The s-Pulse HP ultrafast laser from Amplitude Systemes is designed to process medical devices such as stents, percutaneous valves, catheters or even electrodes. It can cut cobalt-chrome and nitinol stents as well as polymer stents with no heat effects and thus without changing material properties. As a result the shape-memory capacity of the alloy will remain unchanged.
The s-Pulse HP generates ultra-short pulses under 500 femtoseconds enabling the processing of stents and brain micro stents without any burrs, recasting or micro-cracking. The stent keeps all its original properties such as radial strength and the ability to twist itself inside the coronary arteries.
The s-Pulse HP is a versatile equipment offering, with the same laser, high energy capabilities (up to 2mJ) for thick stents, but also high repetition rate (up to 300kHz) for high cutting speed.
This technology strongly improves the throughput in stent manufacturing by reducing post processing. The s-Pulse HP is available with infra-red, green and UV output.
