Abstract

A control circuit for monitoring operation of an implantable blood pump, the control circuit operatively couplable to a testing apparatus for simulating blood pump operating conditions and testing the control circuit based on the simulated blood pump operating conditions. The control circuit includes an input module for receiving at least one of one of actual operating data from an implantable blood pump and simulated operating data from the testing apparatus. A processor for processing the received operating data is included, the processor configured to determine a source of the received operating data, and to determine whether the received operating data is actual operating data or simulated operating data based on the determined source.

Claims

1. A control circuit for monitoring operation of an implantable blood pump, the control circuit operatively couplable to a discrete testing apparatus configured to simulate blood pump operating conditions and testing the control circuit based on the simulated blood pump operating conditions, the control circuit comprising:

an input module for receiving at least one from the group consisting of actual operating data from the implantable blood pump and simulated operating data from the testing apparatus;

a processor for processing the received operating data, the processor configured to determine a source of the received operating data, and to determine whether the received operating data is one from the group consisting actual operating data from the implantable blood pump and simulated operating data based on the determined source.

2. The control circuit of claim 1, wherein the processor is communicatively couplable to a data store and further configured to log, in the data store, the received operating data and an indication of whether the received operating data is simulated operating data.

3. The control circuit of claim 1, wherein the processor is configured to log the actual operating data in a data log, and to omit the simulated operating data from the data log containing the actual operating data.

4. The control circuit of claim 1, wherein the processor is further configured to detect an adverse physiological event based on the received operating data, to provide an alert in response to detection of the adverse physiological event, and to override providing the alert in response to determining that the received operating data is simulated operating data.

5. The control circuit of claim 4, wherein the adverse physiological event is at least one from the group consisting of a ventricular suction condition, a high blood pressure condition, an arrhythmia, thrombosis, and a stroke.

6. The control circuit of claim 1, wherein the processor is further configured to detect an operational pump error based on the received operating data, to provide an alert in response to detection of the operational pump error, and to override providing the alert in response to determining that the received operating data is simulated operating data.

7. The control circuit of claim 6, wherein the operational pump error is at least one from the group consisting of a sudden change in pump speed and a change in hematocrit level.

8. A method of managing data indicating an operation of an implantable blood pump, comprising:

at a control circuit, receiving data indicative of at least one from the group consisting of physiological activity and operational activity at an implantable blood pump, the data being at least from the group consisting of (i) actual operating data from the implantable blood pump coupled to the control circuit and (ii) simulated operating data from a discrete testing apparatus coupled to the control circuit;

at the control circuit, determining whether the received data is from the testing apparatus; and

at the control circuit, controlling an activity of the control circuit based on a determination that the received data is from the testing apparatus.

9. The method of claim 8, wherein the method further includes:

storing the received data in a memory; and

when the received data is determined to be from a testing apparatus, storing an indication of the determination in the memory and classifying the received data as simulated operating data.

10. The method of claim 8, further comprising:

storing the actual operating data in a data log; and

omitting the simulated operating data from the data log containing the actual operating data.

11. An apparatus for testing operation of a control circuit, the control circuit configured to monitor operation of an implantable blood pump, the apparatus operatively couplable to the control circuit and discrete from the control circuit and the implantable blood pump, the apparatus comprising:

a memory for storing instructions for simulating operation of the implantable blood pump;

a processor configured to generate simulated operational data of the implantable blood pump based on the stored instructions; and

a communication interface for transmitting to the control circuit the simulated operational data and an indication that the operation data is simulated.
