ABSTRACT:
This invention relates to a new technique for preparing metal devices such as guidewires for the subsequent attachment of hydrophilic coatings. The invention also relates to guidewires and other devices made according to that method.
In one embodiment of the method of this invention, a hydrocarbon residue undercoat is applied to a metal guidewire core by plasma deposition. A photoactive hydrophilic polymer is then deposited on the hydrocarbon residue coating and activated by ultraviolet light. The hydrocarbon residue coating acts as a tie layer between the hydrophilic polymer and the metal guidewire core apparently by providing C--C bonds for the covalent linking of the coating material to the tie layer. The resulting article of this invention is a guidewire having the maneuverability of a metal guidewire and the biocompatibility of a lubricious, hydrophilic polymer.
