Abstract

The present invention is directed to a method for manufacturing a medical device having a coated portion which comprises obtaining a structure having an inner surface and an outer surface; coating at least a portion of the inner or outer surface with a first coating material; and ablating the coated tubular structure with a laser to form at least one opening therein to form the coated portion. A plate can be used instead of the structure, and the plate is folded to form the structure after the ablation. A plurality of medical devices, made of any materials and having uniform coating(s), can be easily manufactured by the method of the present invention.

Claims

7. The method of claim 7, wherein the first coating material and the second coating material are the same.

13-1. The method of claim 1, which further comprises cutting the coated structure into sections to form more than one coated portion.

15. A method for manufacturing a coated medical device having a coated portion which comprises the steps of:

(a) obtaining a plate having a first surface and a second surface;

(b) coating at least a portion of the first surface or second surface which a first coating material;

(c) ablating the coated plate with an ulrashort-pulse laser to form at least one opening therein; and

(d) forming the coated portion with the ablated plate.
