Abstract
An improved deformable carrier or connector for an implantable neural interface device is described. The neural interface device comprises a carrier supporting at least one electrode array. The carrier comprises a tubular sidewall extending from a proximal carrier portion to a distal carrier portion. At least one deformable segment is provided in the carrier sidewall. The deformable segment is more pliable than the remainder of the carrier sidewall to preferably move in response to forces imparted on the carrier and the electrode array by the shifting forces in body tissue. The deformable segment takes the form of a thinned sidewall segment or a slitted wall segment.
