Infuse Bone Graft Litigation

Medtronic, manufacturer of Infuse Bone Graft, is facing lawsuits from patients claiming injuries after use of the allegedly defective product. Plaintiffs further allege that the company hid side effects and misled the public about the safety of its product. Medtronic is also accused of marketing the product for unapproved uses, resulting in additional injuries, some permanent.

Medtronic, a worldwide medical technology company with executive headquarters in Dublin, Ireland and operational headquarters in Minneapolis, Minn., became a leader in the spinal surgery industry with the manufacture of its Infuse Bone Graft.

The product was released into the market following its FDA approval in 2002. Just four years later, the popularity of spinal-fusion surgeries involving a genetically engineered human bone-growth protein (such as Infuse Bone Graft) grew to cover 25 percent of all such surgeries.

Infuse Bone Popularity

The popularity of spinal-fusion surgeries grew to cover 25 percent of all such surgeries.

With back pain reportedly ranking as a leading cause of disability in the United States, the company’s sales for devices used in spinal surgeries reached billions in annual revenues. But a study published by the Journal of the American Medical Association (JAMA) also revealed that these types of surgeries were associated with increased hospital costs and a greater risk of complications, some serious, if used in ways not approved by the FDA.

While FDA approval for the product existed for its use in a patient’s back only in the lumbar (lower) spine, the JAMA publication found that complications followed its use in both lumbar and cervical (relating to the neck) fusion procedures. And a 2008 FDA public-health notification issued in 2008 said that using Infuse Bone Grafts in non-approved ways, such as for cervical spine surgeries, heightened the risk of complications, including swelling of the neck and throat.

A 2008 lawsuit filed in California claimed that the off-label use of Infuse for a neck surgery is what killed a 74-year-old woman. Other patients have filed thousands more lawsuits.

Medtronic has since been accused of marketing its Infuse product for off-label uses that have allegedly contributed to patient injuries, and in some cases, death.

Medtronic’s handling of adverse-event reports has also been scrutinized, with over 1,000 reports, including four patient deaths, not appropriately and timely relayed to the FDA until approximately five years past the deadline. A spokesperson for the federal agency was reported to have said that the records provided were not deemed to be of any new public benefit due to the dated information contained in each report.

Medtronic’s chief scientific, regulatory and medical officer, Richard Kuntz, said in a 2016 news report, “We’ve sent it to the FDA… and there has been no action. It’s just kind of a no-issue.”

Medtronic was also investigated by the U.S. Department of Justice, ending in a $40 million payout to settle allegations of illegal kickbacks to doctors as incentive to use its Infuse product.

Meet Some Infuse Plaintiffs

The majority of plaintiffs (85 percent) who filed lawsuits against Medtronic, the hospitals where their spinal surgeries were performed and/or the surgeons who performed them, alleged that the Infuse Bone Graft was used in their surgeries in an off-label way that does not meet the requirements for FDA approval.

Infuse Patient: Medtronic Advised Surgeon

An Oklahoma woman allegedly injured by Medtronic’s Infuse Bone Graft lost her ability to sue the manufacturer when the U.S. Supreme Court declined to hear her petition challenging an appeals court decision.

Patricia Caplinger claimed that a sales representative from Medtronic was in the operating room during her spinal surgery and advised the surgeon to use Infuse in a way not approved by the FDA.

Inproper Use of Infuse

Caplinger argued that the company was aware of an FDA public health notification that warned physicians of life-threatening complications that could be associated with off-label uses of Infuse.

Not only was it not an approved use of the product, but Caplinger further argued that the company was aware of an FDA public health notification distributed in 2008 that warned physicians of life-threatening complications that could be associated with off-label uses.

Caplinger sued Medtronic for injuries she incurred following her surgery including a condition called drop foot, due to bone overgrowth, and accused the company in the lawsuit of promoting its Infuse product for uses never determined to be safe or effective by the FDA.

However, an earlier case in 2008, Reigel v. Medtronic, established a precedent that medical device companies were given broad immunity from liability when the FDA has approved the product for any use, and not specific to what it is actually used for. An attorney for Caplinger said it doesn’t make sense to bar a patient from suing a company when it is promoting a product for a use not approved by the FDA because it may be unsafe.

