ABSTRACT:
Surgical needles are fabricated by masking and etching a plurality of the needle blanks from both sides of a sheet of base material such as metal, applying an adhesive backing to one etched side and then etching the other side of the sheet as a chemical milling process. The resultant needles may be unattached to each other and individually removable from the backing. This increases the speed of manufacturing while maintaining the ease of use.
