At Gateway Laser we produce highly precise components with our laser micromachining capabilities for new applications including:
Medical Devices: Laser Drilled Catheters
Catheter hole drilling using lasers is widely used when the hole size required is less than .010” or when patterning holes arrays in multi-lumen catheters. Laser machining provides a fast and highly repeatable hole drilling process with tolerances well below +/-.001”. In each case, the combination of catheter material, wall thickness, hole size or geometry of hole arrays have to be carefully evaluated to determine the type of laser system and machining parameters that meet both manufacturing requirements.
The following photos depict the edge quality of holes drilled in typical catheter materials:

Selective Scribing Using Excimer Laser System.
View shows laser scribing of 50um wide lines through multilayer metal coating (total metal thickness 5um) without damaging glass substrate. This method can be used to form electrodes, create metal particles or repair defects in metal on ceramics circuitry.
