Abstract
Provided herein are systems and methods comprising two or more localization agents that are linked together by a linker. For example, provided herein are systems and methods for the placement of two or more linked localization devices within biological systems and the detection of such localization devices for targeted surgeries or other medical procedures. For example, provided herein are systems comprising one or more miniature detectable devices that are linked together, that are placed into a target location and activated by remote introduction of a magnetic field.
Claims40
A system comprising:
- a) at least two tags;
- b) a linker attached to said at least two tags;
- wherein the linker includes a grip that is graspable by a surgical tool;
- c) a remote activating device that generates a magnetic field within a region of each tag;
- and
- d) a plurality of sensors configured to detect a signal from each tag while each tag is exposed to said magnetic field.
A system comprising:
- a) at least two tags;
- b) a linker attached to said at least two tags;
- c) a remote activating device that generates a magnetic field within a region of each tag;
- d) a plurality of sensors configured to detect a signal from each tag while each tag is exposed to said magnetic field;
- and
- e) a wire or line, wherein said wire or line is attached to, and/or passes through, said linker at two or more points on said linker.
A system comprising:
- a) at least two tags;
- wherein the at least two tags comprise a non-dielectric resonant antenna capacitor;
- b) a linker attached to said at least two tags;
- c) a remote activating device that generates a magnetic field within a region of each tag;
- and
- d) a plurality of sensors configured to detect a signal from each tag while each tag is exposed to said magnetic field.
A system comprising:
- a) at least two tags;
- b) a linker attached to said at least two tags;
- wherein the linker comprises a torsion spring;
- c) a remote activating device that generates a magnetic field within a region of each tag;
- and
- d) a plurality of sensors configured to detect a signal from each tag while each tag is exposed to said magnetic field.
A system comprising:
- a) at least two tags;
- b) a linker attached to said at least two tags;
- wherein said linker is configured to hold said at least two tags in a position when present in tissue, wherein at least one of said at least two tags in said position points approximately in the X dimension, and at least one of said at least two tags points approximately in the Y dimension;
- c) a remote activating device that generates a magnetic field within a region of each tag;
- and
- d) a plurality of sensors configured to detect a signal from each tag while each tag is exposed to said magnetic field.
A system comprising:
- a) at least three tags comprising a first tag, a second tag, and a third tag;
- b) a linker attached to the at least three tags;
- and wherein when present in tissue:
- i) said first tag points approximately in the X dimension, ii) said second tag points in approximately the Y dimension, and iii) and said third tag points in approximately in the Z dimension;
- c) a remote activating device that generates a magnetic field within a region of each tag;
- and
- d) a plurality of sensors configured to detect a signal from each tag while each tag is exposed to said magnetic field.
A system comprising:
- a) at least two tags;
- b) a linker attached to said at least two tags;
- wherein the linker comprises a shape-memory alloy;
- c) a remote activating device that generates a magnetic field within a region of each tag;
- and
- d) a plurality of sensors configured to detect a signal from each tag while each tag is exposed to said magnetic field.
