Apparatus, systems, and methods for localizing markers or tissue structures within a body
First Claim
1. A system for localization of a target tissue region within a patient'"'"'s body, comprising:
- a probe comprising a substantially flat patient contact surface and one or more antennas for transmitting electromagnetic signals into a patient'"'"'s body and receiving reflected signals from the patient'"'"'s body, through the patient contact surface, the probe analyzing the reflected signals to identify one or more objects within the patient'"'"'s body; and
a marker sized and configured for implantation directly in tissue within a patient'"'"'s body independent of a delivery device used to deliver the marker;
the marker comprising an active reflector to enhance identification of the marker by the probe.

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.

15. A system for localization of a target tissue region within a patient'"'"'s body, comprising:
-
a probe comprising a patient contact surface for placement against a patient'"'"'s skin and one or more antennas for transmitting micro-impulse radar signals into a patient'"'"'s body and receiving reflected signals from the patient'"'"'s body through the patient contact surface, the probe analyzing the reflected signals to identify one or more objects within the patient'"'"'s body; and a marker sized for implantation in tissue within a patient'"'"'s body, the marker comprising a core member biased to a curvilinear shape for deployment within tissue and resiliently flexible to be straightened to a linear shape for loading into a delivery device, the marker comprising one or more elements to enhance identification of the marker by the probe. - View Dependent Claims (16, 17)

18. A system for localization of a target tissue region within a patient'"'"'s body, comprising:
-
a delivery device comprising a shaft including a proximal end and a sharpened distal end sized for percutaneous introduction through tissue within a patient'"'"'s body into a target tissue region, the delivery device carrying one or more markers implantable in tissue within or around the target tissue region and including a pusher member for deploying the one or more markers from the delivery device; and a probe comprising one or more antennas for transmitting and receiving micro-impulse radar signals to detect the one or more markers implanted within or around the target tissue region when the probe is placed adjacent the target tissue region. - View Dependent Claims (19, 20, 21)

22. A system for localization of a target tissue region within a patient'"'"'s body, comprising:
-
a marker comprising an elongate core member and a plurality of beads coupled to the core member, the beads comprising a plurality of surfaces and edges at least partially defining outer surfaces of the marker to enhance reflection of electromagnetic signals to facilitate identification of the marker; and a probe comprising one or more antennas for transmitting electromagnetic signals into a patient'"'"'s body and receiving reflected signals from the patient'"'"'s body, the probe analyzing the reflected signals to identify the marker after being implanted within the patient'"'"'s body. - View Dependent Claims (23, 24, 25, 26)
