PROPONENT DR Pacemaker Recalled for Unexpected Safety Mode Risk

Boston Scientific is recalling certain PROPONENT DR pacemakers built before September 2018 due to latent battery impedance that could cause unexpected Safety Mode initiation during normal operation.

The agency’s classification

FDA (Devices): Class I

Class I is a situation in which there is a reasonable probability that the use of or exposure to a violative product will cause serious adverse health consequences or death.

This is the agency’s own classification, taken from its notice. The severity score below is our assessment, not the agency’s. How recall classes work

What this means for you

Our assessment, not the agency’s: severity 4/5 (Severe).

The hazard poses a serious risk of illness, injury, or structural failure. Stop using the product immediately and contact the manufacturer for a refund or repair.

Our severity reasoning: The agency classified this recall as Class I — a situation in which there is a reasonable probability that the use of or exposure to a violative product will cause serious adverse health consequences or death. On that classification alone this is scored Severe; a score of Critical is reserved for recalls where a death or serious injury was reported. The agency gives the reason as: "A subset of devices from the ACCOLADE Family of Pacemakers and CRT-Ps, built before September 2018, have an increased potential to initiate Safety Mode during telemetry or other normal, higher-power operations due to latent high battery…"

Plain-English summary

Boston Scientific is recalling certain PROPONENT DR pacemakers (models L201, L209, L211, L221, L231) manufactured before September 2018. Approximately 59,937 units were distributed in the U.S., with additional units distributed to U.S. territories and other locations including Guam and the Northern Mariana Islands, totaling 156,329 affected units.

The recalled devices may experience an increased potential to initiate Safety Mode during telemetry or normal higher-power operations due to latent high battery impedance. Safety Mode is a protective mechanism that, if activated unexpectedly during routine pacing operations, could interrupt normal device function.

Patients can identify whether their device is affected by checking their device's model number, UDI code, and serial number against the detailed recall information provided by the FDA. Further guidance regarding affected devices may be obtained from Boston Scientific or by consulting the official FDA recall documentation.
