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 18):
A method for providing left-heart support using an intravascular blood pump system, the intravascular blood pump system comprising:\n an intravascular 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 intravascular blood pump comprising a rotor having a rotor hub tapering in a distal direction and a rotor shroud at least partially disposed about the rotor hub, at least one blade extending outward from the rotor hub, a distal end of the hub extending distally beyond a most distal portion of the at least one blade; a catheter coupled to a proximal end of the intravascular blood pump; a cannula coupled to a distal end of the intravascular blood pump, a 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 end of the rotor shroud, 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, the cannula is configured such that when the intravascular 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 lumen and the at least one first port are positioned in the patient's aorta, the intravascular blood pump is configured to draw blood from the patient's heart into the at least one second port through the cannula 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; and an elongate lumen sized to slidably receive the guide wire and dimensioned such that the guide wire passes slidably through the elongate lumen, the elongate lumen is sized smaller cross sectionally than the cannula lumen, both the elongate lumen and the cannula lumen not extending through the rotor hub, the elongate lumen adapted to guide the guide wire through a distal end of the intravascular blood pump system, the elongate lumen shorter in length than the cannula lumen; the method comprising the steps of:\n passing the guide wire through the patient's femoral artery such that a distal end of the guide wire is positioned in a left ventricle of the patient's heart; \n placing the guide wire through both the cannula and the elongate lumen, the guide wire not passing through the rotor hub or the catheter; \n advancing the cannula into the patient using the guide wire and positioning the cannula across the aortic valve of the patient such that a distal end of the cannula and the at least one second port are positioned in the left ventricle and a proximal end of the cannula and the at least one first port are positioned in an aorta, and the elongate lumen is wholly within the left ventricle during left-heart support; and \n spinning the rotor so as to pump 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.
