1. A method for localizing a target site in solid tissue, said method comprising:
- percutaneously introducing an illumination source through solid tissue to the target site in the solid tissue;
emitting illumination from the illumination source into the tissue; and
detecting the emitted illumination to mark the target site.

Abstract
Lesions, biopsy sites, and other target sites in solid tissue are localized by positioning an illumination source adjacent the lesion in the solid tissue. Usually, the illumination source is positioned using a localization wire which is percutaneously introduced to the lesion. Alternatively, the illumination source may be provided by an implantable capsule which is introduced using a cannula or needle. In both cases, the illumination may be visually or optically detected and used to guide a surgical procedure to the lesion. Kits comprising the localization wire illumination capsule, and instructions for use are also described.

23. A method for localizing a biopsy site, said method comprising the steps of percutaneously removing tissue from a target site;
- and placing a detectable marker that emits illumination at or near the site from which tissue was removed.

24. A method for localizing a biopsy site, said method comprising the steps of percutaneously removing tissue from a target site;
- placing a detectable marker at or near the site from which tissue was removed, said detectable marker comprising a power source at an illumination source that emits illumination that can be detected, analyzing the removed tissue to determine if further removal of tissue is necessary, and when further removal is necessary, said method further comprising the steps of selectively activating the illumination and power sources, detecting the detectable marker and removing additional tissue in the region of the marker.
