The U.S. has granted final approval to Microvention Inc., a subsidiary of Terumo Corp. based in Aliso Viejo, Calif., for its Flow Redirection Endoluminal Device (FRED) for the treatment of brain aneurysms. The flow diverter – Microvention’s third PMA approval in less than two years – is the first in the U.S. to utilize a self-expanding, braided nitinol mesh to aid in rerouting blood flow away from the weakened area and promote occlusion.

Dublin-based Medtronic plc received a CE mark for its Percept PC neurostimulator to treat neurologic disorders such as Parkinson’s disease. It is the first deep brain stimulation system launched in the EU that integrates the company’s technology to sense and record brain signals, known as Brainsense. It’s intended to enable more personalized treatment driven by that data.

Amyloid and tau proteins are both involved in the disease pathology of Alzheimer’s disease. The diagnostic and treatment research focus has long been on amyloid, which has proven almost entirely fruitless after decades of effort. But tau is becoming better understood, as investigational tau imaging agents offer the ability to visualize its presence in the brain.

Saluda Medical Pty. Ltd., of Artarmon, Australia, made waves in 2019, winning the CE mark for its Evoke closed-loop spinal cord stimulation (SCS) system. The good news kept coming following the publication of results from a pivotal study in The Lancet Neurology.

With many on Wall Street transfixed by the three injectable calcitonin gene-related peptide (CGRP) therapies cleared in the prophylactic migraine market, Satsuma Pharmaceuticals Inc.’s prospects with STS-101 may have gone overlooked, at least until lately.

A single injection of SOD1-targeting RNA into the subpial space, which is below the innermost meningeal layer, was able to spread throughout the spinal cord and, via retrograde delivery, into brain centers that project to the spinal cord in several animal models, including primates.

Seven years after an advisory hearing on the subject, the FDA has determined that cranial electrotherapy stimulation (CES) devices will be slotted as class III devices when used for depression. The decision comes despite a number of irregularities that took place at the February 2012 advisory hearing.
