Abstract
A lead engagement device is configured to be positioned in a lead lumen. The lead engagement device includes a hypotube. The hypotube includes a wall having an inner surface defining an inner lumen and an outer surface. The wall defines a longitudinal axis of the hypotube. A plurality of lead engagement fingers extend outwardly and proximally from the outer surface at acute angles, and planes in which the acute angles are disposed extend diagonally relative to the longitudinal axis. The plurality of lead engagement fingers are configured to translate relative to the lead and permit relative motion between the lead engagement device and the lead when applying a first force to the lead engagement device. The plurality of lead engagement fingers are configured to engage the lead and inhibit relative motion between the lead engagement device and the lead when applying an opposite second force to the lead engagement device.
