An implantable connector used with a neurological device and a lead
extension includes a male connector having a plurality of electrical
contacts axially arranged along the connector, insulated from each other.
The connector also includes a female connector having channels axially
disposed therein and a plurality of conductors axially arranged on the
female connector. The plurality of conductors are electrically insulated
from each other, and at least one indexing element is adjacent the
channels. The indexing element allows receipt of the male connector by
the channels in a defined orientation relative to the channels, thereby
forming at least two electrical connections along two or more axial
positions. Often the neurological device is a brain stimulating and
recording lead. The male and female connectors are often fastened
together with a screw or by twist-locking the two together.
