Stent Coating Device
First Claim
1. A system for applying a coating to a prosthesis, the system comprising:
- an applicator, the applicator being configured to apply the coating to the prosthesis; and
an applicator controller, the applicator controller being configured to communicate with the applicator, the applicator controller being adapted for on-the-fly coating wherein a translation of the applicator and a drop-on-demand delivery by the applicator are substantially synchronous.

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.

11. A computer program comprising:
-
a program code for providing a prosthesis having identifiable features; a program code for pre-scanning the prosthesis prior to coating to identify the features and to obtain coating coordinates for the features; and a program code for depositing a coating material at desired regions of the prosthesis as a function of the coordinates. - View Dependent Claims (12, 13, 14, 15)

16. A system for applying a coating to a prosthesis, the system comprising:
-
an applicator; a detector; and a processing unit; the processing unit being programmed with a length of the prosthesis; a desired incremental linear movement; a desired incremental angular movement; and a reference point; the detector being configured to look for a target on the prosthesis, the detector being configured to send a signal to the applicator to drop-on demand when a target is found; the detector and the applicator being configured to complete a plurality of linear paths and a plurality of angular moves, each linear path being separated by an angular move, a first linear path beginning at the reference point; each linear path comprising a plurality of incremental linear movements, the sum of the plurality of incremental linear movements being at least equal to the length of the prosthesis; and each angular move being equal to the desired incremental angular movement, the sum of the plurality of incremental angular movements being at least equal to 360 degrees.
