Method and apparatus for coating a medical device
First Claim
1. A method, comprising:
- optically scanning an object to produce a digitized representation of the object;
processing the digitized representation to distinguish a first portion of the object from a second portion of the object;
determining a first set of locations in a first coordinate system for a plurality of locations on the first portion of the object; and
converting the first set of locations in the first coordinate system to a corresponding second set of locations in a second coordinate system.

Abstract
A method and device, for use in an operating theater just prior to implantation, for selectively applying a medical coating to an implantable medical device. Disclosed is a device for use with a stent deployed on a catheter balloon configured to apply a medical coating of a desired thickness to the surface of the stent only. A drop-on-demand inkjet printing system in association with an optical scanning device is described. The device is further configured to apply a plurality of layered coats, each layered coat being of a different coating material, and if appropriate, different thickness and to coat a portion of the medical device as a function of its geometric configuration. The coating is applied by moving an applicator over the device in a path that is independent of the deposited coating pattern.

10. A method of coating a medical device, the method comprising:
-
generating a representation of the medical device;
processing the generated representation to generate a topology of the medical device;
determining a first plurality of locations on the generated topology wherein each location of the first plurality of locations corresponds to a location on the medical device at which at least one drop of a coating material is to be placed;
generating a second plurality of locations as a function of the first plurality of locations, wherein each location of the second plurality of locations defines a physical point on the medical device; and
depositing at least one drop of coating material on at least one location in the second plurality of locations. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 24, 25, 26, 27)

20. A method, comprising:
-
optically scanning an object to produce a digitized representation of the object;
processing the digitized representation to distinguish a first portion of the object from a second portion of the object;
identifying at least one feature area of the first portion of the object and determining a type of the identified at least one feature area; and
determining at least one characteristic of a coating material to be placed at the identified at least one feature area of the first portion of the object as a function of the determined type. - View Dependent Claims (21, 22, 23)
