What This Guide Helps With
Use this guide when a connected catheter, accessory, interface, or external module is not recognized or repeatedly disconnects.
Step-by-Step Troubleshooting
1. Protect the Patient Before Changing Therapy Accessories
Do not disconnect or exchange a therapy-related catheter, accessory, or module while the patient depends on the affected function unless the clinical team has transitioned care appropriately.
Expected outcome: Accessory troubleshooting can be performed without compromising therapy.
2. Identify the Exact Unrecognized Component
Determine which catheter, accessory, or module is not recognized and whether the problem follows one component, one cable, or the generator itself. Record the exact displayed message.
Expected outcome: The affected component and failure pattern are clearly identified.
3. Inspect the Physical Connection
Verify the component is plugged into the correct interface and fully seated. Inspect connectors, pins, sockets, locking features, and housings for visible damage, contamination, or fluid.
Expected outcome: The component is correctly connected with no obvious damage. If reseating restores stable recognition, proceed to final verification.
4. Verify Component Compatibility
Confirm the catheter, accessory, cable, adapter, or module is approved for use with the Medtronic DiamondTemp system and intended configuration.
Expected outcome: Only compatible components remain in the test setup.
5. Inspect Interconnecting Cables
Trace any cable between the generator and affected component. Look for crushed areas, damaged insulation, bent contacts, strained connectors, or loose attachment.
Expected outcome: No external cable defect is found. Any visibly damaged cable is removed from service.
6. Substitute a Known-Good Approved Component
When available, connect a known-good compatible catheter simulator, accessory, cable, or module appropriate to the approved service procedure rather than using a patient-connected device for testing.
Expected outcome: If the known-good component is recognized, the original component or its associated cable is isolated as the likely cause.
7. Power-Cycle After Correct Connection if Appropriate
With the patient removed from dependence on the system, perform a normal shutdown, connect the approved components correctly, and restart.
Expected outcome: The generator initializes and recognizes the component normally.
8. Verify User-Accessible Configuration
Confirm the system is operating in the intended supported configuration. Do not enter protected service menus or modify undocumented configuration values.
Expected outcome: The connected component is compatible with the active system configuration.
9. Perform Final Recognition and Functional Testing
Verify stable recognition through normal setup and approved functional testing. Confirm the component does not repeatedly disappear or reconnect.
Expected outcome: Recognition remains stable and associated functions operate normally. The issue is resolved and troubleshooting can stop.
10. Escalate Generator-Side Recognition Failure
If multiple known-good approved components fail at the same interface, remove the generator from service.
Expected outcome: The system is sent for qualified bench or manufacturer-level evaluation.
If the Problem Persists
Common accessory, cable, connection, and compatibility causes have been ruled out. Remaining possibilities include interface damage, internal communication faults, software or configuration issues, or other service-level problems.
Remove the generator from service, label it Out of Service, and send it for repair or bench evaluation. Use current manufacturer documentation and approved test equipment. Do not attempt board-level repair or protected configuration changes without authorization.
After repair, verify recognition of appropriate approved components and complete required functional testing before return to service. Stopping after isolating the problem beyond external components is proper troubleshooting.
Clinical Use Tip
Never substitute an unapproved catheter or accessory merely to bypass a recognition problem during a procedure.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Clinical staff reported that the DiamondTemp generator would not recognize the connected therapy accessory."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found a damaged interconnecting cable between the accessory and generator."
Resolution
What action was taken.
Example:
"Clinical Engineering replaced the damaged cable with an approved replacement and verified stable accessory recognition and normal system readiness."
Helpful Details to Include (If Known)
- Component not recognized
- Exact displayed message
- Connector condition
- Cable condition
- Compatibility verified
- Known-good component used
- Whether recognition was intermittent
- Restart result
- Functional verification result
- Final device status
Final Thought
Maintain safe continuity of care, confirm compatibility and every external connection before suspecting the generator, use known-good approved components to isolate faults, escalate generator-side failures, and document the confirmed cause.
That is successful troubleshooting.
