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.

Abstract: A percutaneous circulatory support device including a percutaneous blood pump coupled to a distal end region of an elongate shaft at a junction. The percutaneous blood pump is configured to pump blood through a housing of the percutaneous blood pump during use. The junction includes an end cap at a proximal end of the percutaneous blood pump surrounding and secured to a distal end region of the elongate shaft at the junction. The junction may include a fillet of material surrounding a proximal end region of the end cap and extending proximally thereof and surrounding an exterior surface of the elongate shaft. The proximal end region of the end cap may include an annular side wall with one or more apertures and/or one or more grooves extending into the annular side wall in which the fillet of material extends into.

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. A collar is coupled to the catheter and disposed proximally relative to the housing. The collar includes an internal chamber, and pressure sensor is disposed within the internal chamber of the collar.
