Abstract
Disclosed is an encrustation and bacterial-resistant coating for use on medical devices and in other medical-related applications. The coating includes a reaction product formed by the covalent linkage of a hydrophilic polyurethane prepolymer and aminopolycarboxylic acid. A urease inhibitor and/or an antibacterial agent may also be added to the coating.
Claims28
A coating for polymeric products used in medical applications, said coating comprising:
- a reaction product formed by a covalent linkage of a hydrophilic polyurethane pre-polymer and aminopolycarboxylic acid.
A coating for polymeric products used in medical application, said coating comprising:
- aminopolycarboxylic acid;
- a coupling agent for directly linking said aminopolycarboxylic acid to at least one surface of the said polymeric product.
A medical device which is resistant to the formation of encrustation or bacteria for use in medical applications, said device comprising:
- a base material formed in a desired shape;
- a coating covering at least one surface of said base material, said coating including
- a reaction product resulting from a covalent linkage of said hydrophilic polyurethane pre-polymer with a aminopolycarboxylic acid.
A polymeric device for use in medical applications, said device comprising:
- a base material formed out of a polymeric material into desired shape;
- a coating covering at least one surface of said base material, said coating including:
- an aminopolycarboxylic acid;
- a coupling agent for directly linking said aminopolycarboxylic acid to at least one surface of said base material.
