Abstract
An improved intravascular blood pump system (10) and related methods involving the broad inventive concept of equipping the intravascular blood pump (12) with guiding features such that the intravascular blood pump can be selectively positioned at a predetermined location within the circulatory system of a patient.
Claims20
An intravascular blood pump system comprising:
- an intravascular blood pump having a cannula coupled thereto, said intravascular blood pump including a rotor, a shroud for receiving said rotor, and a drive cable coupled to said rotor for driving said rotor within said shroud, said cannula being coupled to said shroud of said intravascular blood pump, and
- a guide mechanism adapted to guide said intravascular blood pump and cannula to a predetermined location within the circulatory system of a patient, wherein said guide mechanism comprises a guide catheter coupled to said shroud.
An intravascular blood pump system comprising:
- an intravascular blood pump having a cannula coupled thereto, said intravascular blood pump including a rotor, a shroud for receiving said rotor, and a drive cable coupled to said rotor for driving said rotor within said shroud, and
- a guide mechanism adapted to guide said intravascular blood pump and cannula to a predetermined location within the circulatory system of a patient,
- wherein a drive cable sheath is provided having a central lumen for receiving said drive cable, and
- wherein a purge fluid delivery system is coupled to said drive cable sheath to deliver purge fluid to said rotor.

An intravascular blood pump system comprising:
- an intravascular blood pump having a cannula coupled thereto,
- a guide mechanism adapted to guide said intravascular blood pump and cannula to a predetermined location within the circulatory system of a patient, and
- a blood pressure detection mechanism to detect the pressure of the blood proximate at least one of the intravascular blood pump and cannula.
An intravascular blood pump system comprising:
- an intravascular blood pump having a cannula coupled thereto, said intravascular blood pump including a rotor, a shroud for receiving said rotor, and a drive cable coupled to said rotor for driving said rotor within said shroud, and
- a guide mechanism adapted to guide said intravascular blood pump and cannula to a predetermined location within the circulatory system of a patient,
- said guide element comprising a guide wire for passage through a lumen extending through said drive cable and rotor.
