Subcutaneous cavity marking device and method
DCFirst Claim
1. A subcutaneous cavity marking device comprising:
- (a) at least one filler body comprising a resilient bioabsorbable material, and (b) at least one detectable marker attached to said filler body and adapted to mark a center of said filler body, wherein said marker is mammographic.

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.

84. A method of marking a tissue cavity having a margin in a mammalian body, comprising:
-
(a) subcutaneously accessing the cavity via a delivery device, (b) introducing a biocompatible liquid in a remotely-detectable marker having a predetermined shape; and
thereafter(c) deploying the marker through the delivery device into the cavity, wherein upon delivery into the cavity the marker assumes a predetermined three-dimensional configuration so to (1) substantially fill the cavity, (2) mark the cavity margin, and (3) indicate the orientation of the marker inside the cavity. - View Dependent Claims (85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97)
