Abstract
The present invention is a device and method for making electro-surgical devices, such as electro-surgical blades, that have a thin coating of non-stick material with a narrow continuous gap, or stretch of opening, in the coating, exposing the metal surface along an edge. This opening has a shape that tends to prevent it being clogged by charred tissue in use. The present invention includes a method of manufacturing the devices that has fewer steps than the prior art, and a better way of forming an opening in the electrically insulating non-stick coating to electrically expose the metal beneath.
