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.

Claims

1. An improved intravascular blood pump system, comprising:

an intravascular blood pump having a cannula coupled thereto; and

a guide mechanism adapted to guide said intravascular blood pump and cannula to a predetermined location within the circulatory system of a patient.
