MEDICAL COATING AGENT AND MEDICAL DEVICE

WIPO Patent Application WO/2023/054500

A1

This medical coating agent contains a polymer having a structural unit (A) derived from an ethylenic unsaturated monomer having an urethane bond. The polymer contained in the medical coating agent satisfies condition (i) in a case where the polymer water-holding state, when the peak top of heat absorption due to the melting of ice appears at 0°C, is defined as a water saturation state, in a DSC curve obtained by causing the polymer to absorb water and heating the polymer at a rate of 5°C/min using differential scanning calorimeter. Condition (i): The intermediate water amount in the water saturation state is at least 2.0 mass% with respect to the entire amount of the polymer in the water saturation state.
