Abstract
An angiographic catheter has a relatively stiff though flexible shaft and a soft tip. The soft tip consists primarily of a tungsten loaded polyether block amide (PEBA) copolymer surrounded by two thin PEBA layers. This three ply radiopaque tip is bonded to a PEBA shaft. The shaft is reinforced either by a inner nylon ply or by metal braiding.
