    • The emboli protection system provides one or more inflatable blocking balloons for isolation of a section of a blood vessel to prevent migration of emboli from the section during an interventional procedure, and fluid infusion and evacuation ports for flushing emboli from the isolated section. One embodiment provides for a distal blocking balloon catheter, over which an interventional device can be introduced, and a proximal blocking balloon catheter to be introduced over the interventional device for isolating a portion of a blood vessel to be treated. The blocking balloons can be perforated to provide the infusion ports, and thrombolytic inflation fluid may be used to break down and dissolve thrombus and plaque in the isolated portion of the blood vessel. The interventional therapeutic device such as an angioplasty balloon catheter may be incorporated into the distal blocking balloon catheter, or the distal and blocking proximal balloon catheters can be incorporated with the interventional therapeutic device together in one device. Infusion ports may also be provided in either or both of the distal and proximal blocking catheters.
    • 栓塞保护系统提供一个或多个可膨胀的阻塞气球,用于隔离血管的一部分,以防止在介入手术过程中栓塞从该部分移位,以及用于从隔离部分冲洗栓塞的流体输注和排出口。 一个实施例提供远端阻塞气囊导管,介入装置可以在其上引入,以及近端阻塞气囊导管,其被引入到介入装置上,用于隔离待治疗血管的一部分。 阻塞气囊可以被穿孔以提供输注口,并且可以使用溶栓膨胀流体来分解和溶解血管的孤立部分中的血栓和斑块。 诸如血管成形术气囊导管的介入治疗装置可以并入到远端阻塞气囊导管中,或者远端和阻塞近端球囊导管可以与介入治疗装置并入一个装置中。 输液口也可以设置在远端和近端阻塞导管中的一个或两者中。
