Apparatus, systems, and methods for localizing markers or tissue structures within a body

摘要

Apparatus, systems, and methods are provided for localizing lesions within a patient's body, e.g., within a breast. The system may include one or more markers implantable within or around the target tissue region, and a probe for transmitting and receiving electromagnetic signals to detect the one or more markers. During use, the marker(s) are into a target tissue region, and the probe is placed against the patient's skin to detect and localize the marker(s). A tissue specimen, including the lesion and the marker(s), is then removed from the target tissue region based at least in part on the localization information from the probe.

1. A method for localizing a target tissue region within a patient's body, comprising:
implanting a target in the target tissue region within a breast of the patient's body, the target comprising a single core member having a first wire end and a second wire end generally opposite the first wire end, and an electronic circuit carried by the core member configured to provide an active reflector antenna; and placing a probe adjacent the target tissue region, the probe transmitting micro-impulse radar signals towards the target tissue region, receiving signals reflected from the target, and displaying spatial information to provide a spatial relationship between the target and the probe based on the reflected signals, the spatial relationship comprising a distance from the probe to the target; wherein the electronic circuit modulates signals from the probe that strike the target such that the signals reflected from the target enhance identification of the target by the probe.
