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.
Claims31
A method for manufacturing a coated medical device having a coated portion having at least one opening therein, wherein the method comprises the steps of:
- (a) obtaining a metal structure having an inner surface and an outer surface;
- (b) coating at least a portion of the inner or outer surface of the structure with a first non-metallic coating material to form a coated structure;
- and
- (c) simultaneously ablating through the coating material and structure of the coated structure with an ultrashort-pulse laser to form at least one opening therein.
A method for manufacturing a coated medical device having a coated portion having at least one opening therein, wherein the method comprises the steps of:
- (a) obtaining a metal plate having a first surface and a second surface;
- (b) coating at least a portion of the first surface or second surface with a first non-metallic coating material to form a coated plate;
- (c) simultaneously ablating through the coating material and plate of the coated plate with an ultrashort-pulse laser to form at least one opening therein;
- and
- (d) forming the coated plate into a tubular medical device.
A method for manufacturing a coated medical device having a coated portion having at least one opening therein, wherein the method comprises the steps of:
- (a) obtaining a metal structure having an inner surface and an outer surface;
- (b) coating at least a portion of the inner or outer surface of the structure with a first non-metallic coating material to form a coated structure;
- and
- (c) simultaneously ablating through the coating material and structure of the coated structure with a laser to form at least one opening therein.
