Bard Crosser
Bard · Model Crosser
Facilitates central lumen CTO recanalization via atherectomy. Utilizes high-frequency mechanical vibration. Frontline therapy. Maximizes therapeutic options.
Key tips
- ·When no category-specific guidance fits, default to the manufacturer's own service manual and the general troubleshooting method in the Engineer's Guide.
- ·Run an incoming and annual electrical safety test regardless of how niche the device is.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Generator will not deliver mechanical vibration output
HighSymptoms: No output at the catheter transducer, output fault on the generator, treatment cannot start.
Root cause: Failed transducer connection, generator power-amplifier fault, or a jumper-cable / interconnect problem with the FlowMate injector.
FlowMate injector will not prime or deliver saline
MediumSymptoms: No flush at the catheter, injector motor stalls, low-flow alarm.
Root cause: Air not fully purged, a kinked or misloaded line, or a worn injector drive.
Foot switch / activation control fault
MediumSymptoms: Output does not start when the foot switch is pressed, or runs continuously.
Root cause: Fluid ingress or contact wear in the foot switch, or a damaged foot-switch cable.
Interconnect cable / connector damage
LowSymptoms: Intermittent generator-to-injector communication, connector loose, error on power-up.
Root cause: Repeated flexing and connect/disconnect cycles at the jumper cable and power cords.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Follow the manufacturer's PM schedule
- ·Perform incoming and annual electrical safety testing per facility biomedical program
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: No output when treatment is started
- Verify both the generator and injector power switches are on and both units powered.
- Confirm the jumper cable and foot switch are fully seated per the installation guide (foot switch into the injector, jumper injector-to-generator).
- Check the catheter transducer connection at the generator.
- Substitute a known-good foot switch and jumper cable to isolate the fault.
- If output still fails with good cabling, refer the generator for amplifier service.
Symptom: FlowMate injector not delivering flush
- Re-prime the line and confirm all air is purged.
- Check the line for kinks and that it is loaded correctly in the injector.
- Listen for the drive motor - a stall or no motion points to the drive assembly.
- Verify the foot switch triggers the injector.
- Replace the injector drive if it will not run under load.
