Amplitude Systemes (Bordeaux, France) offers the s-Pulse HP ultrafast laser, designed to process medical devices such as stents, percutaneous valves, catheters, and electrodes. It can cut cobalt-chrome and Nitinol stents as well as polymer stents with no heat effects, without changing material properties. The shape-memory capacity of the alloy remains unchanged. The laser generates ultra-short pulses under 500 femtoseconds, enabling the processing of stents and brain micro stents without any burrs, recasting, or micro-cracking. It offers high energy capabilities (up to 2mJ) for thick stents and high repetition rate (up to 300 kHz), and is available with infrared, green, and UV output.
