The recalled devices were manufactured from May 2004 through February 2009 and distributed from May 2004 through February 9, 2009. The defibrillators that fall under the recall have serial numbers in which the last six numbers are under 200000. Defibrillators obtained prior to February 14, 2009 should have serial numbers under 200000 and fall under the recall.

The recall follows a series of letters sent in February and March 2009 to distributors and customers with recommendations and instructions for customers on specific steps to mitigate the identified problems with the device. The February letter instructed customers to replace their batteries every three years. The March follow-up letter instructed customers to download new software for their devices and to remove any battery replacement reminder labels. The new software will detect and prevent potential battery problems that could develop with 123A Lithium batteries in the future.

Software upgrades can be found at www.zollaedplusbatteryhelp.com.

ZOLL will send an email notice to all customers who included their email address as part of their contact information. ZOLL will also publish information about the recall in industry magazines.

Class 1 recalls are the most serious type of recall and involve situations in which there is a reasonable probability that use of these products will cause serious injury or death.

In Canada, 2,416 patients had the Medtronic defibrillators implanted as of February 2005, with 613 of them having been removed or replaced as of June 2007.

In 2005, Medtronic announced that it was recalling two heart defibrillators because they had been linked to at least four deaths and one injury. 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 some of the recalled defibrillators failed to charge properly, a defect which can result in the late delivery or no delivery of cardiac shock therapy. Medtronic had actually discovered the problem with its defibrillators in 2003, but did not disclose the problems immediately.

In October, Medtronic agreed to pay $130 million to settle U.S. claims it hid the defects in the defibrillators, $55 million more than it proposed in a July settlement, people familiar with the agreement said at the time. The company agreed to the higher amount after more claims were filed over the heart defibrillators than the parties expected, the people said.

But the October settlement was not the end of Medtronic’s defibrillator woes. That same month, Medtronic suspended sales of the Sprint Fidelis Leads after receiving reports of 5 fatalities linked to lead fractures. A lead is a wire that connects an implantable defibrillator to the heart. It is through the lead that a defibrillator is able to sense when a patient’s heart rhythm is out of sync. When it breaks, the defibrillator can emit a massive and painful shock. And in the worse case scenario, the fractured lead can prevent a defibrillator from sending a necessary, lifesaving shock to the heart.

Just last week, lawyers for Medtronic went before the US Supreme Court to ask that people injured by defective medical devices and drugs should not be allowed to sue manufacturers if those products have been approved by the Food & Drug Administration.

Following the recall, it was learned that Medtronic had been receiving reports that indicated the Sprint Fidelis Lead had a higher-than-normal fracture rate for months. The incident has raised questions about the Food & Drug Administration’s (FDA) regulation of medical devices, and of the Medtronic’s response to early reports of lead problems.

Medtronic has acknowledged in a Securities and Exchange Commission (SEC) filing that the Senate Finance Committee has requested information about ties between the medical-device industry and practicing physicians and information about Medtronic’s suspended distribution of its Sprint Fidelis family of defibrillation leads. The Senate panel is probing the FDA’s oversight of medical-device components.

Medtronic said in the same SEC filing that it is the subject of a Justice Department probe into illegal physician payments. The U.S. attorney’s office for the Eastern District of Pennsylvania asked for information on payments or gifts to physicians or physician’s groups related to the purchase of the company’s cardiac stents and cardiac-therapy devices.

The U.S. attorney also asked Medtronic to provide documents related to its relationship with a specific customer. The customer wasn’t identified in the SEC filing. In September, the SEC began an informal probe of Medtronic, seeking information about possible violations of the Corrupt Foreign Practices Act, which is meant to stop bribes to foreign officials.

This is not the first time Medtronic’s relationships with physicians has come under scrutiny. Earlier this year, Sen. Charles Grassley, R-Iowa, requested information from Medtronic about the company’s payments to orthopedic surgeons, and questioned whether they improperly influenced physician decisions about which products to use.

Monetary agreements with physician consultants are common in the medical device industry, where doctors are paid for their work developing products and then, in some cases, for helping to train other doctors in how to use the products. Medtronic insists that it only provides physicians with compensation that is fair, relative to current market values, and is compliant with the law.

The risk of a defective wire is low. Medtronic said that about 2.3 percent of the estimated 235,000 patients with the defective wire, or 4,000 to 5,000 people, would experience a lead fracture within 30 months of implantation. But learning through tests that one’s defibrillator has a faulty lead can create agonizing decisions for patients and doctors.

One decision is whether to remove the wire, a procedure that carries some risks, or leave it in place alongside a replacement.

Removal carries significant risk of damage to the heart and veins through which the wire wends from the defibrillator, a generator implanted under the skin near the collarbone.

When working properly, defibrillators deliver a potentially life-saving shock if the heart beats rapidly and purposelessly in a rhythm known as ventricular fibrillation. A surge from the device can restore a life-supporting heart rhythm.

If the Medtronic lead, called the Sprint Fidelis, were faulty, it could simply signal the patient to check with a doctor about a possible malfunction. Or it could deliver a painful, body-rocking shock when such a jolt is not needed. Or the device could fail to deliver a life-saving shock when it is needed.

The malfunction does not involve conventional pacemakers without defibrillators, Medtronic said.

Dr. David R. Broudy, a cardiologist and electrophysiologist who implants defibrillators in Seattle, said Monday that he was in the habit of telling all patients about potential complications when he implants defibrillators. He said there was a 2 to 3 percent chance of complications, including serious infections and malfunctions in leads and other parts.

He says he has 92 defibrillator patients who have a Sprint Fidelis lead, although on Monday he received calls from only three of them. Like other doctors, he said he would send letters alerting patients who do not call.

Medtronic also said that it would send letters to all Sprint Fidelis patients.

Defibrillator patients generally carry cards that contain the lead’s identifying numbers, which in the Medtronic recall are 6930, 6931, 6948 and 6949. Each patient is being asked to come in for computerized testing that could detect abnormalities in resistance and other electrical functions that could signal an impending fracture in the lead.

In Seattle, Dr. Broudy said that in trying to assess what to do for each of his patients with the potentially defective lead, he would check factors like the number of times the device had appropriately delivered shocks and the degree of a patient’s anxiety.

“There are different needs for different patients,” he said. Those who have had frequent abnormal heart rhythms, he said, may be more dependent on the device than others. Even patients in whom no evidence of possible cracks in the leads is found will need to have their Medtronic defibrillators reprogrammed.

The quandary will be for those found to have a fractured lead.

Doctors can insert a new lead into the vein if there is room for it, attach it to the heart, and then put a cap on the old one.

The risks of surgically removing the lead depend in part on how long it has been in place. Scar tissue forms around the lead after it is implanted. Removal can produce bleeding from torn veins and damage heart muscle. The risk of such complications ranges from 1.4 percent to 7.3 percent.

Dr. John Kassotis, director of cardiac electrophysiology at the State University of New York Downstate Medical Center in Brooklyn, said, “You can definitely take the leads out if they have been in less than six months and usually if it is less than two years.”

Patients who do need surgical removal of the lead should go to doctors and medical centers that have extensive experience in performing such procedures, experts interviewed Monday said.
