Abstract
A cochlear electrode comprising a spirally curved distal tip portion carrying electrical conductors for stimulating the cochlea, a lead offset from the distal tip portion and a bridge therebetween and extending from the distal tip adjacent the proximal terminus thereof. The bridge defines a slide for guiding the distal tip portion into and out of an insertion tool during implantation of the electrode while the proximal terminus defines a push point for a push rod included in the insertion tool for sliding the distal tip out of the tool and into the cochlea.
