This invention concerns imageable, radiopaque embolic beads, which are particularly useful for monitoring embolization procedures. The beads comprise iodine containing compounds which are covalently incorporated into the polymer network of a preformed hydrogel bead. The beads are prepared by activating pre-formed hydrogel beads towards nucleophilic attack and then covalently attaching iodinated compounds into the polymer network. The radiopaque beads may be loaded with chemotherapeutic agents and used in methods of embolizing hyperplastic tissue or solid tumors.

Disclosed herein are novel procedures, systems and excipient solutions for in situ provision of a contrast media at a user defined concentrations. An automated procedure according to embodiments of the current invention provides increased user safety, flexibility and user friendliness.

This invention relates to imageable polymers, particularly those comprising poly vinylalcohol and to methods for making them as well as to embolic microspheres comprising the polymers. The microspheres are imageable during embolization procedures and can be loaded with drugs or other therapeutic agents to provide an imageable drug delivery system.
