Subcutaneous cavity marking device
DCFirst Claim
1. A subcutaneous cavity marking device percutaneously implantable in breast tissue during a biopsy procedure comprising:
- at least two implantable bodies, one made from a first material and another made from a second material wherein the first and second materials are different materials and the at least two implantable bodies are adapted to be inserted into a subcutaneous cavity created by removal of tissue, wherein the at least two implantable bodies are detectable via non-invasive techniques as tissue cavity markers; and
at least one of the at least two detectable bodies has a distinguishing pattern and is disposed within the other of the at least two implantable bodies wherein the other of the at least two implantable bodies is bioabsorbable.

Abstract
These are subcutaneous 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 cavity by radiographic, mammographic, echogenic, or other non-invasive imaging techniques. Also, the device contains a bioabsorbable or non-bioabsorbable 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 subcutaneous cavity using a bioabsorbable material and a bioabsorbable or non-bioabsorbable marker in conjunction with the material. The method also may combine any of the features as described with the device.
