On October 15, 2007, Medtronic announced that it was suspending sales of the Sprint Fidelis lead, a vital component in its implantable defibrillators. According to Medtronic, the Sprint Fidelis lead, a wire that connects the Medtronic defibrillator to the heart, could fracture inside a patient’s blood vessel, delivering a massive electrical jolt. This malfunction can cause extreme pain, or in the worse case scenario, it can be fatal. At least 5 deaths have already been linked to a malfunctioning Sprint Fidelis lead used with an implantable Medtronic defibrillator.
The Sprint Fidelis lead have been used in implantable Medtronic defibrillators since 2004, and most patients who received the devices since then have the faulty leads. Sprint Fidelis leads were used only in cardiac defibrillators -- or complex devices with defibrillation capacity -- and not in conventional pacemakers. Some patients with congestive heart failure use devices that included this defibrillation ability, and those were among the machines that use the Sprint Fidelis lead.Medtronic Defibrillator Lead Recall
Medtronic decided to suspend sales of the Sprint Fidelis lead after a company review of 30 months of data showed that the defibrillator lead had a continuing fracture problem. According to the company’s own estimate, approximately 2.3%, or 4,000 to 5,000 people with a Sprint Fidelis lead will experience fracture within 30 months of having a Medtronic defibrillator implanted. Those patients whose Sprint Fidelis lead fractures will require a dangerous surgical procedure to have the wire replaced.
For the unlucky patients who experience a fracture of a Sprint Fidelis lead, three things can happen. If they are fortunate, the implantable defibrillator will beep, alerting the patient to seek immediate medical attention. Or, the fracture can create a massive electrical shock that causes the patient extreme and sudden chest pain. But most disturbingly, the fracture of a Sprint Fidelis lead can deplete the Medtronic defibrillator’s battery. If this happens, the Medtronic defibrillator can fail to deliver a necessary, life-saving shock to the heart.
In addition to suspending sales of the Sprint Fidelis lead, Medtronic also recalled all unused leads on the market. The company also advised patients with Medtronic implantable defibrillators that may have used the defective Sprint Fidelis lead to see their doctors. Replacing leads on an implantable defibrillator is far more risky than replacing the device itself, so the company was not advising that patients with a Sprint Fidelis lead have those replaced. Rather, it urged physicians to reprogram the defibrillators to minimize the problem. Medtronic said the new programming would allow the implantable defibrillators to better monitor and warn of problems with the Sprint Fidelis leads.
Medtronic Defibrillator Charging Problem
On April 16, 2004 Medtronic announced that it was recalling two heart defibrillators because they have been linked to at least four deaths and one injury. Medtronic said that some of these defibrillators have failed to charge properly which can result in the late delivery or no delivery of cardiac shock therapy.
The charging problem involves the Medtronic Micro Jewel II Model 7223Cx and the Medtronic GEM DR Model 7271 implanted cardioverter-defibrillators. Medtronic said that most of these devices were implanted in 1997 and 1998. About 1,800 are thought to be still in use.
These devices are used to shock the heart into normal rhythm after patients suffer irregular heartbeat or fibrillation, which are rapid, life-threatening arrhythmia's, originating in the lower chambers of the heart. The defibrillators are implanted surgically in the chest. When a cardiac arrhythmia occurs, the capacitor is charged and the device delivers the appropriate shock.
Medtronic said that with the suspect defibrillators, the capacitors may take longer than normal to charge near the end of the battery service life and could cause a delay in delivery or no delivery of shock therapy. A delay or no delivery of shock therapy can be life threatening.

Medtronic Sprint Fidelis Lead Victim Asks Lawmakers to Restore Consumers Rights
Jun 12, 2008 | Parker Waichman Alonso LLP
A Pennsylvania woman went to Capitol Hill yesterday to ask lawmakers to overturn a Supreme Court ruling that has stripped consumers of their right to sue for injuries caused by defective medical devices. Bridget Robb was shocked more than two dozen times due to a defective Sprint Fidelis Lead attached to a Medtronic implantable defibrillator. Because the Supreme Court has taken away her right to sue the company, Robb said she was forced to go to Congress for...
Pacemakers Vulnerable to Hackers, Researchers Say
May 29, 2008 | Parker Waichman Alonso LLP
Pacemakers can be hacked - relatively easily. Now a research team that was able to hack the implantable defibrillators that keep sick hearts beating steadily are telling federal regulators that the problem needs to be addressed. In recent years, over 100,000 patients in the US have been implanted with a defibrillator device - or pacemaker - that has helped to reduce medical visits. The device and its technology enable patient information to be sent to a bedside monitor that...
Heart Device Patients Often Unaware of Recalls
May 16, 2008 | Parker Waichman Alonso LLP
It seems that many patients who have been implanted with heart devices are not aware of recent recalls and do not understand the dangers they might face, this according to two new surveys. Although the surveys are small, they do indicate a lack of understanding among doctors and patients about heart disease and the devices used to treat it, said Dr. Bruce Wilkoff, director of cardiac and tachyarrhythmia devices at Cleveland Clinic Wilkoff, who is familiar with the surveys. "There are...
Medtronic Announces Job Cuts, Restructuring
May 7, 2008 | Parker Waichman Alonso LLP
Still struggling in the wake of last year's Sprint Fidelis Defibrillator Lead recall, medical device maker Medtronic Inc. says it plans to cut 1,100 jobs worldwide as part of a restructuring plan. Medtronic's business has been hurt, not just by the Sprint Fidelis recall, but by the declining worldwide demand for implantable defibrillators, which has been shrinking since Medtronic and competitors recalled faulty products in 2005.Medtronic suspended sales of the Sprint Fidelis Leads in...
Medtronic Unit Agrees to Consent Decree
Apr 28, 2008 | Parker Waichman Alonso LLP
An agreement has been reached by a unit of Medtronic Inc. on a consent decree with the U.S. Food and Drug Administration (FDA) over quality system improvements for its external defibrillators. The agreement—which is subject to court approval—addresses concerns raised by the FDA during inspections and outlines actions Medtronic's Physio-Control subsidiary must take to resume unrestricted distribution of the portable electronic devices. Physio-control is a maker of external...
