Abstract: A catheter assembly for use in a percutaneous heart pump includes a cannula housing defining an interior space, an impeller disposed within the interior space defined by the cannula housing, and a flexible atraumatic tip positioned distal of the cannula housing. A guidewire is coupled to the flexible atraumatic tip and extends proximally from the flexible atraumatic tip. The guidewire extends at least partly along an exterior of the cannula housing or at least partly within the interior space defined by the cannula housing between the impeller and the cannula housing.
