Abstract
A method of forming a coated medical device is described. A coating may be applied inline to a continuous tubing formed by extrusion, prior to cutting and secondary operations. Thus, inefficient and labor-intensive steps associated with preparing individual tubes for coating may be avoided. The method may include forcing a flowable material through an exit port of an extruder, depositing a coating onto at least a portion of the continuous length of extruded tubing after the tubing is forced through the exit port, cutting the coated tubing to a desired length after depositing the coating, and performing one or more secondary operations on the coated tube at a temperature in the range of from about 15° C. to about 375° C.
