Finding NeMo

With severe stroke or head trauma patients, normal methods of treatment and monitoring can be risky. Moving someone to and from a CT or MRI scan, for example, requires transport and maneuvering. Now, Swiss company NeMoDevices provides an easier solution: light. The technology could prevent dangerous secondary injuries.

“I think [this technology] is important because it saves life, avoids disability, and therefore saves costs for the community,” Keller says.

Founded in 2007 by CEO Emanuela Keller of University Hospital in Zurich and her colleagues at ETH Zurich, NeMoDevices uses light to measure oxygenation and blood flow in the brain, all with a machine as small—and as portable—as a cell phone. In September, Keller, an MD in the ICU at University Hospital, presented the results of NeMo’s pilot study to the Annual Meeting of the Neurocritical Care Society in San Francisco.

Two small disposable devices work with the diminutive equipment, a patch and a probe. The patch is helpful for stable patients and provides a non-invasive way to measure brain blood flow through the skin and tissue. The probe incorporates fiber optics and allows for necessary pressure monitoring in addition to blood and oxygen tracking in more severe situations.

NeMoDevices is in talks with the Mayo Clinic Florida for a potential study in 2011.
