The present invention is a method and device, which is suitable for use in an operating theater just prior to implantation, for selectively applying a medical coating to an implantable medical device, for example a stent. Disclosed is a device for use with a stent deployed on a catheter balloon. The device is configured to apply a medical coating of a desired thickness to the surface of a stent only. This is done by use of a drop-on-demand ink-jet printing system in association with an optical scanning device. The device is further configured so as to, if necessary, apply a plurality of layered coats, each layered coat being of a different coating material, and if appropriate, different thickness. The section of the housing in which the stent is held during the coating procedure is detachable from the housing base. The detachable housing section may be easily cleaned and re-sterilized or simply disposed of.
A coating method for selectively applying a coating to surfaces of a stent, the method applying the coating based upon optical properties of the surfaces such that the coating is applied to surfaces of the stent and is not applied to surfaces of a balloon portion of a catheter on which the stent is mounted, the surfaces of the stent being optically distinguishable from the surfaces of the balloon portion of the catheter, the coating method comprising:
