Abstract
The present invention relates to a heart pump apparatus comprising a turbine pump for assisting the heart of a human patient. The invention is based on the realization that a turbine without a centre axis would improve the capacity of the heart help pump apparatus. The present invention also relates to a turbine pump system for assisting the heart of a human patient. The present invention also relates to operation methods and methods for surgically placing a rotating body of a turbine pump and a stator of a turbine pump in a patient.
Claims17
A heart pump apparatus for assisting the heart of a human patient, the heart pump apparatus comprising:
- a turbine pump adapted to be placed in a blood stream in the human patient to provide the heart of the human patient with additional pumping capacity,
- wherein said turbine pump is a centre axis free turbine pump, and
- said turbine pump comprises at least two rotating bodies that can be implanted in sequence in the same blood vessel, wherein one rotating body is adapted to rotate clockwise and the following other rotating body is adapted to rotate counter clockwise, or vice versa, and
- wherein said turbine pump defines a longitudinal centre and is adapted to accelerate a blood fluid flow in a direction parallel to said longitudinal centre,
- wherein each of the rotating bodies comprise blades extending internally from the respective rotating body.
