Surgical needle coatings and methods |
摘要 |
The present invention provides improved medical devices for use in surgical procedures and methods for manufacturing improved medical devices. In some embodiments, the improved medical devices can include improved surgical needles that are capable of being repeatedly passed through tissue using minimal force. More particularly, the improved surgical needles can be manufactured with two or more different coatings that provide the surgical needles with both durability and lubricity for ease of repeated and successive passes through tissue. Improved methods for manufacturing the surgical needles and for providing and applying coatings to the surgical needles are also provided. |

1. A method for coating a surgical needle, comprising:
positioning a surgical needle having a tissue-penetrating end and a suture attachment end between first and second nozzles, the first and second nozzles being opposed to and facing one another; positioning a tip of each of the first and second nozzles at a non-zero angle relative to a horizontal plane; activating the first and second nozzles, with the tips positioned at the non-zero angle relative to the horizontal plane, to apply, as a liquid, a base coating onto a surface of the surgical needle positioned between the first and second nozzles such that at least a portion of the surgical needle proximate to a carrier having the surgical needle mounted thereon is substantially perpendicular to the horizontal plane, wherein the first and second nozzles are disposed on opposite sides of the surgical needle with respect to a longitudinal axis of the surgical needle; wherein each of the first and second nozzles dispenses a rotating spray of coating particles that swirl around the surgical needle to coat the surgical needle. |
