THIN-FILM COATED FLUOROPOLYMER CATHETER

摘要

A fluoropolymer medical device (e.g., a sphincterotome) has a thin-film coating deposited using a technique such as Atomic Layer Deposition. The thin-film coating may be a ceramic coating or a metal coating and a ceramic coating may further have an overlying ink coating such as a conducting ink or a radiopaque marker. The ceramic coating improves the application and adherence of the ink coating to the fluoropolymer device.

主权项

1. A fluoropolymer medical device comprising:
an elongated tubular fluoropolymer body having an outer surface, a proximal end portion, a distal end portion, and a lumen extending at least partially through the distal end portion; one or more ceramic coatings, the one or more ceramic coatings being deposited on the outer surface of the elongated tubular fluoropolymer body by a technique selected from atomic layer deposition, pulsed laser deposition, molecular beam epitaxy, sputter deposition, laser induced forward transfer, matrix assisted pulsed laser evaporation, and matrix assisted pulsed laser evaporation direct write; and one or more outer coatings, the one or more outer coatings independently comprising an ink coating or an adhesive coating, the one or more outer coatings being adhered to the one or more ceramic coatings.
