MEDICAL DEVICE AND METHOD FOR MANUFACTURING MEDICAL DEVICE

摘要

The invention provides a medical device including a lubricating coating film (surface lubricating layer) that exerts excellent lubricity and durability. The medical device of the invention includes, on a base layer, a surface lubricating layer formed from a block copolymer having a hydrophilic portion and a hydrophobic portion that bears a reactive functional group. The existence ratio of the hydrophobic portion of the block copolymer in an outermost surface of the surface lubricating layer is 20 to 45 mol%, and the viscosity of a 1 wt% chloroform solution of the block copolymer in an environment at a temperature of 30°C is 8 to 30 mPa·s.
