Patent attributes
A medical device and a method of manufacturing the same which excels in lubricity under severe conditions are provided. The medical device according to the present disclosure is inserted into a living body. The medical device includes a resin coating layer that includes a maleic acid polymer substance and is provided on a surface of a base member. The resin coating layer is formed by covalently bonding the maleic acid polymer substance to a reactive functional group which exists on at least the surface of the base member of the medical device. A ratio of a peak height of carboxylate with respect to a total peak height of carboxylic acid ester and a carboxylic acid in the maleic acid polymer substance ranges from 1.2 to 1.7 when being measured through infrared spectroscopy (IR method).
