Method and apparatus for polymer application to intracorporeal device

摘要: A method and apparatus for applying a polymer coating on an elongated substrate, preferably elongate intracorporeal device in the form of guidewire. An extrudable cartridge is moved by advancement mechanism into guide chamber which heated at end with die or orifice through desired portion guidewire may pass be coated. Parameters such as temperature, pull speed force exerted controlled computer program order to achieve repeatable results. The chamber, cartridge, die, push tube all made from components can reused disposed after single use. have variety configurations including multiple layers different materials, eccentric shapes, lumens elements drawn coated asymmetric disposition materials respect longitudinal axis viewed transverse cross section give bending properties having preferred direction device.
