A solution for forming a marker or filler mass for an intracorporeal site. The solution contains a polar, water soluble non-aqueous solvent such as dimethyl sulfoxide and a bioabsorbable, essentially water insoluble polymer such as polylactic acid, or copolymers of lactic acid and glycolic acid. The solution may be delivered to the biopsy site by a suitable syringe and delivery tube. The delivery tube is preferably provided with a releasable radiopaque element on the distal tip which can be released within the polymeric marker mass formed in the biopsy cavity. |
