In 2016, medical system big Abbott issued a recall for its MitraClip cardiac device — “a Class I recall, the most serious type,” the FDA mentioned.
“Use of this device may cause serious injuries or death,” an FDA notice in regards to the recall mentioned.
But neither the producer nor the FDA really recalled the system or suspended its use. They allowed medical doctors to proceed implanting the clips in leaky coronary heart valves in what has turn out to be a typical process.
In a notice, the producer defined, “Abbott is not removing product from commercial distribution.” Rather, Abbott revised directions to be used and required medical doctors who implant the clips to bear coaching.
When it involves medical units, recollects can embody not solely “removals,” wherein the system is faraway from the place it’s used or offered, but in addition “corrections,” which deal with the issue within the area — as an example, by repairing, adjusting, relabeling, or inspecting a tool.
“It’s very oxymoronic,” mentioned Rita Redberg, a heart specialist on the University of California-San Francisco and former editor-in-chief of the journal JAMA Internal Medicine. “A recall makes it sound like it’s recalled. But that is not actually what it means.”
Though the FDA and federal regulations name these actions recalls, they may be described extra aptly as “non-recalls.” And they’ve occurred repeatedly lately. For occasion, along with other Abbott devices, merchandise made by Medtronic, Abiomed, and Getinge have had recollects that left them in use.
Safeguarding the Public
Recalls that go away what the FDA identifies as doubtlessly harmful merchandise within the market can increase the query: Do they do sufficient to guard the general public?
There are different methods to deal with recollects. In announcements about products as assorted as crib bumpers, pool drain covers, bicycle helmets, and low mugs, the Consumer Product Safety Commission routinely alerts customers to cease utilizing recalled merchandise and get in touch with the producers for refunds, repairs, or replacements. The National Highway Traffic Safety Administration repeatedly advises customers to convey recalled cars again to the seller to have them fastened. When the U.S. Department of Agriculture and the FDA announce food recalls, they routinely inform customers to return or discard the meals.
In some circumstances, a medical system that’s the topic of a recall could be stored in the marketplace safely as a result of there’s a easy repair, mentioned Sanket Dhruva, a heart specialist and an affiliate professor at UCSF who has studied FDA oversight of units. In different circumstances, recollects that don’t take away units from the market can present unwarranted reassurance and go away the general public in danger, Dhruva mentioned.
From 2019 by way of 2023, there have been 338 Class I medical system recollects, 164 of which had been corrections and 174 of which had been removals, FDA spokesperson Amanda Hils mentioned.
Some merchandise bear recall after recall whereas they continue to be in the marketplace. Products within the MitraClip line have been the topic of three rounds of recollects, none of which eliminated units from use.
“When deciding whether a recall warrants device removal from the field, the FDA considers the frequency and severity of adverse events, effectiveness of the corrective actions that have been executed, and the benefits and risks of preserving patient access to the device,” FDA spokesperson Audra Harrison mentioned.
Where recalled units have already been implanted, “removal” doesn’t essentially imply eradicating them from sufferers’ our bodies. “When an implanted device has the potential to fail unexpectedly, companies often tell doctors to contact their patients to discuss the risk of removing the device compared to the risk of leaving it in place,” the FDA web site says.
The FDA allowed the recalled MitraClip units to stay in use “because the agency believed that the overall benefits of the device continued to outweigh the risks and the firm’s recall strategy was appropriate and adequate,” Harrison mentioned.
The FDA evaluations the recall methods that producers suggest and infrequently supplies enter to make sure the general public shall be protected, Hils mentioned. The company additionally displays the effectiveness of recollects and, earlier than terminating them, makes certain the technique was carried out, Hils mentioned.
Abbott, the maker of MitraClip, mentioned the system has been confirmed protected and efficient “based on more than 20 years of clinical evidence and has profoundly improved the lives of people living with mitral regurgitation,” a situation wherein blood flows backward by way of the guts’s mitral valve. The situation can result in coronary heart failure and loss of life.
