Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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. 14. The breast biopsy marker according to claim 8 , wherein the second marker element is a diecut polymer material. 15. The breast biopsy marker according to claim 8 , wherein the second marker has first and second ends, and wherein the first marker element is disposed around and contacts a portion of the outer surface spaced from the first and second ends. 16. The breast biopsy marker according to claim 1 , wherein the second marker has first and second ends, and wherein the first marker element is disposed around and contacts a portion of the outer surface spaced from the first and second ends. 17. The breast biopsy marker according to claim 8 , wherein the first marker element is a ring. 18. The breast biopsy marker according to claim 1 , wherein the first marker element is a ring. 19. The breast biopsy marker according to claim 12 , wherein the second marker element is fastened together by the first marker element. 20. The breast biopsy marker according to claim 13 , wherein the second marker element is secured together by the first marker element. 21. The breast biopsy marker according to claim 5 , wherein the second marker element is fastened together by the first marker element. 22. The breast biopsy marker according to claim 6 , wherein the second marker element is secured together by the first marker element.
