Stent coating device
First Claim
1. A method for coating comprising:
- (a) providing a prosthesis having identifiable features;
(b) pre-scanning said prosthesis prior to coating to identify said features and to obtain coating coordinates for said features; and
(c) applying a coating material at desired regions of the prosthesis as a function of said coordinates.

Abstract
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 inkjet 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 or simply disposed of.
