Abstract
An object of the present invention is to provide a simple method for manufacturing a coated medical device allowed to have not only properties such as sufficient hydrophilicity but also a bacteria adhesion inhibiting capability. The present invention provides a method for manufacturing a coated medical device, including: (A) a contacting step of housing a medical device in a container, and bringing the medical device into contact with a solution a containing a hydrophilic polymer A; and (C) a heating step of heating the container; wherein the hydrophilic polymer A is a polymer containing, as a monomer unit, a compound having a quaternary ammonium cation group; and wherein the pH of the solution a after the heating step is 6.1 to 8.0.
Claims11
A method for manufacturing a coated medical device, comprising:
- (A) a contacting step of housing a medical device in a container, and bringing said medical device into contact with a solution a containing a hydrophilic polymer A;
- and
- (C) a heating step of heating said container;
- wherein said hydrophilic polymer A is a polymer containing, as a monomer unit, a compound having a quaternary ammonium cation group represented by the following general formula (I):
- wherein, in the general formula (I), R1 represents an optionally substituted C1-20 divalent organic group;
- and R2 to R4 each independently represent an optionally substituted C1-20 alkyl group or an optionally substituted C6-20 aryl group;
- and
- wherein the pH of the solution a after said heating step is 6.1 to 8.0.
