Beschreibung
Zusammenfassung:	A surgical device includes a substrate and a first coating that covers at least a portion of the substrate. The first coating includes a first polymer. The first coating having antibiotics dispersed in the first polymer such that the first polymer releases the antibiotics as the first polymer degrades. A second coating covers at least a portion of the first coating. The second coating includes a second polymer. The second coating has ellagic acid dispersed in the second polymer such that the second polymer releases the ellagic acid as the second polymer degrades. In some embodiments, systems and methods are disclosed. Un dispositif chirurgical comprend un substrat et un premier revêtement qui recouvre au moins une partie du substrat. Le premier revêtement comprend un premier polymère. Le premier revêtement a des antibiotiques dispersés dans le premier polymère de telle sorte que le premier polymère libère les antibiotiques lorsque le premier polymère se dégrade. Un second revêtement recouvre au moins une partie du premier revêtement. Le second revêtement comprend un second polymère. Le second revêtement a de l'acide ellagique dispersé dans le second polymère de telle sorte que le second polymère libère l'acide ellagique lorsque le second polymère se dégrade. Dans certains modes de réalisation, l'invention concerne des systèmes et des méthodes.
