These are biopsy cavity marking devices and methods. More particularly, upon insertion into a body, the cavity marking device and method enable one to determine the center, orientation, and periphery of the biopsy cavity by radiographic, mammographic, echogenic, or other non-invasive imaging techniques. Also, the device contains a detectable marker. The device may be combined with various substances enhancing the radiopaque, mammographic, or echogenic characteristics of the marker or the body allowing it to be observed by any non-invasive imaging techniques. This is further a method of marking a biopsy cavity using a bioabsorbable material and a detectable marker in conjunction with the material. The method also may combine any of the features as described with the device.

1. A method of marking a biopsy cavity, comprising the steps of: accessing the biopsy cavity with a delivery device; anddeploying a bioabsorbable filler body through the delivery device, wherein the bioabsorbable filler body matches a shape of the biopsy cavity and has a detectable marker attached thereto, and wherein the detectable marker is placed in substantially a center of the biopsy cavity. 2. The method of claim 1, further comprising the step of determining the location of the biopsy cavity by detecting the location of the detectable marker. 3. The method of claim 1, wherein the detectable marker is mammographic. 4. The method of claim 1, wherein the detectable marker is radiopaque. 5. The method of claim 1, wherein the detectable marker is echogenic. 6. The method of claim 1, wherein the detectable marker is palpable. 7. The method of claim 1, wherein the detectable marker is adapted to mark a center of the bioabsorbable filler body. 8. The method of claim 7, wherein the detectable marker is substantially located at a geometric center of the bioabsorbable filler body. 9. The method of claim 1, wherein the detectable marker is a ring. 10. The method of claim 1, wherein the detectable marker is a wire. 11. The method of claim 1, wherein the detectable marker is a band. 12. The method of claim 1, wherein the detectable marker is affixed to an interior of the bioabsorbable filler body. 13. The method of claim 1, wherein the detectable marker is affixed to an exterior surface of the bioabsorbable filler body. 14. The method of claim 1, wherein the detectable marker is suspended in an interior of the bioabsorbable filler body. 15. The method of claim 1, wherein the bioabsorbable filler body comprises collagen. 16. The method of claim 1, wherein the bioabsorbable filler body comprises cellulose. 17. The method of claim 1, wherein the bioabsorbable filler body comprises polyglycolic acid. 18. The method of claim 1, wherein the bioabsorbable filler body comprises polylactic acid. 19. The method of claim 1, wherein the bioabsorbable filler body comprises copolymers of polyglycolic acid and polylactic acid. 20. The method of claim 1, wherein the bioabsorbable filler body comprises at least one bioabsorbable filler body. 21. The method of claim 1, wherein the detectable marker comprises at least one detectable marker.
