Implantable heart pump controller
The present invention provides devices, systems, and methods for control of and communication with ventricular assist devices. In certain embodiments, the invention includes an implantable controller that is operatively programmed to direct physiological flow through a ventricular assist device that can be substantially synchronized to the cardiac cycle of the subject. In certain embodiments, the implantable controller is also communicatively connected to an external control unit, such that the implantable controller can transmit data to the external control unit, and instructions can be sent from the external control unit to the implantable controller. In certain embodiments, a system and method for secure communication between a remote device and the implanted ventricular assist device is provided.
1. A system for remote communication with an implantable ventricular assist device comprising:
the implantable ventricular assist device configured to authenticate a communication session between the implantable ventricular assist device and a mobile device using a first key-id stored on the implantable ventricular assist device; and
a software platform configured to verify a second key-id to authenticate a communication session between the mobile device and the software platform, the software platform further configured to verify a patient specific key received from a remote device to authenticate a communication session between the software platform and a remote device;
wherein the software platform is configured to establish a communication session to send values from the remote device to the implantable ventricular assist device based on verifying all of the first key-id, the second key-id and the patient specific key.
2. The system of claim 1 , wherein the patient specific key is based on the first key-id.
3. The system of claim 1 , wherein the software platform is configured to generate the second key-id after detecting an initialization of a connection between the mobile device and the software platform.
4. The system of claim 1 , wherein the software platform is a server.
5. The system of claim 1 , wherein the remote device is a user computer.
6. The system of claim 1 , wherein the remote device is configured to accept input of the values through a web-based portal.
7. The system of claim 6 , wherein the values include at least one of systole power and diastole power.
8. The system of claim 6 , wherein the values include all of systole power, diastole power and the patient specific key.
9. The system of claim 1 , wherein the implantable ventricular assist device is configured to send feedback to the remote device after verifying all of the first key-id, the second key-id and the patient specific key.
10. The system of claim 9 , wherein the feedback includes at least one of a heart rate and a pump speed.
11. A method for remote communication with an implantable ventricular assist device comprising:
verifying a first key-id stored on the implantable ventricular assist device to authenticate a communication session between the implantable ventricular assist device and a mobile device;
verifying a second key-id to authenticate a communication session between the mobile device and a software platform; and
verifying a patient specific key to authenticate a communication session between the software platform and a remote device;
wherein a communication session to send values from the remote device to the implantable ventricular assist device is authenticated based on verifying all of the first key-id, the second key-id and the patient specific key.
12. The method of claim 11 , wherein the patient specific key is based on the first key-id.
13. The method of claim 11 , wherein the second key-id is generated at initialization of connection between the mobile device and the software platform.
14. The method of claim 11 , wherein the software platform is a server.
15. The method of claim 11 , wherein the remote device is a user computer.
16. The method of claim 11 further comprising:
accepting input of the values through a web-based portal.
17. The method of claim 16 , wherein the values include at least one of systole power and diastole power.
18. The method of claim 17 , wherein the values include all of systole power, diastole power and the patient specific key.
19. The method of claim 11 further comprising:
sending feedback from the implantable ventricular assist device to the remote device after verifying all of the first key-id, the second key-id and the patient specific key.
20. The method of claim 19 , wherein the feedback includes at least one of a heart rate and a pump speed.
