The OCS2PND is a bipolar stimulating probe for cortical stimulation with malleab
The OCS2PND is a bipolar stimulating probe for cortical stimulation with malleable tips for precise localization. The probe has 2 mm diameter polished balls, spaced 5 mm apart, at the tip of the stimulator probe. It has a 310 cm cord with two electrically shrouded banana plugs for attachment to the OCS2 Ojemann Cortical Stimulator. It is reusable, is supplied non-sterile and must be sterilized before use.
The AURAGEN™ Cortical Surface Electrodes are designed for intraoperative monitor
The AURAGEN™ Cortical Surface Electrodes are designed for intraoperative monitoring of cortical electrical activity in order to define the location of epileptogenic foci. They are placed on the exposed cortical surface or inserted into the subdural space to contact the cortical surface. Cortical Electrodes are available with platinum contacts and vary in size according to the number of contacts. The type of cortical electrode used is dependent on the procedure and the size of area being tested.
