Abstract
A method for improving the retention between the surfaces of medical devices. The method includes coating a surface of one medical device such as a stent with a coating that includes a functional group and coating a surface of another medical device such as a balloon with a coating that includes an identical or different functional group. The method further includes interacting the coated surfaces to produce a plurality of bonds between the surfaces, thereby improving retention.
Claims9
A method for improving the retention between surfaces of coatings of medical devices, comprising:
- providing a plurality of coated medical devices each having a surface, wherein one said medical device having a coating surface including a first functional group and another medical device having a second functional group;
- wherein the first functional group is a pendant carboxlate group;
- and
- wherein the second functional group is a pendant amine group;
- and
- interacting said surface including the first functional group with said surface including the second functional group to produce a plurality of transient covalent linkages between said surfaces for improving retention between said medical devices.
(canceled)
(canceled)
A combination of medical devices, comprising:
- a plurality of coated medical devices each having a surface, wherein one said medical device having a coating surface including pendant activated carboxlate groups and another medical device having a coating surface including pendant amine groups, wherein said surface including pendant activated carboxlate groups bonds with said surface including pendant amine groups to produce a plurality of transient covalent linkages between said surfaces for improving retention between said medical devices.
