Abstract: A polymer is dissolved in a first liquid or the polymer is brought into the liquid phase. To the solution are added particles which are insoluble in the first liquid, so that a suspension or dispersion results. The suspension or dispersion is then transferred into an excess of second liquid, in which both the polymer and the particles are insoluble. The second liquid is mixed vigorously and this results in a precipitate of the polymer with the particles encapsulated therein.

Abstract: Porous polymers having a plurality of openings or chambers that are highly convoluted, with each chamber being defined by multiple, thin, flat partitions are produced by a new gel enhanced phase separation technique. In a preferred embodiment, a second solvent is added to a polymer solution, the second solvent causing the solution to gel. The gel can then be shaped as needed. Subsequent solvent extraction leaves the porous polymeric body of defined shape. The porous polymers have utility as medical prostheses, the porosity permitting ingrowth of neighboring tissue. The present technique also enhances shape-making capability, for example, of bifurcated vascular grafts, which feature a common entrance region but two or more exit regions.

Abstract: The present invention relates generally to a polyvinyl acetate (PVA) sponge. More specifically, a PVA sponge according to the present invention has certain improved physical characteristics, such as uniform pore size, a microscopically rough surface, and/or a neutral surface charge. Certain characteristics may be achieved by a variety of methods in which pore-forming chemicals are dissolved into a PVA solution, so that no solid residues remain in the pores of a PVA sponge after production. Neutral surface charge of a PVA sponge may be achieved by adding a charge modifying agent during the sponge making process.
