Consider the medical guidewire. How could anything be simpler? Actually, few things are more important to the medical professional and the patient. In procedures of cardiology, neurology and thoracic surgery, the medical guidewire travels to the target organ by way of the venous system.
Accordingly, the medical guidewire must embody the ideal of its design. It must be perfection in physical, technological form. It should have a flawless surface, but a lot could happen in production without sufficient care. So, the medical guidewire is stripped of its rigid polymeric insulating layer by excimer laser machining or femtosecond laser machining, based on the type of insulation. Does that sound simple? Again, consider that the guidewire can be as thin as a human hair.
