  • Patent number: 11963753
    Abstract: 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.

  • Publication number: 20230028061
    Abstract: Apparatus, systems, and methods are provided for localization of a needle within a patient's body using markers. In an exemplary embodiment, a probe includes a distal end for placement against a surface of the region and one or more antennas for transmitting electromagnetic signals into and receiving reflected signals from the region. A processor processes the modulated reflected signals at one or more of the surface locations to determine marker locations along the needle and generate a three-dimensional model of the body region and needle.

  • Patent number: 11298045
    Abstract: Apparatus, systems, and methods are provided for localizing lesions within a patient's body, e.g., within a breast. The system includes a microwave antenna probe for transmitting and receiving electromagnetic signals to detect one or more markers that are implanted within or around the target tissue region. During use, the marker(s) are implanted into a target tissue region, and the microwave antenna probe is placed against the patient's skin to transmit a signal to the marker(s) and to receive the reflected signal from the marker(s) in order to determine the location of 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 location information from the microwave antenna probe.

  • Patent number: 11130004
    Abstract: 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.

  • Patent number: 9067063
    Abstract: Brachytherapy treatment apparatus are provided that include an elongate core member, a plurality of expandable catheters or other elongate members and a balloon or other expandable member on a distal portion adjacent the core member. Each catheter includes a distal end coupled to the core member distal end, a proximal end movable relative to the core member, and a lumen extending between the proximal and distal ends for receiving a source of radiation therealong. The balloon is expandable independently of the catheters such that the balloon may be expanded after expanding the catheters, e.g., to facilitate imaging and/or dose planning. Optionally, a working channel may be provided for receiving an aspiration catheter or other instrument or at least one of the catheters may include an aspiration lumen and one or more ports, e.g., for aspirating material from a region surrounding the distal portion.
