<p>A downhole tool accommodates a feed-through line running along a tubing string. The tool has a mandrel and a sleeve disposed on the mandrel. The feed-through line runs adjacent the mandrel and can be accommodated in a groove defined in an inner dimension of the sleeve. When deployed and compressed, the sleeve is compressible from an uncompressed state to a compressed state in which the sleeve expands radially outward to seal in casing or borehole. The sleeve defines a radial spiral slit along a length of the sleeve and wraps around the mandrel and the feed-through line. External spacing of the radial slit on an exterior of the sleeve can vary along the length of the sleeve, and a cross-sectional angle of the radial slit from an interior to an exterior of the sleeve can vary along the length of the sleeve.</p> |
