Another article may include at least one layer of foam, the foam having pores of different sizes, at least some of the pores at least partially filled with at least one elutable antimicrobial agent, the pores of different sizes forming a gradient with the foam layer. Yet another article may include a foam matrix and a plurality of dissolvable members disposed with the foam matrix, at least one antimicrobial agents associated with the dissolvable members such that upon dissolution thereof the antimicrobial agent is eluted and pores or voids are created in the foam matrix.
