LONDON – Heart disease is now known to be both a cause and an effect of serious COVID-19 infection, with more than 1 in 10 patients who have underlying cardiac conditions being killed by the virus, while others with no previous record of cardiovascular problems are suffering significant COVID-19 induced weakening of their hearts.

Two judges with the U.S. Court of Appeals for the Federal Circuit sided with the Patent Trial and Appeal Board (PTAB) in a patent dispute between Oticon Medical and Cochlear, but the third judge, Pauline Newman took issue with the decision. Newman said the majority applied “an improper analytical technique” to determine that the preamble to a patent does not limit the related claims, despite that prior art cited to dispute the patent had been “disavowed by the preamble.”

Waltham, Mass.-based Thermedical Inc. has received a breakthrough device designation from the U.S. FDA for its saline enhanced radiofrequency (SERF) ablation system and Durablate catheter in the treatment of ventricular tachycardia (VT). The system uses a new means of biological heat to precisely deliver ablation therapy to the heart.

Quidel Corp., of San Diego, has scored another win at the U.S. FDA, receiving emergency use authorization (EUA) for the Lyra Direct SARS-CoV-2 Assay to allow direct sample processing. What’s special about this assay is that it does not require an up-front sample extraction. Instead, it uses a reformulated buffer that replaces that process with a simple 10-minute heat step, saving about 50 minutes in processing time.

Edwards Lifesciences Corp. has gained a CE mark for its Pascal transcatheter valve repair system to treat tricuspid regurgitation (TR). It was previously approved for mitral regurgitation treatment. Due to the pandemic, Edwards has paused new enrollments in its ongoing mitral and tricuspid pivotal clinical trials.

Balt USA LLC, of Irvine, Calif., has received a thumbs up from the FDA to begin an IDE trial of its Squid liquid embolic device for the treatment of chronic subdural hematoma (cSDH). The nonadhesive agent offers a minimally invasive option for a disabling neurological condition that often requires brain surgery to correct.

The FDA has granted an emergency use authorization (EUA) for the home sample collection kit made by Austin, Texas-based Everlywell Inc., which can be run on two lab-developed tests. However, the agency has also shut down a Gates Foundation-backed effort in Seattle to develop another home sample collection kit even though the organization behind the effort has been authorized by state health authorities. The FDA announced the news about the Everlywell EUA with the stipulation that the user of the kit has completed an online questionnaire that is subsequently reviewed by a health care professional.
