Boston Scientific Vercise Gevia
Boston Scientific · Model Vercise Gevia
DBS System Next generation rechargeable DBS system compatible with the Vercise Cartesia™ Directional Lead to provide the first and only rechargeable with MICC Directional System2 for DBS with Full-Body MRI access.
Key tips
- ·Never bypass a radiation interlock to "just get the image" - this is one of the few true zero-tolerance rules in BMET work.
- ·Trend image-quality phantom results over time - drift shows up before an outright failure does.
- ·Portable/mobile units take real physical abuse from transport - check wheel locks and cable strain reliefs more often than fixed units.
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.
RF coil fault / poor SNR
HighSymptoms: Low signal-to-noise, shading, or a dead region in images; coil not detected or fails the coil check.
Root cause: Damaged RF coil element, a coil-cable / connector fault, or a preamp fault.
Gradient fault / image distortion
HighSymptoms: Geometric distortion, gradient-amplifier faults, acoustic change, over-temperature trips.
Root cause: Gradient-amplifier fault, gradient-coil cooling problem, or a gradient-coil fault.
Cryogen / cold-head / compressor fault
HighSymptoms: Rising helium boil-off, cold-head noise or stall, He level dropping, compressor alarms.
Root cause: Cold-head at end of life, a helium-compressor fault, or a chilled-water problem.
Chilled water / cooling fault
MediumSymptoms: System-cooling alarms, gradient or RF over-temperature, scans aborting.
Root cause: Facility chilled-water supply, the heat exchanger, or internal pumps.
Patient table / positioning fault
MediumSymptoms: Table will not dock, drive or index; landmarking errors.
Root cause: Table drive, docking sensor, or encoder fault.
Reconstruction / host / network fault
MediumSymptoms: Recon errors, host hangs, images will not reach PACS.
Root cause: Recon or host computer fault, or the network / storage.

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.
- ·Daily QC per modality: image-quality phantom test
- ·Tube and detector inspection
- ·Annual state-required radiation safety survey
- ·Vendor-scheduled preventive maintenance
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: Poor SNR / shading / a dead region with one RF coil
- Swap in a known-good coil of the same type and repeat the scan.
- Run the coil-check / coil-QA tool.
- Inspect the coil housing and cable for damage; reseat the connector.
- Scan the ACR / QA phantom and compare SNR to baseline.
- Quarantine and exchange the faulty coil.
Symptom: Rising helium boil-off / cold-head noise / He level dropping
- Log the helium level and boil-off trend daily.
- Check the cold-head sound and the compressor pressures against spec.
- Confirm the chilled-water supply temperature and flow.
- Schedule a cold-head / compressor service before the level reaches the OEM action point.
- Escalate urgently - never let the magnet approach a quench threshold.
Symptom: Gradient fault / image distortion / gradient over-temperature
- Note the gradient-amplifier error.
- Check the gradient-coil cooling and the chilled-water loop.
- Review the amplifier fault log.
- Run gradient diagnostics / calibration.
- Escalate a gradient-amplifier or gradient-coil fault to the OEM.
Symptom: Patient table will not dock, drive or landmark
- Check for an obstruction and the docking sensor.
- Run the table self-test.
- Inspect the drive and encoder.
- Confirm the landmark laser and its alignment.
- Replace the drive / encoder or refer as isolated.

Documents & Manuals
Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Flash may be protruding from the lumen of the catheter shaft. If this flash is present in the catheter, there is the potential of an embolization resulting from the flash detaching from the device during the procedure.
- RECALL
Missing holes: Catheters are missing the catheter's side holes.
- RECALL
Excess strands of resin may exist in the lumen near the hub of certain batches/lots of the Mach 1 Guide Catheters. If this excess resin is present in the catheter, there is the potential of an embolization resulting from the excess resin detaching from the device during the procedure.
- RECALL
Boston Scientific is voluntarily recalling one lot/batch of Katzen Infusion Wires because they have identified that the label on the carton may indicate a different length device than what is actually in the carton. The affected batch was manufactured using the Katzen Core Assembly of 146 cm, instead of a 177cm assembly.
- RECALL
One lot of product, Stainless Steel Greenfield Vena Cava Filter, may have the incorrect expiration date of 2008-07 and the correct date is 2008-06.
- RECALL
The PT2 J-tip labeled guide wires may be missing the pre-formed J-tip. As a result, guide wires may have a straight tip instead of a pre-formed J-tip.
- RECALL
Lack of assurance of sterility (pre-sterilization bioburden limits exceeded)
- RECALL
Boston Scientific discovered through an internal inspection process that the PTFE (polytetrafluoroethylene) coating is not consistently adhering to the transition area of the distal end of the guide wires which may cause PTFE to flake off.
- RECALL
Gaps were identified between polymer segments on the 7F Wiseguide Guide Catheter in which the PTFE was not properly laminated to the braid of the catheter. This delamination of the PTFE from the braid could compromise the device delivery.
- RECALL
There have been reports of detachment at the bond between the carrier capsule and the outer sheath of the Greenfield Vena Cava Filters with 12 Fr Femoral introducer Systems manufactured before Marcyh 10, 2004. If the capsule should detach during an implantation procedure, there is a risk of cardiac and pulmonary embolization.
- RECALL
The device has the potential for overheating its transformer and has the potential for fire hazard.
