    摘要： Systems and methods are provided for identifying or locating a tag within a patient's body that include a probe that transmits synchronized electromagnetic signals, e.g., RF energy, and optical signals, e.g., infrared light pulses into the patient's body, whereupon the tag converts the optical signals into electrical energy to open and close a switch in the tag to modulate signals, e.g., backscatter signals, transmitted by the tag in response to the electromagnetic signals. For example, the tag may include photodiodes coupled to the switch that transforms the optical signals to alternately short the antenna to modulate the backscatter signals. Alternatively, the tag may include a smart circuit that harvests electrical energy from the optical signals to power the smart circuit and/or modulate the backscatter signals, e.g., to include data related to the tag and/or alternate the tag between an information mode and a distance mode.

    摘要： Markers, microwave probes, and related systems and methods are provided for localizing lesions within a patient's body, e.g., within a breast. The marker includes an energy converter e.g., one or more photodiodes, for transforming energy pulses striking the marker into electrical energy, a switch, e.g., FET, coupled to the photodiodes such that light from a probe cause the switch to open and close. A pair of antenna wires are coupled to the switch to provide an antenna, the switch configured to open and close when light strikes the photodiodes to modulate signals from the probe reflected by the antenna back to the probe to identify the location of the marker. The marker also includes an electro static discharge (ESD) protection device coupled to the switch to provide protection against an electrostatic discharge event.

    摘要： Apparatus for delivering brachytherapy to a target tissue region includes an elongate body including a proximal end, a distal end sized for introduction into a tissue tract and carrying a plurality of elongate members including pathways for receiving a source of radiation. The elongate members are movable between collapsed and expanded configurations. During use, a tract is created through tissue, and the elongate body carrying the elongate members is advanced through the tract into a target location with the elongate members in the collapsed configuration. The elongate members are directed to the expanded configuration at the target location, and radiation is delivered to treat tissue at the target location, e.g., by introducing one or more radiation sources along the pathways.

    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.
