Abstract

Systems, assemblies, and related modules for connecting components of medical devices employ connector cables with electrical conductors and optical fibers. A connector assembly for coupling a battery module with a medical system including an implanted or worn medical device includes an input connector and an output connector. The input connector includes metal contact plates, has no moving parts, and is sealed to prevent water or dust ingression into the housing. The output connector includes metal pins to electrically couple to the metal plates of the input connector, a connector cable including electrical conductors coupled to the metal pins configured to transmit electrical power and an optical fiber configured to transmit data, and a latching mechanism disposed at an end of the output connector configured to physically attach the output connector to the housing. The cable body has a substantially flat cross-section.

Claims

1. A mechanical circulatory support system comprising:

an implantable blood pump;

an external controller configured to supply power to the implantable blood pump and including an external controller input connector;

a battery module comprising a housing and one or more battery cells disposed within the housing; and

a connector cable configured to removably couple the external controller input connector to the battery module, wherein the connector cable comprises electrical conductors configured to transfer power from the one or more battery cells to the external controller and an optical fiber to transfer data between the external controller and the battery module.

2. The mechanical circulatory support system of claim 1, wherein the electrical conductors and the optical fiber are arranged in a linear array within the connector cable so that the connector cable has an elongated rectangular cross section.

3. The mechanical circulatory support system of claim 2, wherein the electrical conductors include two redundant pairs of conductors arranged symmetrically on opposite sides of the optical fiber to enable coupling of the battery module to the external controller input connector in each of two opposite orientations.

4. The mechanical circulatory support system of claim 2, wherein the external controller input connector comprises metal contact plates, has no moving parts, and is sealed to prevent water or dust ingression into the external controller via the external controller input connector.

5. The mechanical circulatory support system of claim 4, wherein the connector cable comprises spring-loaded metal pins of a complementary shape and size to the metal contact plates of the external controller input connector so as to allow electrical connection between the battery module and the external controller, wherein the metal pins extend from a first end of the connector cable.

6. The mechanical circulatory support system of claim 2, wherein the housing is a first housing, the external controller comprises a second housing, and wherein the connector cable comprises a latching mechanism configured to physically attach the connector cable to the second housing.

7. The mechanical circulatory support system of claim 6, wherein the latching mechanism comprises two latching arms, wherein each of the latching arms comprises a dimple of a complementary shape and size to a respective recess on a surface of the second housing.

8. The mechanical circulatory support system of claim 6, wherein the latching mechanism comprises a first magnetic element configured to latch to a second magnetic element mounted to the second housing.

9. The mechanical circulatory support system of claim 8, wherein the first magnetic element is configured to unlatch from the second magnetic element upon application of a particular breakaway force.

10. The mechanical circulatory support system of claim 2, wherein the connector cable is fixedly connected within the housing and extends from the housing to a battery module output connector, wherein the battery module output connector is configured to be removably coupled with the external controller input connector.

11. The mechanical circulatory support system of claim 10, wherein the battery module comprises a spooling assembly on which the connector cable can be spooled and unspooled to vary a length by which the connector cable extends from the housing.

12. The mechanical circulatory support system of claim 2, wherein the battery module comprises a battery module output connector, and wherein the connector cable comprises a first connector at a first end configured to be removably coupled with the external controller input connector and a second connector at a second end configured to be removably coupled with the battery module output connector.

13. The mechanical circulatory support system of claim 2, wherein the battery module comprises a battery module input connector configured to receive electrical power from another battery module and/or a charging unit.

14. The mechanical circulatory support system of claim 1, wherein the connector cable has a substantially flat cross-section.