“With MitraClip, we’re addressing the needs of people with MR who often have no other options,” firm spokesperson Brent Tippen mentioned.
Speaking of the MitraClip recollects, Redberg mentioned, “So hard to imagine these are effective actions in protecting patients.”
In 2021, for Medtronic’s StealthStation S7 cranial software program, the corporate and the FDA despatched a distinct message.
StealthStation is an elaborate system of screens and other equipment that guides neurosurgeons utilizing devices within the mind — as an example, to biopsy or minimize out tumors. Drawing from CT scans, MRIs, and different imaging, it’s meant to point out the situation of the surgical devices.
In reference to a Class I November 2021 recall, the FDA web site mentioned potential inaccuracies in a biopsy depth gauge might lead to “life-threatening injury (such as hemorrhage, unintended tissue damage, or permanent neurological injury), which could lead to death.”
The FDA web site defined what Medtronic was doing about it.
“The recalling firm will provide a warning and instructional placard to be applied to impacted systems,” the web site mentioned. “Until a software update is available, ensure you are following the instructions below to prevent the issue from occurring,” it suggested medical doctors.
In an announcement to KFF Health News, Medtronic spokesperson Erika Winkels mentioned the protection and well-being of sufferers is the corporate’s major concern, and sure points “can be safely and effectively remedied with a correction on site.”
Richard Everson, a neurosurgeon and an assistant professor at UCLA, famous that the 2021 recall allowed medical doctors to proceed utilizing unaffected StealthStation options, a profit for sufferers and services relying on them.
“But, I mean, then you could ask, ‘Well, why don’t they just disable the view [of the brain] that’s bugged?’” Everson mentioned. “Why would they give you the option of looking at an inaccurate one?”
“That’s kind of a strange solution,” he mentioned.
The FDA lists the 2021 recall as still open, explaining “not all products have been corrected or removed.”
That recall was not the final phrase on issues with StealthStation. Since then, the producer has submitted hostile occasion stories to the FDA describing bother in circumstances involving varied variations of StealthStation.
In a September 2022 case, steering offered by a StealthStation system was allegedly off the mark, a process was aborted, and, when the affected person awoke, they “had almost no speech for two days,” in accordance with a Medtronic report. In the report, Medtronic mentioned there was “insufficient information to determine the relationship of the software to the reported issue.”
In a February 2024 case, after mind surgical procedure, an MRI discovered that the operation “missed the tumor” and that different tissue was eliminated as an alternative, in accordance with a report Medtronic submitted to the FDA. In the report, Medtronic mentioned that when an organization consultant examined the system, it carried out as meant.
In March 2024, Medtronic recalled variations of StealthStation S8 with out eradicating them from hospitals. The firm mentioned on the time that it will present a software update.
“Software updates are available to correct the anomalies identified in the 2021 S7 and 2024 S8 recalls and are actively being deployed,” Medtronic’s Winkels informed KFF Health News in a July e mail. “While the software updates for the 2021 S7 recall are complete in the US, they remain ongoing in some international regions.”
In June 2023, Abiomed issued an pressing medical system correction for its Impella 2.5 intravascular micro axial blood pump, which helps the guts. In sufferers with a sure sort of substitute coronary heart valve, there was a threat of “destruction of the impeller blades,” which might trigger “low flow” and “embolization of the fractured impeller material,” an entry on the FDA website mentioned.
“Clinicians are cautioned to position the Impella system carefully in patients,” the FDA web site mentioned, amongst different directions.
The up to date directions “provide technical guidance to mitigate the risk of rare complications,” Abiomed spokesperson Ryan Carbain mentioned. There had been no product removals and no stories of hostile occasions “related to product design or manufacturing,” Carbain mentioned.
Another set of medical units, Cardiosave Hybrid and Rescue Intra-Aortic Balloon Pumps made by Getinge of Sweden, have failed persistently, in accordance with FDA information.
The units — that are positioned within the aorta, a serious artery, to help the guts — had been the topic of eight Class I recalls from December 2022 to July 2023. All had been corrections quite than removals, a KFF Health News evaluation discovered.
