Abstract

An implantable blood pump system is disclosed herein. The implantable blood pump system includes an implantable blood pump and a controller coupled to the blood pump. The controller includes a partially sealed housing defining an internal volume. The controller includes an energy storage component contained within the internal volume and a processor. The processor can generate one or several signals affecting operation of the implantable blood pump. The controller includes a connector receptacle including a plurality of contacts selectively coupled via a circuitry to the energy storage component. The circuitry can electrically couple the plurality of contacts to the energy storage component when a connector insert is received within the connector receptacle and deactivate the plurality of contacts from the energy storage component when the connector insert is not within the connector receptacle.

First claim

What is claimed is:

1. An implantable blood pump system comprising:
an implantable blood pump; and
a controller coupled to the implantable blood pump, the controller comprising:
a partially sealed housing defining an internal volume;
an energy storage component contained within the internal volume;
a processor configured to generate one or several signals affecting operation of the implantable blood pump; and
a connector receptacle located in a portion of the housing and comprising a plurality of contacts selectively coupled via a circuitry to the energy storage component, wherein the circuitry is configured to electrically couple the plurality of contacts to the energy storage component when a connector insert is received within the connector receptacle and wherein the circuitry comprises a diode configured to deactivate at least one of the plurality of contacts from the energy storage component when a mating contact of the connector insert is not mated with the at least one of the plurality of contacts of the connector receptacle.

2. The system of claim 1 , wherein the partially sealed housing is water-tight and non-air-tight.

3. The system of claim 2 , wherein the partially sealed housing is configured to facilitate degassing of the energy storage component during a degassing failure mode when in use.

4. The system of claim 2 , wherein the connector insert is sealed.

5. The system of claim 1 , wherein the housing comprises multiple pieces joined and partially sealed together to define the internal volume.

6. The system of claim 5 , wherein the multiple pieces are joined and partially sealed by at least one of: a weld; a gasket; adhesive bonding; or solvent bonding.

7. The system of claim 1 , wherein the circuitry is configured to detect connection with the connector insert.

8. The system of claim 1 , wherein the controller further comprises at least one output protection module configured to protect the implantable blood pump from high output voltages.

9. The system of claim 1 , wherein the controller further comprises a management circuit configured to at least one of monitor the energy storage component, control output of the energy storage component, or maximize life of the energy storage component.

10. The system of claim 1 , wherein the energy storage component comprises a battery, wherein the battery comprises four cells arranged in a 2×2S configuration.

11. A controller of an implantable medical device, the controller comprising:
a housing defining an internal volume;
an energy storage component;
a processor configured to generate one or several signals affecting operation of the implantable medical device; and
a connector receptacle located in the housing and comprising a plurality of contacts selectively coupled via a circuitry to the energy storage component, wherein the circuitry is configured to deactivate the plurality of contacts from the energy storage component when mating contacts of a connector insert are not mated to the plurality of contacts of the connector receptacle, wherein the plurality of contacts comprises at least one positive contact and at least one negative contact, wherein the circuitry is configured to detect connection of the at least one negative contact with at least one corresponding mating contact of the connector insert, and wherein the circuitry is configured to deactivate the plurality of contacts when the at least one negative contact is not connected with the at least one corresponding mating contact of the connector insert.

12. The controller of claim 11 , wherein the housing is at least partially sealed.

13. The controller of claim 12 , wherein the partially sealed housing is water-tight and non-air-tight.

14. The controller of claim 13 , wherein the energy storage component comprises a battery.

15. The controller of claim 14 , wherein the battery comprises four cells arranged in a 2×2S configuration.

16. The system of claim 11 , wherein the circuitry selectively coupling the plurality of contacts to the energy storage component comprises a diode configured to deactivate at least one of the plurality of contacts when a mating contact of the connector insert is not mated with the at least one of the plurality of contacts.

17. An implantable blood pump system comprising:
an implantable blood pump; and
a controller coupled to the implantable blood pump, the controller comprising:
a partially sealed housing defining an internal volume;
an energy storage component contained within the internal volume, wherein the energy storage component comprises a battery tolerant of a single fault failure, wherein the battery comprises four cells arranged in two parallel battery packs in a 2×2S configuration;
a processor configured to generate one or several signals affecting operation of the implantable blood pump; and
a connector receptacle located in a portion of the housing and comprising a plurality of contacts selectively coupled via a circuitry to the energy storage component, wherein the circuitry is configured to electrically couple the plurality of contacts to the energy storage component when a connector insert is received within the connector receptacle and deactivate the plurality of contacts from the energy storage component when the connector insert is not within the connector receptacle.

18. The system of claim 17 , wherein the single fault failure comprises failure of one of the two parallel battery packs.

19. The controller of claim 17 , wherein the circuitry selectively coupling the plurality of contacts to the energy storage component comprises a diode configured to deactivate at least one of the plurality of contacts when a mating contact is not mated with the at least one of the plurality of contacts.

20. A controller of an implantable medical device, the controller comprising:
a housing defining an internal volume, wherein the housing is at least partially sealed and comprises multiple pieces joined and partially sealed together to define the internal volume, and wherein the multiple pieces are joined and partially sealed by at least one of: a weld; a gasket; an adhesive bond; or a solvent bond
an energy storage component;
a processor configured to generate one or several signals affecting operation of the implantable medical device; and
a connector receptacle located in the housing and comprising a plurality of contacts selectively coupled via a circuitry to the energy storage component, wherein the circuitry is configured to deactivate the plurality of contacts from the energy storage component when mating contacts of a connector insert are not mated to the plurality of contacts of the connector receptacle.
