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.
Claims16
A system comprising:
- a remote activating device that generates a magnetic field;
- wherein said remote activating device comprises a pad configured to be positioned:
- i) on or under a patient, or ii) on or under a table or bed said patient is on, wherein said pad comprises multiple activating coils;
- a first wireless tag that is insertable at a location in or on a tissue of said patient, wherein said first wireless tag is activated by said magnetic field;
- a second wireless tag coupled to a surgical instrument;
- wherein the second wireless tag is activated by said magnetic field;
- a control unit comprising a processor and a control software, wherein said control unit is linked to said remote activating device;
- and
- a display component configured to provide a distance of the surgical instrument to a user-defined boundary around said first wireless tag;
- wherein said display component is removably mounted to said surgical instrument.

A method for localizing a tissue region of a patient, comprising:
- placing a remote activating device and a patient in proximity to each other, wherein said remote activating device comprises a pad with multiple activating coils that generate a magnetic field, and wherein said patient comprises a first wireless tag at a location in, on, or proximal to a tissue of said patient;
- positioning a surgical instrument with a second wireless tag in proximity to said tissue of said patient such that said patient is between said surgical instrument and said pad;
- localizing said first wireless tag in said patient and said second wireless tag by generating a magnetic field with said remote activating device and detecting a signal;
- and
- displaying, on a display component, a distance of the surgical instrument to a user-defined boundary around said first wireless tag;
- wherein said display component is removably mounted to said surgical instrument.
