16 Claims

1. A surgical insertion system for identifying a trauma response, the system comprising:

an insertion tool configured for inserting an electrode array into a patient cochlea, wherein the electrode array includes a plurality of electrode contacts distributed along an outer surface, the plurality electrode contacts including at least one first electrode contact and at least one electrode contact; and

an insertion controller, configured to control the inserting of the electrode array by the insertion tool, including at least one hardware processor executing program instructions for:

determining at least one measurement difference value for the at least one first electrode contact located at a given insertion depth into the patient cochlea during insertion of the electrode array based on comparing stimulus response data for the at least one first electrode contact at the given insertion depth to stimulus response data for the at least one second electrode contact when the at least one second electrode contact was located at the given insertion depth during the insertion of the electrode array, and

identifying a potential trauma response when the at least one measurement difference value exceeds a defined difference value.