In a May 2024 letter to well being care suppliers, the FDA mentioned that, within the earlier 12 months, it had obtained almost 3,000 adverse event reports associated to the balloon pumps. It was referring to stories of malfunctions and circumstances wherein the merchandise might need brought on or contributed to a loss of life or damage. Of these, 15 reportedly concerned critical damage or loss of life, the FDA mentioned.
During the summer season of 2023, the FDA famous that “alternative treatments are limited” and mentioned the units might continue to be used.
But, in May, the FDA modified its stance. The company suggested well being care services to “transition away from these devices and seek alternatives, if possible.”
“These recommendations are based on our continued concerns” that the producer “has not sufficiently addressed the problems and risks with these recalled devices.”
Getinge despatched KFF Health News written solutions from Elin Frostehav, the corporate’s president of Acute Care Therapies.
“There is no question that we would have liked to have solved these issues in full much earlier,” she mentioned.
As a results of the FDA’s May motion, the corporate “immediately paused proactive marketing” of the balloon pumps within the United States, and it’s promoting them solely to prospects who haven’t any options, Frostehav mentioned.
“We are working with the agency to finalize remediation and product update solutions,” Frostehav mentioned.
‘Known Possible Complications’
Abbott’s MitraClip system contains tiny clips implanted within the coronary heart’s mitral valve and the gear used to implant them. The equipment encompasses a steering mechanism with hand controls and a catheter that’s threaded by way of a serious vein, usually from an incision within the groin, to position a number of clips within the coronary heart.

Worldwide, more than 200,000 people have been handled with MitraClip, in accordance with an Abbott web site.
The 2016 MitraClip recall described circumstances wherein “the user was unable to separate the implantable Clip from the delivery system.”
In a news release on the time, Abbott mentioned it had “received a small number of reports” wherein that occurred.
Those circumstances “resulted in surgical interventions to remove the delivery system or replace the mitral valve, and it is expected that any future similar incidents would also require surgery to correct the problem,” the FDA mentioned in a 2016 notice. “There was one patient death in these cases as a result of severe comorbidities following surgery.”
Years later, one thing related occurred.
In February 2021, a clip was implanted in an 81-year-old affected person however the physician couldn’t separate the clip from the delivery system, in accordance with a report Abbott filed with the FDA. The affected person was transferred to surgical procedure, the place the supply system “had to be cut down in order to detach the clip.”
The affected person then underwent an operation to switch the mitral valve, and, hours later, the affected person was introduced again to surgical procedure to deal with bleeding, the report mentioned.
The affected person “coded” the subsequent day and died from an aortic bleed, the report mentioned.
In the report back to the FDA, the producer blamed “case-specific circumstances.”
“Cardiac arrest, hemorrhage and death are listed” within the system directions “as known possible complications associated with mitraclip procedures,” the corporate mentioned. “There is no indication of a product issue with respect to manufacture, design or labeling.”
The third MitraClip recall, initiated in September 2022, cited an “increase in clip locking malfunctions.”
Most of the reported malfunctions weren’t related to hostile outcomes, the FDA said then. Treatment with MitraClip “remains within the anticipated risk levels,” the corporate informed prospects.
As with the 2 earlier recollects, the third suggested medical doctors to observe the system’s directions. But the 2022 recall recognized a contributing issue: the way in which the system was made.
“Abbott has identified a contributing cause … as a change in the material properties of one of the Clip locking components,” the corporate mentioned in a 2022 letter to customers.
“Abbott is working on producing new lots with updated manufacturing processing and raw material,” the corporate wrote. In the identical letter, Abbott informed medical doctors that, within the meantime, they might use the units that they had in inventory.
Six days later, a clip opened while locked and a affected person died, in accordance with a report the producer submitted to the FDA.
“There is no evidence that death was related to the device but it was likely related to the procedure,” Abbott wrote.
Now, virtually two years later, the 2022 recall stays open, in accordance with the FDA web site, and “not all products have been corrected or removed.”
