Recall record

Recall number: Z-0827-06
Status: Terminated
Initiated: 2006-04-07
Posted: 2006-05-02
Terminated: 2007-04-01
Recalling firm: Boston Scientific Corporation
Product: Guidant CONTAK RENEWAL 4 AVT (model M170). Cardiac Resynchronization Therapy Defibrillator (CRT-D). Sterile EO. Guidant Corporation, 4100 Hamline Avenue North, St. Paul, MN 55112-5798 USA. Cardiac resynchronization therapy defibrillators (CRT-D) provide both atrial and ventricular tachyarrhythmia and cardiac resynchronization therapies. Ventricular tachyarrhythmia therapy is for the treatment of ventricular tachycardia (VT) and ventricular fibrillation (VF), rhythms that are associated with sudden cardiac death (SCD). Atrial tachyarrhythmia therapy is for the treatment of supraventricular tachcardia (SVT) and atrial fibrillation (AF). Cardiac resynchronization therapy is for the treatment of heart failure (HF) and uses biventricular electrical stimulation to synchronize ventricular contractions. This device also uses accelerometer-based adaptive-rate bradycardia therapy. Cardioversion/defibrillation therapies include a range of low-and high-energy shocks using either a biphasic or monophasic waveform.
Product code: NIK Defibrillator, Automatic Implantable Cardioverter, With Cardiac Resynchronization (Crt-D)
Reason for recall: 77 distributed devices may have a cracked layer of insulation in a flexible hybrid circuit, leading to internal shorting during charging such as during routine capacitor formation or for defibrillation. This would likely render the device non-functional, resulting in no output and/or telemetry communications.
FDA root cause: Other
Action: Guidant Sales Representatives are retrieving non-implanted devices April 10-12, 2006. If a device is implanted the physician is sent an Urgent Medical Device Safety Information & Corrective Action letter, April 11-14, 2006. This letter describes the issue, states that Guidant is retrieving all non-implanted devices and that Guidant is currently conducting tests on retrieved devices. Physicians will be advised once more information is available.

About this record

Sourced from the FDA device recall database and the FDA enforcement reports, both ingested from openFDA. The recall record supplies the product, the reason and the product code; the enforcement report supplies the classification. The two datasets are exported by FDA on different days, and the date above is the older of the two, so nothing on this page is newer than it says.

MDM adds the root cause tag, derived from FDA’s own root cause text, and the cross-links to the product code, the clearances named on the record and MDM coverage. Where a recall has not been joined to an enforcement report, no classification is shown.
