Subcutaneous biopsy cavity marker device
View Patent ↗A marking device for identifying a subcutaneous biopsy cavity having a first nonabsorbable marker element detectable by a first imaging modality and a second nonabsorbable marker element detectable by a second imaging modality but not detectable by the first imaging modality.
1. A breast biopsy marker comprising:
a first marker element;
a second marker element having an outer surface;
the first marker element formed from a nonabsorbable metallic material detectable by an imaging means other than ultrasound;
the second marker element formed from a nonabsorbable polymer detectable by ultrasound; and
the first marker element is disposed around and contacts a portion of the outer surface of the second marker element.
2. The breast biopsy marker according to claim 1 , herein the first marker element is made from shaped-titanium.
3. The breast biopsy marker according to claim 1 , wherein the first marker element is detectable by magnetic resonance imaging.
4. The breast biopsy marker according to claim 1 , wherein the first marker element is radiopaque.
5. The breast biopsy marker according to claim 1 , wherein the second marker element is layered.
6. The breast biopsy marker according to claim 1 , wherein the second marker element is rolled.
7. The breast biopsy marker according to claim 1 , wherein the second marker element is a diecut polymer material.
8. A breast biopsy marker consisting of:
a first marker element;
a second marker element;
the first marker element formed from a nonabsorbable metallic material detectable by an imaging means other than ultrasound;
the second marker element formed from a nonabsorbable polymer detectable by ultrasound; and
the first marker element is disposed around a portion of the second marker element.
9. The breast biopsy marker according to claim 8 , wherein the first marker element is made from shaped titanium.
10. The breast biopsy marker according to claim 8 , wherein, the first marker element is detectable by magnetic, resonance imaging.
11. The breast biopsy marker according to claim 8 wherein the first marker element is radiopaque.
12. The breast biopsy marker according to claim 8 , wherein the second marker element is layered.
13. The breast biopsy marker according to claim 8 wherein the second marker element is rolled.
