| titleOfInvention | Hollow Microneedle for Subretinal Injection and Extraction and Devices for Subretinal Injection and Extraction |
| abstract | (A) applying a solution of a viscous material to a substrate surface; (b) contacting the frame with a solution of the viscous material; (c) lifting the substrate, the frame or the substrate and the frame such that the contacted frame and the substrate are spaced apart to produce a solid micro needle; (d) applying a curved shape to the solid micro-needle after the step (c) or after the step (c) is completed; (e) depositing a metal on the curved shape-imparted solid micro-needle; (f) metal plating the metal deposited solid micro-needles; (g) beveling the tip of the metal-plated solid micro needle; And (h) removing the solid micro-needles to obtain hollow micro-needles to which a curved shape is imparted. The present invention also provides a method of manufacturing hollow micro-needles for sub-retinal scanning or extraction. The hollow microneedle for sub-retinal scanning or extraction of the present invention is made of metal and has strength or force to pass through the sclera and the retina. The hollow microneedles for subretinal injection or extraction according to the present invention are effective for delivering drugs because the length and curvature angle can reach a suitable position under the retina, for example, the center of the subretinal space where the optic nerve is concentrated, can do. |
