Subcutaneous cavity marking device and method
First Claim
1. A biopsy marking device comprising:
- a cylindrical body having an exterior surface and a central longitudinal axis, the body comprising a polymer;
at least one echogenic marker arranged along the central longitudinal axis;
wherein the body includes at least one hollow pore extending through the body at an angle to the central longitudinal axis,wherein the at least one pore has an opening at the exterior surface of the body; and
wherein the body is echogenic.

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.
