D185 MKII

Multipulsation stimulator

The D185 is a constant voltage stimulator, specially designed for the evoked potential method which aims to measure the electrical activity of the nerve pathways of hearing, vision, sensitivity and motor skills in a surgical environment. .
An effective tool for intraoperative spinal cord monitoring, the D185 MKII is the ONLY autonomous pacemaker with FDA clearance for this application. The D185 MKII enables the use of transcranial motor evoked potentials (TPEs) in surgical procedures such as:

• Correction of scoliosis
• Resection of the vertebral tumor
• Repair of the thoraco-abdominal aortic aneurysm (TAAA)…

The 1000 V power source means that PEMs can even be evoked in patients with pre-existing neuropathologies. Recent design enhancements make it easier to (externally) control trigger parameters, making it easier to interface the D185 MKII with various EMG (Electromyogram) systems
