    摘要： 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.

    摘要： An intravascular blood pump includes a pump housing having an input port and an output port. A relatively short intake cannula may draw blood in through an intake port and deliver the blood to the input port of the pump housing. The intake cannula is relatively short, to prevent excess hydraulic loss. An outflow hose is connected to the output port of the pump housing, so as to convey blood exiting the output port through the outflow hose in a downstream direction to a discharge port, e.g. into an aorta or other blood vessel. Despite the short intake cannula, the outflow hose longitudinally separates the intake port from the discharge port sufficiently so the intake port and the discharge port remain on opposite sides of a heart valve, despite inadvertent longitudinal shifts of the intravascular heart pump.
