Abstract
A cardiac assist device comprising: an implantable pump having a first and second end and adapted to be mounted within a blood vessel, wherein the pump further comprises an impeller that rotates about an axis parallel to the flow of blood through the pump and wherein the impeller lateral movement is restrained between the first and second end by bearings positioned at respective first and second ends; and wherein the pump is powered by a first implanted coil and a second external coil mounted on either side of a skin barrier of a patient, wherein the first and second coils are in electrical communication to relay power across the skin barrier.
Claims23
A cardiac assist device comprising:
- an implantable pump having first and second ends and adapted to be mounted within a blood vessel;
- the pump comprising an impeller that rotates about an axis parallel to the flow of blood through the pump;
- lateral movement of the impeller is restrained between the first and second ends by bearings positioned at first and second ends, respectively;
- a battery adapted to power the implantable pump;
- wherein when the battery is not powering the pump, the pump is powered by a first implantable coil and a second external coil mounted on either side of a skin barrier of a patient, wherein the first and second coils are in electrical communication to relay power across the skin barrier;
- and
- wherein a ceramic heat sink positioned in the centre of the first implanted coil.
