Abstract
The present invention relates to methods for coating at least one surface of a medical device for improving the hemocompatibility of said surface. Further, the invention relates to medical devices comprising surfaces, coated with a coating composition containing a nonionic ester formed from an acyclic C3-C6(OH)3-6 polyol and from at least three C12-C26 fatty acids, and further includes at least one hydrophilic group.
Claims17
Method for coating at least one surface of a medical device, said surface coming into contact with blood, wherein the method comprises
- providing a medical device having at least one surface intended to come into contact with blood,
- coating at least a portion of said surface with a coating composition containing a nonionic ester, the ester being formed from an acyclic C3-C6(OH)3-6 polyol and from at least three C12-C26 fatty acids, where the ester further includes at least one hydrophilic group, to provide a medical device with an improved hemocompatibility.
A medical device having at least one surface intended to come into contact with blood, said surface having a coating comprising a nonionic ester formed from an acyclic C3-C6(OH)3-6 polyol and from at least three C12-C26 fatty acids, where the ester further includes at least one hydrophilic group.
Coating composition comprising a nonionic ester formed from an acyclic C3-C6(OH)3-6 polyol and from at least three C12-C26 fatty acids, where the ester further includes at least one hydrophilic group for improving the hemocompatibilty of at least one surface of a medical device, said surface coming into contact with blood.
Method for improving the hemocompatibility of at least one surface of a medical device, said surface being intended to come into contact with blood, wherein the method comprises
- providing a medical device having at least one surface intended to come into contact with blood,
- coating at least a portion of said surface with a coating composition containing a nonionic ester, the ester being formed from an acyclic C3-C6(OH)3-6 polyol and from at least three C12-C26 fatty acids, where the ester further includes at least one hydrophilic group, to provide a medical device having at least one surface with an improved hemocompatibility.
