The U.S. FDA has given the green light to Xact Robotics Ltd. for its Xact Ace robotic system for computer tomography (CT)-guided percutaneous procedures. The company plans to roll out the system later this year with an initial focus on interventional radiologists.

The U.S. FDA’s interest in harmonizing its regulations for medical devices with an international standard is a matter of record, but the agency has found this to be an enormously complicated task. Kim Trautman, executive vice president for medical device services at NSF International, of Ann Arbor, Mich., told BioWorld that the task of rewriting Part 820 to meet ISO 13485 in the middle is no mean feat, but also that it may be delayed again, this time because of the COVID-19 pandemic.

The next phase of testing for the COVID-19 pandemic will hopefully include the roll-out of tests for neutralizing antibodies for the SARS-CoV-2 virus, but there are some roadblocks. The FDA’s Tim Stenzel said the agency has a limited amount of information to offer regarding emergency use authorizations for these tests, a predicament that might not resolve until several applicants are in and the agency can see some information that will aid in development of performance and validation standards.

Edwards Lifesciences Corp. has scored an approval from the U.S. FDA for the Konect Resilia aortic valved conduit, a ready-to-implant solution for bio-Bentall procedures.

The U.S. FDA has a number of draft guidances in queue thanks to the COVID-19 pandemic, but released two final guidances in mid-July, including the guidance for clinical investigations for prostate tissue ablation devices. Stakeholders pressed the agency to avoid a fixed period of follow-up for such studies due to variability in the elapsed time for device-related adverse events, but the agency stuck to the draft’s mandate for at least a year of follow-up.

Electrocore Inc. has snagged an emergency use authorization (EUA) from the U.S. FDA for use of its Gammacore Sapphire CV noninvasive vagus nerve stimulation (nVNS) to acutely treat asthma exacerbations in known or suspected COVID-19 patients. The hand-held therapy can be used at home and in a health care setting.

Infervision Technology Co. Ltd. has received the green light from the U.S. FDA for its Inferread Lung CT.AI product. The artificial intelligence- and deep learning-based technology automatically performs lung segmentation and identifies and labels different types of lung nodules. According to the 510(k) notification, Inferread Lung CT.AI “is comprised of computer assisted reading tools designed to aid the radiologist in the detection of pulmonary nodules during the review of CT examinations of the chest on an asymptomatic population.”

The use of real-world data (RWD) and real-world evidence (RWE) in regulatory decision-making may seem more aspirational than practical at times, but that state of affairs is changing rapidly. Wendy Rubenstein, director of personalized medicine at the U.S. FDA’s Center for Devices and Radiological Health, said contemporary versions of these real-world sources of evidence “are of progressively higher quality” in recent years, and thus RWE and RWD may soon hit their strides as mature sources of data with which regulators are increasingly comfortable.

Plymouth, Minn.-based Nonin Medical Inc. gained a U.S. FDA 510(k) clearance for its Co-Pilot wireless hand-held multiparameter system (H500). The system is expected to be used by first responders to evaluate various oxygenation and respiratory-related parameters in patients after incidents such as cardiac arrest, traumatic injury, carbon monoxide or smoke inhalation.

The U.S. FDA’s priorities for testing for the SARS-CoV-2 virus have shifted as circumstances have changed, and the agency is putting more emphasis into testing of pooled samples. Toby Lowe, the associate director of the Office of In Vitro Diagnostics and Radiological Health (OIR), said on the July 8 diagnostic town hall that the agency wants to encourage test developers to work on their existing EUAs for pooled sampling.
