Reason for Recall

Updated software, Brady software maintenance release 6 (SMR6), is now available for the ACCOLADE" family of pacemakers and cardiac resynchronization therapy pacemakers (CRT-Ps)1 and the advisory population is expanding to include all CRT-P and dual-chamber extended life (DR-EL) devices. Dual chamber modes are specifically indicated for treatment of the following: " Conduction disorders that require restoration of AV synchrony, including varying degrees of AV block " VVI intolerance (i.e., pacemaker syndrome) in the presence of persistent sinus rhythm " Low cardiac output or congestive heart failure secondary to bradycardia

Distribution Pattern

worldwide

Lot / Code Information

The advisory population includes all models listed; however, the bounding differs by battery type: " All serialized DR-EL pacemakers and CRT-Ps from the ACCOLADE family are included in the advisory population. " ACCOLADE DR-SL and SR-SLs with a use-by-date (UBD) on or before 30 June 2025 are included in the advisory population. Model number alone will not precisely identify individual DR-SL or SR-SL devices in the advisory population.

Frequently Asked Questions

A software recall means the device's embedded software or firmware has a defect that could affect its performance or safety. Many software recalls are corrected through firmware updates that can be applied without physically replacing the device. For implantable devices, the update may be delivered wirelessly during a routine clinic visit. For external devices, the manufacturer may provide updated software files or replacement units. Contact your healthcare provider to determine whether your specific device and software version are affected and what action is recommended.

Class I recalls indicate a reasonable probability of serious adverse health consequences or death from the defect. Class II recalls involve products that may cause temporary or medically reversible adverse health consequences, or where serious consequences are remote. Class III recalls cover products not likely to cause any adverse health consequences, typically involving technical regulatory violations. The classification guides urgency, Class I recalls require immediate action, while Class III may simply involve returning a product or acknowledging a labeling change. Always read the specific recall notice for recommended patient actions.

Report problems with medical devices to the FDA through MedWatch at 1-800-FDA-1088 or online at FDA.gov/safety/medwatch. Healthcare facilities are required by law to report device-related serious injuries and deaths. Patients and consumers can also report voluntarily. Include the device name, manufacturer, model number, and a description of the problem and any patient outcome. Reports from patients and clinicians help the FDA identify emerging safety signals and may trigger investigations that lead to recalls of dangerous devices.
