Class II U.S. Food and Drug Administration

Boston Scientific Corporation Lux-Dx II Plus, Arrythmia detector and alarm, Model M312 recall: For some patients upgraded from a LUX-Dx M301 device to a new Model M302

Recall published 6 months ago

For some patients upgraded from a LUX-Dx M301 device to a new Model M302 or M312, the new ICM device is not collecting PVC Burden data (both M302/M312) or monitoring for Bradyarrhythmia and Pause (M312 only). In addition, for these devices that are not being monitored, the LATITUDE Clarity programming screens have discrepant information, indicating that the monitoring is enabled for these features in one location and not enabled in another location.

The hazard: Device safety concern

This is a device enforcement record. Check whether the remedy is a correction, a software update or a removal before changing anything.

What the notice says: For some patients upgraded from a LUX-Dx M301 device to a new Model M302 or M312, the new ICM device is not collecting PVC Burden data (both M302/M312) or monitoring for Bradyarrhythmia and Pause (M312 only). In addition, for these devices that are not being monitored, the LATITUDE Clarity programming screens have discrepant information, indicating that the monitoring is enabled for these features in one location and not enabled in another location.

Why it matters: The FDA recorded an enforcement action against this device. Most device recalls are corrections rather than removals, so the device often stays in use while the manufacturer issues a fix.

  3. If you are a facility, quarantine affected stock and log the correction.

Replacements, repairs and reimbursement

Device remedies run through the supply chain, so the route depends on who sold you the unit.

  • Contact the distributor or clinic named on your paperwork and quote the recall number on this page. They will tell you whether the remedy is a repair, a replacement or an instruction update.
  • If the device was billed to insurance or Medicare, the replacement is usually billed the same way; you should not face a second deductible for a recall.
  • Keep every piece of correspondence. If a recalled device caused harm, that paper trail is what a claim rests on.
  • Consumer-purchased devices such as monitors and test kits are normally replaced free, with return shipping paid.
