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.

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: Drive components and rotor housings for use in intravascular blood pumps, such as blood pumps configured to make the pump section more resistant to bending, kinking, and/or plastic deformation in combination with a catheter that controls a position of the intravascular blood pump to mitigate suction events that may occur due to the pump section's proximity to a patient's vasculature.
