Abstract:
An improved intravascular blood pump and related methods involving the broad inventive concept of equipping the intravascular blood pump with guiding features such that the intravascular blood pump can be selectively positioned at a predetermined location within the circulatory system of a patient.

Claim (Index 2):
An intravascular blood pump system, comprising:\n a blood pump adapted to be guided to a predetermined location within a circulatory system of a patient by a guide wire and configured to provide left-heart support, the blood pump comprising a rotor having a rotor hub and at least one blade extending outward from the rotor hub; a rotor shroud at least partially disposed about the rotor hub; an elongate catheter extending proximally with respect to the blood pump; a cannula extending from the rotor shroud and comprising an outer cannula surface, the outer cannula surface having a substantially circular cross-section along a portion of its length, wherein a distal portion of the rotor shroud having an outer diameter matching an inner diameter of a proximal portion of the cannula, the proximal portion of the cannula disposed about a distal portion of the rotor shroud, and wherein at least a proximal portion of the rotor shroud has the same outer diameter as the proximal portion of the cannula; one or more first ports and one or more second ports establishing fluid communication between a cannula lumen and an exterior region of the cannula, wherein at least one first port of the one or more first ports is located in proximity to the rotor and at least one second port of the one or more second ports is spaced apart from and located distal to the at least one first port, wherein the cannula is configured such that when the blood pump is positioned in the patient to provide left-heart support a distal end of the cannula and the at least one second port are positioned inside the patient's heart and a proximal end of the cannula and the at least one first port are positioned in the patient's aorta, and the blood pump is configured to draw blood from the patient's heart into the at least one second port through the cannula lumen and out the at least one first port to provide left-heart support while the cannula is positioned across an aortic valve of the patient; a pigtail shaped distal tip or a J-shaped distal tip, wherein a proximal end of the pigtail shaped distal tip or the J-shaped distal tip is fixed or attached to a distal end of the cannula and the pigtail shaped distal tip or the J-shaped distal tip is distal to each of the one or more second ports; and a pressure sensing element configured to sense pressure proximate the blood pump comprising a fluid column extending through a catheter.
