Abstract

In order to later identify the location of a biopsy or surgery, various means and methods for permanently and non-surgically marking selected tissue in the human body are used. Later visualization of the markers is readily accomplished using state-of-the-art imaging systems.

Claims

1. A breast biopsy marking system comprising:

a delivery tube in the form of an elongated lumen; and

a plurality of marker elements preloaded into the delivery tube;

wherein at least one of the marker elements includes a radiopaque wire segment.

2. The device of claim 1 wherein at least one of the marker elements is non-metallic.

3. The device of claim 1 wherein at least one of the marker elements is metallic.

4. A breast biopsy marking system comprising:

a delivery tube in the form of an elongated lumen; and

three or more marker elements preloaded into the delivery tube;

wherein at least one of the marker elements includes a radiopaque wire segment.

5. The device of claim 4 wherein at least one of the marker elements is non-metallic.

6. The device of claim 4 wherein at least one of the marker elements is metallic.

7. A breast biopsy marking system comprising:

a delivery tube in the form of an elongated lumen; and

a plurality of marker elements preloaded into the delivery tube;

wherein at least one of the marker elements includes a stored energy and expands upon exiting the delivery tube.

8. The device of claim 7 wherein at least one of the marker elements is non-metallic.

9. The device of claim 7 wherein at least one of the marker elements is metallic.
