Medtronic corporation has announced two significant product advisories which have potential impact on the patients in our practice.  In February, 2005 the marquis family of implantable defibrillators had an advisory released regarding the small risk that these devices could stop functioning.  On October 15th 2007 Medtronic initiated a product advisory on the "Sprint Fidelis" family of defibrillator leads.  This advisory was initiated when it became evident that this lead has a higher then normal chance of fracturing after implantation.  Details regarding both of these product advisories can be accessed by clicking the above links.  Please note a product advisory is not a "recall" and the decision to replace a recalled product can therefore only be made after evaluating the individual patient.  If you have one of the above products implanted, we recommend you contact you arrange to see your cardiologist or contact our office to arrange for further consultation with professionals in this practice.
