    • In general, the invention features an intra-vascular device for filtering or deflecting emboli or other large objects from entering a protected secondary vessel or vessels. The device of the invention may include a filter, an central member, additional supporting members, and a delivery cable and may serve to filter or deflect emboli or other large objects from entering protected secondary vessels. The device may be capable of collapse along its longitudinal axis for ease of delivery to the treatment site. The device may further be compatible with common delivery methods used in interventional cardiology (e.g., TAVI procedures). The device may be integrated into the delivery systems. In other embodiments the device may be detachable from the delivery system. Upon deployment, the device may be positioned so as to contact the orifice of one or more secondary blood vessels. Upon retrieval the device may be retracted in an orientation substantially similar to the original deployment orientation.
    • 通常,本发明的特征在于用于过滤或偏转栓塞或其他大物体进入受保护的次级血管或血管的血管内装置。 本发明的装置可以包括过滤器,中心构件,附加的支撑构件和输送电缆,并且可以用于过滤或偏转栓塞或其他大物体进入受保护的次级容器。 该装置可能能够沿其纵向轴线折叠以便于输送到治疗部位。 该装置还可以与介入心脏病学中使用的常规递送方法(例如,TAVI程序)兼容。 该装置可以集成到递送系统中。 在其他实施例中,装置可以从输送系统脱离。 在展开时,可以将装置定位成接触一个或多个次要血管的孔口。 在取回时,可以以基本上类似于原始展开方向的方向缩回装置。
