插管组件插入左心室,使插管组件的内套管部分经过主动脉瓣,并且进入 主动脉,而不需要通过主动脉的外部部分插入第二插管。 另一方面,具有马达和叶轮的心室内辅助装置(IVAD)可以直接插入心脏,例如左心室。 IVAD通过单个插入独特地在心脏内提供泵,可以减少血栓形成并减少通常与此类作用相关的复杂性。
