FDA flags Boston Scientific Accolade pacemaker software fix as a Class I recall, covering 1.4 million implants

The agency's most serious recall class applies to an in-office software update, not a device removal — and no working pacemaker need be explanted, with the FDA stating prophylactic replacement is not recommended before high battery impedance is confirmed.

The FDA has designated Boston Scientific’s software correction for its Accolade family of pacemakers a Class I recall — the agency’s most serious category, reserved for situations in which use of a device can cause serious injury or death. The action covers two paired records initiated March 19, 2026, that together reach 1,404,232 implanted devices worldwide.

This is a software correction, not a device removal. No one is being asked to explant a working pacemaker. Boston Scientific is distributing a software update, Brady Software Maintenance Release 6 (SMR6), to be applied during routine in-office device-check appointments across the Accolade, Proponent, Essentio, Altrua 2, Visionist, and Valitude lines.
