Medtronic plc posted nearly 50% year-over-year growth in its cardiac ablation business this quarter, with a 72% increase in revenue in the U.S., largely driven by pulsed field ablation.

The company alleged infringement of six of its patents by two units under the Natus umbrella of companies, but this conflict is also under review in Delaware district court, promising a drawn-out conflict that may not resolve for years.

Subtyping is what made precision medicine in cancer a reality. And for successful drug discovery in all its stages, finding subtypes in Alzheimer’s disease is all but imperative.

At the 2025 Alzheimer’s Association International Conference (AAIC), one of the bigger splashes was made by a cardiovascular drug.

Alterity Therapeutics Ltd. helped develop a new neuroimaging biomarker called the multiple system atrophy index (MSA-AI), which looks to be a more reliable biomarker for tracking disease progression of MSA. Developed using deep learning methods, the MSA-AI offers a superior, objective and quantifiable measure of brain atrophy in MSA patients.

Cortec GmbH implanted its brain-computer interface (BCI) system, Brain Interchange, into a stroke patient in late July, joining a host of other companies conducting clinical trials of their BCI technologies to help people affected by neurological conditions recover lost function and improve their quality of life.

Boston Scientific Corp. received CE mark certification under the Medical Device Regulation for its Intracept intraosseous nerve ablation system, bringing another treatment option to patients with chronic pain.
