## Abstract

In an implanted medical device system, an internal controller, external power transmitter and methods for performing battery conditioning are disclosed. According to one aspect, an internal controller includes processing circuitry configured to cause conditioning of an internal battery of the internal controller responsive to a direction from an external power transmitter in radio communication with the internal controller.

## Claims

### Claim 1

An external power transmitter of an implanted medical device system, the external power transmitter comprising processing circuitry configured to:
cause display of messages to a patient to enable the patient to schedule a later time to perform conditioning of a battery of an internal controller implanted in the patient;
receive input from the patient that selects a scheduled a time to perform the conditioning; and
cause the internal controller to perform the conditioning at the scheduled time.

### Claim 2 (depends on 1)

The external power transmitter of claim 1, wherein the processing circuitry is further configured to cause discontinuance of a transfer of transcutaneous energy transfer system (TETS) power during the conditioning.

### Claim 3 (depends on 2)

The external power transmitter of claim 2, wherein the processing circuitry is further configured to turn off a misalignment alarm during the conditioning.

### Claim 4 (depends on 1)

The external power transmitter of claim 1, wherein the processing circuitry is further configured to count a number of failed battery conditioning attempts.

### Claim 5 (depends on 4)

The external power transmitter of claim 4, wherein the processing circuitry is further configured to report when the number of failed battery conditioning attempts exceeds a threshold.

### Claim 6

A method implemented in an external power transmitter of an implanted medical device system, the method comprising:
causing display of messages to a patient to enable the patient to schedule a later time to perform conditioning of a battery of an internal controller implanted in the patient;
receiving input from the patient that selects a scheduled time to perform the conditioning; and
causing the internal controller to perform the conditioning at the scheduled time.

### Claim 7 (depends on 6)

The method of claim 6, further comprising causing discontinuance of a transfer of transcutaneous energy transfer system (TETS) power during the conditioning.

### Claim 8 (depends on 7)

The method of claim 7, further comprising turning off a misalignment alarm during the conditioning.

### Claim 9 (depends on 6)

The method of claim 6, further comprising counting a number of failed battery conditioning attempts.

### Claim 10 (depends on 9)

The method of claim 9, further comprising reporting when the number of failed battery conditioning attempts exceeds a threshold.
