1×1 LTE tDCS Device

Limited Total Energy tDCS For Susceptible Subjects

The Soterix Medical 1×1-LTE is the only tDCS device optimized for susceptible populations with features optimized to reduce anxiety and sensation including SmartScan™, Relax™, and Tickle™. Additionally with an exclusive feature of Soterix Medical LTE™, makes it the most intelligent power and transient management system for currents up to 1.5 mA.

Limited Total Energy™ (LTE)

Limited Total Energy for tDCS (LTE-tDCS) was developed exclusively by Soterix engineers. LTE limits the voltage and power required for tDCS through the use of adaptive ramp-up stimulation and intelligent energy management for currents up to 1.5 mA. The Soterix Medical 1×1 tDCS-LTE includes the most advanced transient protection in the industry, an electrode becoming temporarily disconnected, for example due to subject movement. In addition, should resistance increase to atypical levels, LTE-tDCS will automatically reduce the applied current so as to maintain a low voltage.

Soterix Medical tDCS-LTE Device

Soterix Medical tDCS-LTE is a unique system that provides an additional safety margin, without compromising efficacy, when stimulating susceptible subjects.

Proven to Limit Power During tDCS

The difference between conventional tDCS and tDCS-LTE is that conventional tDCS applies a fixed ramp slope while tDCS-LTE varies ramp intensity to limit power delivery. Soterix tDCS-LTE also limits power transients that might occur during tDCS due to sudden changes in resistance. tDCS-LTE further enhances abort-protection features already enabled on all Soterix 1x1 devices. Finally, tDCS-LTE alerts the operator when a high-power condition occurs and automatically activates LTE to reduce power consumption.

Focus on the subject, not the device with Open-Panel™ controls

The Soterix Medical Open-Panel™ control system was developed to allow simple dose setting in seconds. With easy-click control knobs to set stimulation duration and intensity, and back-lit status display visible even at a distance. SmartSCAN™ provides a constant indication of electrode quality and with Soterix Medical LTE™ automatically managing dose, allows you to focus on your subject from set-up, to stimulation, to ramp-down.

No drop-down menus. No hidden settings. No external computer.

Device Features

Soterix Medical 1×1 features were optimized by our biomedical engineers consulting closely with leading TBI rehabilitation clinics and pediatric neurologists. Designed for simple set-up, provide intelligent warning of a fault condition, and allow for adjusting for patient comfort , these features facilitate reliable and tolerated tDCS. The Soterix Medical SmartScan™ feature is central in all Soterix tDCS devices to allow reliable set-up and monitoring. The Relax™, Tickle™, and TrueCurrent™ innovations were developed for the 1×1 tDCS platforms. Limited Total Energy (LTE™) is available exclusively on the 1×1-LTE platform.

Limited total energy provides adaptive ramp-up stimulation technology to limit the required voltage.

Advanced transient protection, should an electrode become temporarily disconnected. LTE-tDCS will automatically reduce the applied current so as to maintain a low voltage should resistance increase to atypical levels.

Provides a continuous visual indication of electrode quality before and during stimulation.

From pre-stimulation set-up, to during stimulation monitoring, to post-stimulation confirmation, the Soterix Medical SmartScan™ feature provides an intuitive and clear indication of electrode contact quality. Use the SmartScan™ during set-up to adjust electrodes and head-gear for optimal fit. During stimulation, SmartScan™ provides a constant indication of electrode quality and can be monitored during adjustments (e.g. addition of saline to drying electrodes). After stimulation, SmartScan™ confirms a successful trial. Because “resistance” is not meaningful for tDCS, SmartScan™ was developed by Soterix Medical engineers to provide clinical investigators with a simple to read indication of contact quality.

Clearly indicates the actual current supplied at the moment.

What other devices promise, the 1×1 tDCS delivers. The back-lit display can be monitored during stimulation ramp up to confirm that the targeted current intensity is achieved.

May be used to supply a very weak current prior to tDCS to help condition the skin.

Tickle™ may be used to both condition skin prior to tDCS and for naïve subject anxious about stimulation. A custom on-off waveform pattern generates mild and brief sensation under electrodes.

Allows the clinician to use a simple sliding bar to transiently decrease the current from the pre-set value, for example, based on subject feedback.

Based on feed-back from leading clinical centers, Soterix Medical exclusive feature, RELAX™, accommodates subjects who may be anxious when stimulation is initiated or during the course of stimulation. The RELAX™ slider may be adjusted from full to reduced intensity based on subject perception without interrupting or aborting stimulation.

Simple and intelligent sham waveforms.

An automatic stimulation sham feature that is engaged with a simple switch. Auto-sham automatically calculated and produces a sham waveform based on the indicated “real” waveform. For example, for a corresponding real waveform of 1.5 mA and 10 minutes. auto-sham will provide a ramp up/down to 1.5 mA at the start of of stimulation, and again after 10 minutes, with the timer automatically adjusted such that the total run time us exactly matched to the real case. Based on the Soterix Medical Open-Panel™ design principle: with no complicated programming or hidden drop-down menus required.

Dose Guidelines for Susceptible Subjects

In tDCS one size does not fit all, and nowhere is this more sensitive than in susceptible populations. Soterix Medical scientists are working with leading pediatric neurology clinical research centers to refine and optimize dose strategies. With access to Soterix Medical Solution services and Software, tDCS 1x1-LTE users are part of this community and dialogue.

Fully compatible and expandable with all Soterix Medical 1x1 accessories

Every 1x1 accessory is optimized for simple and consistent set-up, robust and safe performance, and ease-of-use. Since "one size does not fit all" in tES, the 1x1 accessory set provides the flexibility to optimize performance. From EASYpads™ to EASYstraps™, Soterix Medical 1x1 accessories are designed and validated specifically for the 1x1 platform. Our scientific team is ready to help you select the best accessory set to make your 1x1 the most optimized platform adjustable to any application.

tDCS Software with Capacity for Individualized Analysis

Optimization of electrode montage for brain targeting and individual subject customization has never been as easier as with Soterix Medical's Neurotargeting software. With recognition that placing an electrode "over" a target does not support rational tDCS does design, the Soterix Medical Suite of software tools allow simple and automatic optimization. Soterix Neurotargeting software also provides high-resolution current flow visualization that can be used to support publications, presentation and proposals. Only Neurotargeting allows analysis of the role of individual variation in tDCS and HD-tDCS dose including uploading of individual scans. The 1x1-tDCS LTE can be upgraded at any time to Soterix Medical’s exclusive HD-tDCS using the 4x1-Adaptor device, while continuing to leverage the unique safety features of LTE.
