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.
Claims11
An intravascular blood pump system, comprising:
- an intravascular blood pump having a cannula releasably coupled thereto, said intravascular blood pump including a rotor, a shroud for receiving said rotor, a biasing member biasing said rotor towards a docking position in which said rotor is received in said shroud, and a drive cable securedly coupled to said rotor for driving said rotor within said shroud;
- wherein said system comprises a pump assembly separable from a conduit assembly, said conduit assembly comprising said cannula and said, shroud, and said pump assembly comprising said rotor, said biasing member and said drive cable;
- and
- a central lumen extending through said shroud and said cannula for receiving a guide mechanism therethrough.
1 more element
An intravascular blood pump system, comprising:
- a pump assembly provided independent of and separable from a conduit assembly;
- said conduit assembly comprising a cannula coupled to a shroud;
- said pump assembly comprising a rotor and a drive cable coupled to said rotor and configured to drive said rotor;
- and
- wherein said pump assembly is dockable with said conduit assembly such that said rotor is receivable within said shroud and removable from said shroud by releasable docking thereof.
2 more elements
A method of installing a blood pump assembly within a location in a patient, said method comprising:
- positioning a conduit assembly within the patient, such that a shroud connected to a cannula of said conduit assembly is positioned in a desired location and wherein a pump assembly is not connected to said conduit assembly during said positioning;
- introducing a pump assembly into the patient and advancing the pump assembly to the position of the conduit assembly;
- and
- docking the pump assembly with the conduit assembly such that a rotor of the pump assembly is received within the shroud.
