A medical device which can be introduced into the body tissue of a human or animal comprises a matrix of a polyurethane elastomer with organic silicone polymer units built into the main polymer chain and an oligodynamic agent spatially distributed uniformly within the matrix. The oligodynamic agent releases bacteriocidal or microbicidal metal ions when exposed to body tissues. The method for manufacturing the medical device is characterized by the addition of the oligodynamic agent in a solid or dissolved form prior to the reaction of the educts with isocyanate.
