Abstract
A downhole tool with a swellable mantle is configured for insertion of a cable into a longitudinal slit in the mantle. An arcuate groove is formed in an outer surface of the mantle corresponding to a displacement caused by the inserted cable, so that the displacement is counteracted and the outer surface of the mantle remains smooth.
