This invention is a tissue modification apparatus, method for accurately marking, and locating a lesion or other suspect tissue. More particularly, a tissue modification device (2300) such as a surgical cutter (2340) adapted with at least one proximity sensor (2380) for detecting the location, distance of a remotely detectable marker (2100), and a method for using the same, is disclosed. This invention also variously comprises a remotely detectable marker (2100), a control system (2600), a computer-readable medium, and feedback apparatus (2700) such as a visual display (2390). In operation, once the remotely detectable marker is deployed in the tissue of interest, the tissue modification device is used to modify tissue while determining the instantaneous location of the marker in space, and the instantaneous distance of the marker relative to a sensor (2380) to guide the cutting device (2340) to the marker (2100). |
