Abstract
The present invention provides metal medical devices which are provided with sliding properties (lubricity), low protein adsorption properties and low cell adsorption properties and further in which these properties are prevented from deteriorating. The present invention relates to a metal medical device having a surface at least partially treated with a copolymer C of a polymerizable silane compound A and a polymerizable compound B that contains a functional group.
Claims6
A metal medical device, having a surface at least partially chemically bound to a copolymer C of a polymerizable silane compound A and a polymerizable compound B that contains a functional group, wherein the polymerizable compound B is at least one selected from the group consisting of a compound of Formula (2) and a compound of Formula (5-1):
- wherein R21 represents a hydrogen atom or a linear or branched C1-C3 alkyl group;
- R22 represents a linear or branched C1-C5 alkylene group;
- and X represents a metal salt-containing hydrophilic group wherein the metal is an alkali metal or an alkaline earth metal,
- wherein R41 represents a hydrogen atom or a methyl group, and p1 and q1 each represent an integer of 1 to 10.
A metal medical device, having a surface at least partially chemically bound to a polymer (e), the polymer (e) being obtained by reacting a copolymer (c) with a silane compound (d), the copolymer (c) being formed from a polymerizable compound (a) that is reactive with the silane compound (d), and a polymerizable compound (b) that contains a functional group,
- wherein the polymerizable compound (b) is at least one selected from the group consisting of a compound of Formula (2) and a compound of Formula (5-1):
- wherein R21 represents a hydrogen atom or a linear or branched C1-C3 alkyl group;
- R22 represents a linear or branched C1-C5 alkylene group;
- and X represents a metal salt-containing hydrophilic group wherein the metal is an alkali metal or an alkaline earth metal,
- wherein R41 represents a hydrogen atom or a methyl group, and p1 and q1 each represent an integer of 1 to 10.
