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 25):
An 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 rotor 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 first 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 lumen of the cannula and an exterior region of the cannula, wherein at least one first port is located in proximity to the rotor and at least one second port 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, wherein the guide wire does not pass through the rotor hub or the catheter; a pigtail shaped distal tip or a J-shaped distal tip, wherein when the intravascular blood pump is positioned in the patient to provide left-heart support the pigtail shaped distal tip or the J-shaped distal tip are wholly within a left ventricle of the patient; and a pressure sensing element configured to sense pressure proximate the intravascular blood pump comprising a fluid column extending through the catheter.
