Abstract
A probe sheath and probe wire having a memory hook and soft flexibility are used to locate a small presymptomatic breast lesion, wherein the wire is sheathed within the sheathing cannula and both are inserted into the body tissue and directed to the site of the lesion. Thereafter the wire is extended through the sheath to assume its memory configuration and its location is determined mammographically. If re-positioning is necessary the wire may be retracted into the sheath and then extended and re-anchored after the wire and sheath are directed to a new position. When the probe wire location is acceptable the cannula is removed and the probe wire is left as a marker for surgical excision of the lesion.
