ABSTRACT:
A medical implant can include a bioerodible metal portion and a coating overlying the bioerodible metal portion. The coating can include a therapeutic agent and a polysaccharide matrix reversibly cross-linked with polyvalent metal cations. Upon implantation of the implant within a body, the therapeutic agent is released and the bioerodible metal portion erodes to release polyvalent metal cations capable of re-cross-linking the polysaccharide matrix.
