1. A percutaneous circulatory support device, comprising:
a housing comprising an inlet and an outlet;
an impeller disposed within the housing, the impeller configured to rotate relative to the housing to cause blood to flow into the inlet, through the housing, and out of the outlet;
a motor operably coupled to the impeller, the motor configured to rotate the impeller relative to the housing;
a catheter coupled to the motor;
a pressure sensor coupled to the catheter and disposed proximally relative to the motor; and
a sensor housing comprising a wall covering a radially outward surface of the pressure sensor, the wall defining an internal chamber with a distally-facing aperture, the pressure sensor being disposed within the internal chamber.
