Title:
MEDICAL COATING AGENT AND MEDICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/162926
Kind Code:
A1
Abstract:
This medical coating agent comprises a polymer including a structural unit (A) derived from an ethylenic unsaturated monomer having a urea bond. The polymer contained in the medical coating agent satisfies Condition (i) in a case where a 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 letting the polymer absorb water and then heating the polymer at a rate of 5°C/min using a differential scanning calorimeter. Condition (i): The intermediate water amount in the water saturation state is not less than 3.0 mass% with respect to the entire amount of the polymer in the water saturation state.
