    摘要: An intravascular blood pump has an intake filter that reduces risk of heart tissue being sucked into an intake port of the pump. The filter defines a plurality of apertures, through which blood flows through the filter. The apertures are sized to prevent ingestion, by the input port, of the heart tissue. The filter includes a plurality of generally helical first struts wound about a longitudinal axis of the filter, and a plurality of second struts. The first and second struts collectively define the plurality of apertures therebetween. The struts may be woven filaments, or the apertures may be defined in a thin film (foil) tube, where remaining material between the apertures form the struts.

    摘要: A ventricular support system including a light source, a fiber optic splitter, two or more filters, an intravascular blood pump having two or more sensor heads, and a photodetector is disclosed. At least some of the light transmitted by the light source is split by the fiber optic splitter such that a portion is transmitted to each of the two or more filters. Each portion of light is filtered by one of the two or more filters and transmitted to one of the two or more sensor heads. Light beams reflected from each of the two or more sensor heads are combined by the fiber optic splitter. At least some of the combined light beams are received by the photodetector. By only using a single light source and a single photodetector with the two or more sensor heads, the ventricular support system may have improved portability.
