D185 MultiPulse Cortical Stimulator

Now used worldwide as an effective tool for intraoperative monitoring of the spinal cord, the D185 is the ONLY standalone stimulator with FDA clearance for this application.  The D185 allows transcranial motor evoked potentials (MEPs) to be used in surgical procedures such as scoliosis correction, spinal tumour resection and thoraco-abdominal aortic aneurysm (TAAA) repair.  The 1000V power source means that MEPs can even be evoked in patients with pre-existing neuropathologies.  Recent design enhancements facilitate (external) control of the trigger settings, making it easier to interface the D185 with various EMG systems.  In addition, customer feedback has prompted the inclusion of an added polarity reversal feature.

Alternative Application:  The brief high voltage output also makes the D185 suitable for nerve root stimulation during differential diagnosis of peripheral nerve disorders such as multifocal motor neuropathy and motor neuron disease.  Please refer to the Peripheral Stimulators section for further details on this application.

Major Features Include:

- 1000V maximum voltage output (set by user).

- 1.5A maximum current output (LCD monitor).

- Risetime of 0.1A per microsecond.

- 50µs pulse duration.

- 1 to 9 pulses with user defined interpulse interval.

- Reversible output polarity switch.

- User defined trigger facilities permit integration with popular EMG recording equipment.
