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 a detection component that is attached to or integrated with a surgical device, where the detection component detects a signal from a tag in a patient, where the tag is activated by remote introduction of a magnetic field.

Claims

1. A method for detecting and processing a signal from an RFID tag in a patient, comprising:

a) placing a remote activating device and a patient in proximity to each other,

wherein said remote activating device comprises a pad, wherein said pad comprises an excitation coil that generates a magnetic field, and

wherein said patient comprises an RFID tag at a location in, on, or proximal to a target tumor of said patient;

b) detecting a signal from said RFID tag in said patient by generating a magnetic field with said remote activating device,

c) processing, with a control unit, said signal from said RFID tag to generate distance-to-tag and orientation data for an electrocautery device,

wherein said RFID tag is not attached to said electrocautery device,

wherein said control unit comprises;

a processor and control software, and

wherein said electrocautery device comprises an electrode tip, and

d) displaying, with a display component, the distance of said electrode tip to said RFID tag and the pitch and yaw of said electrocautery device.

2. The method of claim 1, wherein said pad is placed under said patient.

3. The method of claim 1, wherein said display component comprises a visual, audible, or sensory display.

4-7. -7. (canceled)

8. A system comprising:

a) an electrocautery device comprising an electrode tip,

b) a remote activating device that generates a magnetic field, wherein said remote activating device comprises a pad, and wherein said pad comprises an excitation coil;

c) an RFID tag that is insertable at a location in or on a tissue of a patient, wherein said RFID tag is not attached to said electrocautery device,

d) a display component that reports;

i) the distance of said device electrode tip to said RFID tag, and the pitch and yaw of said electrocautery device, and

e) a control unit comprising a processor and a control software, wherein said control unit, provides distance-to-tag and orientation data to said display component.

9. The system of claim 8, wherein said pad is configured to be placed under said patient.

10. The system of claim 8, wherein said display component comprises a visual, audible, or sensory display.
