Abstract
A percutaneous circulatory support device includes a housing and an impeller disposed within the housing. The impeller is configured to rotate relative to the housing to cause blood to flow through the housing. A motor is operably coupled to the impeller, and the motor is configured to rotate the impeller relative to the housing. A catheter is coupled to the motor, and a pressure sensor is coupled to the catheter and disposed proximally relative to the housing.
Claims20
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 sensor housing coupled to the catheter and disposed proximally relative to the motor, the sensor housing having a wall defining an internal chamber;
- a pressure sensor disposed within the internal chamber;
- and
- a sensor mount positioned within the internal chamber, the sensor mount supporting the pressure sensor such that the pressure sensor is spaced apart from the wall of the sensor housing.

- 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 sensor housing coupled to the catheter and disposed proximally relative to the motor, the sensor housing having a wall defining an internal chamber and a transversely-facing aperture extending through the wall;
- a pressure sensor disposed within the internal chamber such that the wall is spaced radially outward of the pressure sensor.
