an intracorporeal marker includes a fibrous unitary marker body having bioabsorbable fibers compressed into a compressed configuration , and bound in the compressed configuration by a polymer binding agent . the intracorporeal marker may be incorporated into an intracorporeal marker delivery device having a delivery cannula which has a distal tip , an inner lumen and a discharge opening in communication with the inner lumen . the compression and binding occur prior to insertion of the fibrous unitary marker body into the inner lumen of the delivery cannula . the fibrous unitary marker body is slidably disposed within and pushable through the inner lumen of the elongated delivery cannula proximal to the discharge opening .
