Abstract:
A method for applying a polymer coating to an elongate intracorporeal device comprising:a) providing an apparatus for applying a polymer coating to an elongate intracorporeal device comprising: a guide chamber having an input end with an input port and an output end, an extrusion orifice disposed at the output end of the guide chamber in fluid communication with the guide chamber, a heater member in thermal communication with the guide chamber, and a cartridge advancement mechanism disposed adjacent the guide chamber; b) placing an extrudable polymer cartridge into the guide chamber; c) placing the elongate intracorporeal device through the extrusion orifice and at least a portion of the extrudable polymer cartridge; and d) activating the heater member to heat the extrudable polymer cartridge and soften it adjacent the extrusion orifice and translating the elongate intracorporeal device in a direction of extrusion while applying a force in the direction of extrusion on the extrudable polymer cartridge with the cartridge advancement mechanism.
