US-based Natus Medical has launched the US Food and Drug Administration (FDA)-cleared Grass MR Conditional/CT Cup Electrodes.
These electrodes feature 28% longer lead lengths for easier application.
According to Natus Medical, Grass MR Conditional/CT Cup Electrodes are the longest safe electrode in 1.5T and 3T MR environments. The FDA has authorised them as MR conditional and granted 510(k) clearance.
The approval will allow simple preparation for safe and quick transitions from electroencephalogram (EEG) testing to magnetic resonance imaging (MRI) scans.
The electrodes have also been tested to show low artifact levels in MRI environments, said Natus Medical.
The Grass MR Conditional/CT Cup electrodes feature deep-cup disposable single electrodes measuring 282mm and arrays extending to 270mm. This longer design simplifies its application.
The added length provides technologists more flexibility to access disconnect points before MRI exams transport. This minimises strain on patient contacts and ensures easy reach for any 10-20 placement location.
Natus Medical Neuro CEO Chris Landon said: “Our launch of the Grass MR Conditional / CT Cup Electrodes is the result of a journey that started by listening to the challenges that technologists, radiologists, and other healthcare professionals have experienced for decades while working with shorter MR-compatible electrode leads.
“Among the many benefits, longer leads provide more room for bundling and wrapping a patient’s head with just one fixed exit point.”
Grass MR Conditional/CT Cup electrodes are designed to reduce the risk of skin breakdown by eliminating the need to disconnect and reconnect patients during EEG monitoring in critical care.
Its simple and intuitive detaching process allows quick and safe transfers from busy ICUs to MRI exams and back. This minimises interruptions to EEG recordings, benefiting continuity and potentially leading to faster diagnoses.
The latest electrodes mark a new chapter in the Grass story and Natus EEG history, which dates to 1935 with the launch of the Grass Model I Electroencephalograph.
In 2013, Natus Medical acquired the Grass Technologies Product Group from Astro-Med.
Recently, the American electrode developer submitted an FDA 510(k) premarket notification to the US FDA for its Natus point-of-care EEG device.
