Health Canada Endorsed Important Safety Information on certain Guidant/Boston Scientific pacemakers and defibrillators

June 26, 2006

URGENT MEDICAL DEVICE SAFETY INFORMATION & CORRECTIVE ACTION

Subject: Potential for malfunction in a subset of implantable pacemakers, cardiac resynchronization therapy pacemakers (CRT-Ps), and cardioverter defibrillators (ICDs) manufactured by Guidant Cardiac Rhythm Management (CRM), a Boston Scientific Company

Dear Health Care Professional,

This letter is intended to inform you of important safety information regarding the potential for malfunction in a subset of INSIGNIA® and NEXUS® pacemakers, CONTAK RENEWAL® TR/TR 2 CRT-Ps, and VENTAK PRIZM® 2, VITALITY® and VITALITY 2 ICDs. Our records indicate that you have implanted or are monitoring patients with one of these devices.

As a precautionary measure, Guidant has initiated action to retrieve from hospital and sales force inventory all non-implanted devices within this well-defined subset. Consistent with Heart Rhythm Society and Independent Panel (Robert J. Myerburg, MD, chair) recommendations for timely, transparent and responsible actions, Guidant is taking this product retrieval action before our investigation is complete and prior to finalizing patient care recommendations.

Description of Issue

Guidant has recently confirmed five (5) reports of device malfunction associated with the failure of a low-voltage capacitor from a single component supplier. Some capacitors from specific lots may perform in a manner that leads to device malfunction, including intermittent or permanent loss of therapy or premature battery depletion. One device malfunction was discovered at the time of implant, while four devices were implanted and subsequently required replacement. To date, approximately 49,800 devices have been distributed and approximately 27,200 devices have been implanted worldwide.

Clinical Implications

Patients with affected pacemakers or CRT-Ps may experience intermittent or permanent loss of output or telemetry, or premature battery depletion. Patients with affected ICDs may experience inappropriate sensing or premature battery depletion. There have been no reported patient deaths associated with this issue. There have been two reports of pacemaker patients experiencing syncope associated with loss of pacing output.

Projected Rate of Occurrence

We are very early in our investigation and do not have sufficient information to provide a projected rate of occurrence. We are continuing to diligently gather and analyze data to provide physicians with additional information regarding projected rate of occurrence for implanted devices. This information will be provided in a subsequent communication as soon as it is available.

Recommendations

  • Physicians are asked to perform an in-clinic follow-up visit as soon as possible for all patients with implanted devices from this subset. A list of patients with susceptible devices specific to your clinic is included with this communication. At this follow-up visit, please look for the following device behaviors, which may be indicative of capacitor malfunction: premature battery depletion, intermittent or permanent loss of therapy or telemetry, fault codes, pacing or sensing abnormalities, or loss of daily measurements. Your local representative can provide additional technical guidance to assist in the evaluation of devices in this subset. Please document and report any observations of abnormal behavior through your local representative or Guidant Technical Services.
  • Guidant requests that all non-implanted inventory in this subset be returned to Guidant. Your local sales representative can provide a complete list of device model and serial numbers and is available to coordinate the retrieval process.

Warranty Supplement Program

Guidant's Warranty Supplement Program, subject to certain conditions, provides a no cost replacement device.
