What is claimed is:

1. An implantable blood pump, comprising:

a housing;

at least one stator disposed within the housing;

a rotor disposed within the housing, the at least one stator being configured to rotate the rotor when current is applied to the stator; and

at least one at least partially piezoelectric element disposed within the housing.

2. The blood pump of Claim 1 , wherein the at least one at least partially piezoelectric element is one from the group consisting of a ceramic disk and a ceramic tube.

3. The blood pump of Claim 2, wherein the at least one at least partially piezoelectric element is in communication with a power source.

4. The blood pump of Claim 3, wherein the at least one at least partially piezoelectric element includes a plurality of piezoelectric zones separated by at least one non-piezoelectric zone.

5. The blood pump of Claim 4, wherein the power source is configured to selectively apply at least one from the group consisting of a voltage and current to each of the plurality of piezoelectric zones.

6. The blood pump of Claim 3, wherein the at least one at least partially piezoelectric element is configured to vibrate when the power source applies at least one from the group consisting of a voltage and current to the at least one at least partially piezoelectric element.

7. The blood pump of Claim 3, wherein the at least one piezoelectric ment generates a surface potential during operation of the blood pump.

8. The blood pump of Claim 7, wherein the at least one at least partially piezoelectric element includes a plurality of piezoelectric zones separated by at least one non-piezoelectric zone.

9. The blood pump of Claim 8, wherein the power source is configured to regulate the surface potential of the plurality of piezoelectric zones.

10. The blood pump of any one of Claims 1-9, wherein the at least one at least partially piezoelectric element is entirely piezoelectric.

11. The blood pump of Claim 1, wherein the at least one stator includes: a first stator disposed within the housing, the first stator being configured to rotate the rotor when a at least one from the group consisting of a voltage and current voltage is applied to the first stator, the rotor being positioned within the housing downstream from the first stator; and a second stator disposed within the housing downstream from the rotor, the second stator being configured to rotate the rotor when a voltage is applied to the second stator; and

wherein the at least one piezoelectric element includes:

a first at least partially piezoelectric disk, the first at least partially piezoelectric disk being disposed between the first stator and the rotor; and a second at least partially piezoelectric disk downstream disposed between the second stator and the rotor.

12. The blood pump of Claim 11, wherein the first at least partially piezoelectric disk and the second at least partially piezoelectric disk are in communication with a power source exterior to the housing.

13. The blood pump of Claims 11 or 12, wherein the first at least partially piezoelectric disk and the second at least partially piezoelectric disk are composed of a ceramic disk.

14. The blood pump of Claim 12, wherein the first at least partially piezoelectric disk and the second at least partially piezoelectric disk each include a plurality of piezoelectric zones separated by at least one non-piezoelectric zone.

15. The blood pump of Claim 14, wherein the power source is configured to selectively apply at least one from the group consisting of a voltage and current to each of the plurality of piezoelectric zones and wherein the first at least partially piezoelectric disk and the second at least partially piezoelectric disk are configured to vibrate when the at least one from the group consisting of voltage and current is applied.
