Abstract:
An insertable medical device comprising an abrasion resistant biocompatible surface coating applied to an inert surface of the device, the inert surface having no reactive functional groups, the surface coating comprising:(a) a coherent bond coat layer applied to the inert surface comprising at least one bonding polymer bonded with non-covalent bonds with the inert surface of the device without the need for penetration into the inert surface, and further comprising(b) at least one outer layer applied to the bond coat layer that adheres to the bond coat layer, the coating remaining adherent to the surface and resistant to abrasion and to removal from the device after soaking in water relative to a coating without the bond coat layer, and the coating remaining adherent when subjected to bending through a small radius.
