Abstract
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.
