In the past few years, AI’s presence has become increasingly widespread across industries and embedded in our daily lives. Most notably, it has completely altered the practice of healthcare as more AI-enabled medical devices enter the market. Many patients are concerned about unexpected injuries from AI mishaps.
They often ask, “Has this technology been tested or are we just guinea pigs?”
Nevertheless, recent product liability and medical malpractice lawsuits allege that the TruDi Navigation System, an artificial intelligence (AI) surgical device, has contributed to patients’ injuries. This raises many issues, including but not limited to product defects, breach of duty of care, and inadequate warnings under tort principles.
Although the FDA began authorizing AI-assisted medical devices in 1995, it has now approved at least 1,357 medical devices that use the mechanism – including TruDi. Despite having obtained approval, the safety and reliability of the system, and many like it, are now being challenged in the ongoing legal proceedings.
Serious Injury Risks Linked to Lawsuits with the TruDi Navigation System
Errors associated with the TruDi Navigation System have been reported to cause a serious range of medical complications, some of which may have long-term or permanent effects on patients.
These risks include:
- Carotid Artery Dissection: Trauma to the carotid artery, potentially resulting in a stroke, severe bleeding, or other neurological deficits.
- Cerebrospinal Fluid (CSF) Leaks: Breaches in the fluid around the brain and spinal cord, which can cause life-threatening consequences.
- Visual Impairment: Harm to the optic nerve or surrounding eye structures, which can lead to partial or complete vision loss.
- Skull Injuries: Accidental damage to the structures at the base of the skull that can happen due to incorrect placement of the instrument.
There can also be additional unplanned procedures to correct the errors in previous procedures. This introduces further risks and health complications.
What is the TruDi Navigation System?
TruDi is a navigation system manufactured by Acclarent, a subsidiary of Johnson & Johnson, and a medical technology company that specializes in ear, nose, and throat (ENT) devices. The system utilizes electromagnetic imaging to aid doctors in performing endoscopic sinus procedures.
After Johnson & Johnson announced an advancement in its products, Acclarent added a machine-learning algorithm to the TruDi Navigation System’s software. The software’s innovations were intended to help surgeons avoid mistakes during invasive surgeries, allowing for safe and long-term solutions for patients. Nonetheless, it faces allegations of misidentifying body parts and causing surgical mistakes that leave patients with lasting injuries.
What Are the Reported Injuries and is the FDA Response Strong Enough to Protect Patients?
Between late 2021 and November 2025, at least 10 people have reported injuries associated with the TruDi Navigation System. In June 2022, Dr. Marc Dean, a surgeon, performed a sinusplasty on Erin Ralph using the TruDi Navigation System to ensure the precise placement of his instruments inside her skull. While the procedure is done to alleviate inflammation and facilitate proper drainage, the TruDi Navigation System had misdirected Dr. Dean.
In the lawsuit, Ralph alleged that the procedure resulted in blood clots because her carotid artery was injured. The next year, Dr. Dean performed another sinuplasty on Donna Fernihough. Not only did Fernihough’s carotid artery “blow,” but she also suffered a stroke on the day of the surgery.
However, Acclarent denies all the allegations set forth by the plaintiffs, and the FDA warns that reports of the TruDi Navigation System’s malfunctions are not sufficient to simply cast the blame for these surgical errors on Acclarent.
The agency finds these claims to be vague and lacking in detail, even though it has received over 1,400 reports regarding medical devices that it has approved. A significant portion of the reports highlight issues with software, algorithms, and programming. The FDA dismissed these reports, saying that its list of approvals is not comprehensive.
