In a boon for companies developing brain-computer interface (BCI) technologies, researchers have used a BCI and artificial intelligence to restore touch sensations in a bionic arm.

Boston Scientific Corp. reported positive data for two key atrial fibrillation therapies at AF Symposium 2025 on January 17. In late-breaking data presentations, the ADVANTAGE AF trial for the Farapulse PFA system met its primary endpoints, showing a 2.3% safety event rate and 63.5% effectiveness rate in treating persistent atrial fibrillation (AF) patients, with an 85.3% symptomatic AF recurrence-free rate. Additionally, a sub-analysis of the OPTION trial demonstrated that the Watchman FLX device significantly reduced bleeding outcomes compared to oral anticoagulants.

Natera Inc., a developer of cell-free DNA testing, provided an update on its product portfolio at the J.P. Morgan Healthcare Conference on Jan. 15. The company disclosed a new version of the Signatera assay that leverages the genome. Natera said the test, now available for research and clinical use, enables bespoke assay design from a whole genome sequence of a patient’s tumor.

Esocap AG aims to transform the treatment of eosinophilic esophagitis with its drug delivery technology, ESO-101, designed to increase mucosal contact time and drug deposition in the esophagus. Data from the recent ACESO study showed that ESO-101 was safe and well tolerated and improved both histologic and endoscopic outcomes in patients with active eosinophilic esophagitis.

As 2025 makes its debut, one of the topics gaining momentum in health care is the diagnosis and potential treatment of neurodegenerative diseases, a scourge that threatens to overwhelm society and drain treatment budgets around the world. One company looking to find solutions to the oncoming neurodegenerative disease tsunami is privately held Sunbird Bio Inc., which is developing blood-based diagnostic platform for neurological diseases like Alzheimer’s and Parkinson’s disease.

The U.S. FDA posted a draft guidance that would revisit a 2014 final guidance on sex-specific data drawn from medical device clinical trials, expanding the scope to include considerations of gender.

Xeltis BV completed enrollment in the EU pivotal trial for its restorative vascular access conduit, Axess. The prospective study will investigate the patency, safety and performance of Axess in adult patients with end-stage renal disease requiring vascular access to start or maintain hemodialysis therapy.

An artificial intelligence-based tool developed by researchers in the U.K. is helping doctors identify people at risk of developing atrial fibrillation. Data from the ongoing Find-AF pilot study shows that the algorithm can comb through patients’ electronic health records and detect red flags which could indicate whether they are at risk of developing the heart condition.

The U.S. FDA’s draft guidance for reporting of deviations from clinical study protocols lends some insight as to the definition of a deviation, but the agency highlights some concerns about related compliance activities.

Merit Medical Systems Inc. received an early holiday gift this year, reporting that its Wrapsody cell-impermeable endoprosthesis has received premarket approval from the U.S. FDA and plans to begin commercialization of the device there in 2025.