The company argued that all patients filing lawsuits against it alleging similar claims of liability, which equates to about 85 percent of pending litigation, are barred from suing the manufacturer based on a legal decree of preemption. Preemption means that federal laws overrule state laws having to do with consumer/patient protection, essentially siding with Medtronic in its alleged efforts to “develop new patient treatments.”

First Jury Trial – Keim v. Medtronic

In December 2016, a Missouri judge refused to dismiss a lawsuit filed against Medtronic for injuries to the plaintiff allegedly caused by the Infuse Bone Graft. Judge Mark H. Neill did not entertain Medtronic’s preemption argument in plaintiff Trisha Keim’s personal injury suit, and instead set the case for trial.

Product liability expert David Prince of Mitchell Hamline School of Law said in a news report that the ruling was “a very big deal” for the thousands of plaintiffs still waiting on the sidelines. The outcome can also make a difference in potential settlement negotiations and the amount of payouts.

Medtronic Paid $22 Million in Settlements

In 2014, Medtronic paid a total of $22 million to settle about 950 claims from plaintiffs allegedly injured after Infuse was used in their spinal surgeries. The settled lawsuits accused the company of manipulating studies and engaging in misleading marketing tactics.

The company said that the settlement was rendered to “disputed claims” and confirmed that the compromise was in no way an admission of liability. Medtronic said it stood by its product, which has been used in more than 1 million patients since FDA approval in 2002.

The company projected spending $120 million to $140 million on settlements — including the $22 million one — in the fourth quarter that year.

Infuse Patients, UCLA Settle

Two patients who received Infuse Bone Grafts at the University of California Los Angeles (UCLA) later sued the teaching hospital, surgeon Jeffrey Wang and Medtronic for alleged injuries resulting from the off-label, or improper, use of the product. The plaintiffs, Ralph Weiss and Jerome Lew, alleged that in both surgeries Medtronic’s Infuse product was used in ways not approved by the FDA.

Settlement Fact

UCLA settled with Weiss and Lew for a combined $8.45 million.

The patients further alleged that Wang failed to inform them of a financial relationship between the surgeon and the product manufacturer. The lawsuits claimed that Wang received hundreds of thousands of dollars in grants and royalties from Medtronic.

UCLA settled with Weiss and Lew for a combined $8.45 million, with Weiss receiving a little more than $4.25 million. Medtronic also settled with Lew for an undisclosed amount.

UCLA said it only settled so the school and its medical program could “move forward,” but it did not respond to any of the allegations made by the plaintiffs.

Medtronic Settles DOJ Case

Medtronic paid $40 million to the U.S. Department of Justice (DOJ) to settle charges that it had violated the Anti-Kickback Statute (AKS). The AKS is a part of the federal False Claims Act (FCA) and was designed to ensure a physician’s independent medical judgment in making decisions affecting a patient’s health, free from enticement by companies such as Medtronic.

The governmental alleged that between 1998 and 2003 Medtronic paid kickbacks to physicians in various forms, including sham consulting agreements, royalties and lavish trips.

Shareholders Sue Medtronic

Medtronic’s shareholders brought their own lawsuit against the company, alleging it made misleading statements regarding Infuse. While the manufacturer denied any wrongdoing, it agreed to settle for $85 million.

The settlement resolves, among other claims, Medtronic’s failure to disclose how much of its success of Infuse was dependent upon it being used in off-label manners. Shareholders further alleged that Medtronic’s Infuse sales, as well as its shares, fell after the company’s disclosure of the DOJ investigation.

In December 2016, a second shareholder lawsuit was revived by the 8th U.S. Circuit of Appeals following a lower court’s ruling that the plaintiff shareholders filed their suit too late. The appeals court’s decision said that shareholders would not have been aware of potential problems concerning Medtronic’s Infuse studies until the 2011 publication of an article in The Spine Journal that called Medtronic’s alleged fraudulent actions into question.

Medtronic will now have to answer to the plaintiffs, including West Virginia Pipe Trades Health and Welfare Fund, the Employees’ Retirement System of the State of Hawaii and Germany’s Union Asset Management Holding AG.
