Abstract
An activating system is provided for a heart valve having a seat (1) and at least one pivoting flap (2a, 2b) mounted on the seat (1). The activating system includes at least one mobile magnetic element (4) connected with said flap (2a, 2b) and at least one fixed magnetic element (3) on the seat (1), with the magnetic elements (3, 4) producing interacting fields that create a force which is exerted on said flap (2a, 2b) during its opening and/or closing movements.
Claims23
An activated heart valve, comprising:
- a heart valve which comprises
- a seat, and
- at least one flap pivotally mounted on said seat;
- and
- an activating system which comprises
- at least one respective mobile magnetic element connected with each said at least one flap, and
- at least one fixed magnetic element mounted to said seat, said fixed and said mobile magnetic elements producing magnetic fields that interact to generate a force which urges said at least one flap towards an equilibrium position when blood pressure is identical on either side of said valve, wherein said equilibrium position corresponds to a fixed table intermediate open position between a fully open position and a fully closed position of said at least one flap.
