    Abstract: 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.

    Abstract: An apparatus is disclosed for attaching a counter pulsation device (CPD) to a blood vessel in a human or animal subject, the apparatus including: an interposition graft having a first end configured to be attached to the blood vessel, a second end, and an interior passage providing fluid connection between the first end and the second end; and a pump graft having first end attached to the second end of the interposition graft, a second end configured to be attached to the CPD, and an interior passage providing fluid connection between the first end and the second end In some embodiments, the interior passage of the interposition graft includes a rough surface configured to promote biological growth on the surface, and the interior passage of the pump graft includes a smooth surface configured to inhibit biological growth on the surface.

    Abstract: A blood pump assembly can include various components such as a housing and a sensor configured to detect one or more characteristics of the blood. In some embodiments, the sensor can be coupled to the housing and can include a sensor membrane configured to deflect in response to a change in a blood parameter (e.g., pressure). The blood pump assembly can include a shield that covers at least a portion of the sensor membrane so as to protect the sensor from damage when the blood pump assembly is inserted through an introducer and navigated through the patient's vasculature and/or when the blood pump assembly is inserted into the heart in a surgical procedure. One or more protective layers can be deposited over the sensor membrane to prevent the sensor membrane from being dissolved through interactions with the patient's blood.
