Claim:
1. A cable duct device, comprising: a swellable packer, the packer including a seal material which swells and thereby increases in volume in response to contact with a swell-activating material, wherein the packer is not radially expanded by mechanical compression of the seal material; at least one through-going opening extending generally longitudinally through the seal material, wherein the through-going opening is positioned between an inner surface of the packer and an outer surface of the packer, wherein the through-going opening includes a bend, and wherein a length of the through-going opening is substantially greater than a width of the through-going opening; and a slit extending between the through-going opening and only one of the outer surface of the packer and the inner surface of the packer, wherein the slit comprises first and second opposing surfaces which are radially separated during insertion of a cable into the through-going opening via the slit, wherein a length of the cable inserted into the through-going opening is greater than a longitudinal length of the packer, and wherein seals are formed between the first and second opposing surfaces of the slit, between the cable and an interior surface of the through-going opening, and between the outer surface of the packer and a surrounding well surface in response to swelling of the seal material.
