Abstract:
A coating apparatus for coating the balloon portion of a balloon catheter is described. The coating apparatus includes a rotatable member in which the catheter portion of the balloon catheter is mounted and fixed, and which causes rotation of the balloon catheter. The apparatus also includes a support member in which the distal tip of the catheter is inserted and free to rotate; and a spray nozzle directing sprayed material on the balloon surface. The inventive configuration of the coating apparatus allows the balloon catheter to be rotated along its axis with insubstantial or no wobble, which significantly improves the quality of the coating applied to the surface of the balloon.
