Abstract:
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

Claim (Index 38):
Hydrogel polymer microspheres wherein the hydrogel polymer comprises: a polyvinyl alcohol (PVA) backbone comprising at least two pendant chains having cross-linkable ethylenically unsaturated functional groups which are cross linked by a vinylic co-monomer;\n the PVA backbone further comprising 1,3-diol groups acetalised with a radiopaque species which is coupled to the hydrogel polymer through a cyclic acetal group, the radiopaque species comprising one or more covalently bound iodines.
