Fibrous marker and intracorporeal delivery thereof

An intracorporeal marker comprising a fibrous unitary marker body configured as a roll of bioabsorbable fiber material having at least one wrap.

The intracorporeal marker of claim 16, comprising a core of compressed bioabsorbable fibers bound in the compressed configuration by a polymer binding agent, the core being interposed within the roll of bioabsorbable fiber material.

An intracorporeal marker delivery device, comprising:

• a delivery cannula which has a distal tip, an inner lumen and a discharge opening in communication with the inner lumen;
• and
• a fibrous unitary marker body comprising bioabsorbable fibers which is compressed into a compressed configuration and bound in the compressed configuration by a binding agent prior to insertion into the inner lumen of the delivery cannula, the fibrous unitary marker body being slidably disposed within and pushable through the inner lumen of the elongated delivery cannula proximal to the discharge opening.
