Abstract
The invention relates to an impeller (1) for an implantable, vascular support system (2), at least comprising: —an impeller body (3) having a first longitudinal portion (4) and a second longitudinal portion (5); —at least one blade (6) formed in the first longitudinal portion (4) and designed to axially convey a fluid by means of a rotational movement; —at least one magnet (7) provided and encapsulated in the second longitudinal portion (5).
Claims22
A method for producing an impeller for a cardiac support system, the method comprising:
- encapsulating at least one magnet in a second longitudinal portion of an impeller body of the impeller, wherein the impeller body further comprises a first longitudinal portion comprising at least one blade configured to axially convey a fluid by a rotational movement,
- wherein the second longitudinal portion comprises a first rotor extending axially configured to form a radial magnetic coupling with a second axially-extending rotor comprising at least one magnet, the radial magnetic coupling comprising an axial force between the first and second rotors.
An impeller for a cardiac support system, the impeller comprising:
- an impeller body comprising:
- a first longitudinal portion comprising at least one blade configured to axially convey a fluid by a rotational movement;
- and
- a second longitudinal portion comprising a magnet mount, the magnet mount comprising at least one recess that extends inward from an outer surface of the second longitudinal portion and configured to receive at least one magnet, wherein the second longitudinal portion is configured to:
- (1) position the at least one magnet when received by the magnet mount with an axial offset with respect to at least one magnet of a drive rotor of the cardiac assist system, and (2) form a radial magnetic coupling comprising an axial force with the at least one magnet of the drive rotor of the cardiac assist system when assembled.
