It was found that insertion of these structures into cortical tissues could only be performed using high insertion speeds. A pneumatically actuated impact insertion system has been developed that is capable of inserting an electrode array into feline brain tissue at speeds from about 1 to 11 m/s. We found that a minimum array insertion speed of 8.3 m/s was necessary for a complete, safe insertion of all 100 electrodes in the array to a depth of 1.5 mm into feline cortex. The performance of the impact insertion system is discussed in terms of a simplified representation of cortical tissue.
