Recall of Device Recall PROPONENT MRI Pacemaker

According to U.S. Food and Drug Administration, this recall involved a device in United States that was produced by Boston Scientific Corporation.

What is this?

A correction or removal action taken by a manufacturer to address a problem with a medical device. Recalls occur when a medical device is defective, when it could be a risk to health, or when it is both defective and a risk to health.

    Implantable pulse generator, pacemaker (non-CRT) - Product Code LWP
  • Reason
    Boston scientific has received reports of intermittent over-sensing of the minute ventilation (mv) sensor signal with certain boston scientific pacemaker and cardiac resynchronization therapy pacemaker systems (pacemakers).
  • Action
    On December 19, 2017 the firm sent a letter to all their medical consignees stating the following: December 2017 Dear Doctor, Boston Scientific has received reports of intermittent oversensing of the Minute Ventilation (MV) sensor signal with certain Boston Scientific pacemaker and cardiac resynchronization therapy pacemaker systems (pacemakers). MV sensor signal oversensing may cause pre-syncope or syncope due to periods of pacing inhibition. This MV behavior may occur with any manufacturers pacing lead system, but Boston Scientific has determined it to be more likely for affected Boston Scientific pacemakers using Medtronic or Abbott/St. Jude (Abbott) leads implanted in either the right atrium (RA) or right ventricle (RV). Boston Scientific is actively developing a software update designed to automatically detect and resolve this MV sensor signal oversensing behavior. We anticipate submitting the software update to Regulatory Agencies in March 2018 and pending approval, will release it as soon as possible thereafter. Until this software update is available, Boston Scientific has additional re commendations to mitigate this risk for affected pacemaker systems. Root Cause Investigation The MV sensor in Boston Scientific pacemakers can be used for RightRate" (rate adaptive pacing), Respiratory Rate Trend, or AP Scan"1. When the RA/RV pacing leads and lead terminal connections are operating as intended, the MV sensor signal is appropriately filtered and therefore is not detected by the pacemaker or displayed on electrograms (EGMs). However, intermittency related to the lead or pacemaker-lead connection2 has the potential to create a transient high impedance condition. A high impedance condition may subsequently alter the MV sensor signal such that it becomes visible on EGMs and potentially subject to oversensing on the RA or RV channels. For a technical description of the Boston Scientifics MV sensor, please refer to Appendix A. Engineering analysis and

  • Manufacturer comment
    “We take a patient-first approach to assessing the applicability of every recall and communicate to regulatory bodies in all geographies where the recalled device is sold,” Boston Scientific said in a statement to ICIJ. “We have coordinated several recalls across many countries in a timely manner,” the company said, adding that it complies with all national laws, which can often vary and require different processes for reporting information or taking action on recalls. The company said it uses a rigorous and uniform process to take action on recalls and that “when we initiate a field action (e.g. recall, safety alert), every customer who has received an affected product receives a communication that includes a letter for the physician.”
