Abstract
Provided herein are systems, devices, assemblies, and methods for localization of a tag in a tissue of a patient. For example, provided herein are systems, devices, and methods employing an implantable tag that emits sidebands at defined frequencies upon activation by a magnetic field generated by a remote activating device, and a plurality of witness stations configured to detect such sidebands. Also provided herein are herein are systems, devices, and methods employing a detection component that is attached to or integrated with a surgical device.
Claims23
A system comprising:
- a) a tag, said tag comprising a radio-frequency identification (RFID) chip and an antenna, wherein said tag emits a sideband at a defined frequency, upon activation by a magnetic field;
- b) a remote activation device that generates a magnetic field within a region of the tag;
- c) a plurality of witness stations, each said witness station comprising an antenna configured to detect said sideband,
- d) a lock-in amplifier tuned to said defined frequency of said sideband;
- and
- e) a component that is attachable to a medical device, wherein said component comprises:
- i) at least two medical device location emitters, and
- ii) an indicator comprising a visual display that presents distance to tag information, and spatial orientation, for said medical device.
