The NeuroOne OneRF Radiofrequency Ablation System is indicated for creation of radiofrequency lesions in nervous tissue for functional neurosurgical procedures.

The OneRF™ Ablation System components consist of the: - Radiofrequency (RF) Generator and Accessories - Generator Interface Cable (GIC), Cart and Foot Pedal (optional) - sEEG-RF Probe (with Universal Cable Assembly) and Ablation Accessories - Temperature Accessory, Spacer Tubes, Stylet and RF Connector Box The OneRF™ Ablation System uses radiofrequency ablation to create lesion (s) in an area of nervous tissue that the neurosurgeon has identified for ablation. This is accomplished by diagnostically locating the area to ablate using the implanted Stereoelectroencephalography (sEEG). Once the area of ablation is located, the generator and ablation accessories are taken to the patient with implanted sEEG(s). The sEEG(s) now function as an sEEG-RF Probe for RF ablation. To perform the ablation the Temperature Accessory (TA) is inserted into the sEEG-RF Probe to the predetermined electrode contact location using the specified spacer tube. A stylet may be used to ensure the lumen is patent prior to inserting the TA. The universal cable assembly remains attached to the sEEG-RF Probe while its cables are disconnected from the diagnostic head box. One (monopolar) or two (bipolar) cables from the universal cable assembly are inserted into the radiofrequency connector box (RFCB) depending on the contact area(s) to be ablated. The TA is also connected to the RFCB is attached to the Generator Interface Cable which is attached to the Generator. Temperature and time are used to create lesion (s).

The Evo® sEEG System is intended for temporary (less than 30 days) use with recording, monitoring, and stimulation equipment for the recording, monitoring, and stimulation of electrical signals at the subsurface level of the brain.

The NeuroOne Evo® sEEG System is comprised of the Evo® sEEG Electrodes (which includes Anchor Bolt Cap and Stylet) accompanying Cable Assemblies, and the Evo® Anchor Bolts. The Evo® sEEG System components are provided sterile and are single use only. The Evo® sEEG Electrodes and Anchor Bolts are temporarily placed (less than 30 days) at the subsurface level of the brain. The system is designed to be used in stereoelectroencephalography (sEEG) procedures. The sEEG electrodes, by way of the accompanying cable assemblies, are connected to recording, monitoring, or stimulation/response instrumentation commercially available for use with other sEEG electrodes, including the predicate device. The sEEG electrodes are a 0.8mm diameter polyimide electrode with platinum contacts and are available in varying numbers of contacts: 5 to 16 contacts, with an exploration length (recording depth) from 16 to 80mm. The contact height is 2.0mm and spacing is 1.5-3.2mm apart. The Evo® Anchor Bolts are available in 20mm, 30mm, and 35mm lengths, can only be used and placed through a small 2.1mm burr hole drilled in the skull, and should be used only when sEEG depth electrodes are warranted.
