Clinical Neurophysiology


Our clinical neurophysiology range features CE marked Medical Devices & FDA cleared intraoperative monitoring or IOM equipment (D185), neurodiagnostics (DS5), sports physiology and basic nerve and muscle research (DS5 and DS7A/AH). We also manufacture the D360 8-Channel Isolated Amplifier and offer a range of neurodiagnostic accessories for use with our electrical stimulators and isolated amplifiers.

Now used worldwide as an effective tool for intraoperative monitoring (IOM) of the spinal cord, the D185 MultiPulse remains the ONLY standalone surgical stimulator with FDA clearance for this technique. With a voltage output of 1,000V and a fixed pulse duration of 50us, it is able to evoked MEPs from the most challenging of patients, allowing effective monitoring of descending motor control pathways during spinal surgery or aortic aneurysm repair.

The DS7A can deliver 100mA or 1A (DS7AH) pulses in response to a TTL trigger.  The bipolar DS5 stimulator converts a variable voltage waveform into an isolated current output of up to +/-50mA.  Still in development, our new DS8R will have the output ranges of the DS7AH, but incorporate a biphasic output and external control capabilities.

We currently offer two isolated amplifiers within our clinical neurophysiology range.  The D360 is a fully MDD CE certified medical device and is appropriate for making recordings from up to 8 pairs of differential electrodes.  The D440, which operates in AC or DC modes, is available in 2 (D440-2) or 4 channel (D440-4) versions and is currently only certified for human research applications.

The D175 Electrode Impedance Meter permits checking of electrode impedances, while our D179 Performance Checker can be used in conjunction with a calibrated signal generator to confirm that the your amplifier gains are within specification.  We also provide an Audio Interface and Serial to USB Adaptor for our D360 amplifier.
