    摘要: 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.

    摘要: Process for the production of elastic tapes from thermoplastic polyurethane elastomers, wherein the thermoplastic is extruded to form a flat or tubular film and is slit in the usual manner, the extruded film being oriented lengthwise at least in the ratio of 1:1.5, cooled and stored until the modulus of elasticity has increased by at least 25%, measured according to DIN 53,455, before the film is slit, and the use of these tapes for the production of elastic seals.
