New, exciting changes for DBS patients

Activa PC+SResearchers at the University of Washington are developing a new device to help monitor and record tremor changes in Deep Brain Stimulation (DBS) patients. With the new Activa PC+S device, developed by Medtronic, stimulation can be turned on and off, leading to battery conservation of the device — an issue for current DBS technology. A person with essential tremor could detect their tremor and adjust the stimulation within clinician set limits.

The Medtronic Activa PC+S sits in the chest with electrodes, electrical conductors that make contact with a nonmetallic part of the circuit, wired into the brain. The electrode doesn’t have to be used to stimulate but since it is present, it can still be used to record tremor to later analyze for adjustments, if needed.

Researchers are also developing an Android smartwatch app to communicate with the piece of hardware from smartphones and smartwatches. When the patient senses the tremor, they can enable stimulation and modify within parameters in real time without a computer or without visiting their physician.

This device is not yet FDA-approved and still in early research stages. For more information visit, The Daily.
