1-20. (canceled)
A method of manufacturing a medical device, comprising:
- obtaining an elongate substrate comprising a metal or a metal alloy;
- applying a first composition to an exterior of the elongate substrate to form a first coating layer, wherein the first composition comprises a polyethersulfone;
- applying a second composition to form a second coating layer, wherein the second composition comprises a fluoropolymer and a polyimide.
A method of manufacturing a medical device, comprising:
- obtaining an elongate substrate;
- applying a first composition to form a first coating layer, wherein the first composition comprises a fluoropolymer and a polyimide, and wherein the first coating layer forms an outer surface.
A method of manufacturing a medical device, comprising:
- obtaining an elongate substrate comprising a metal or a metal alloy;
- applying a first composition to an exterior of the elongate substrate to form a first coating layer, wherein the first composition comprises a polyethersulfone;
- applying a second composition to form a second coating layer, wherein the second composition comprises a polyethersulfone;
