Developing bio-compatible, durable and cost-effective nano-structured alloys that are ideal for use in cutting-edge medical devices.
Nano-structured metals offer a variety of advantages over conventionally produced alloys, including higher strength, improved processing capabilities, and novel biological properties.
However, there are no nano-structured metal alloys used in the manufacture of medical devices. That’s because existing techniques either produce hard-metal alloys for mass production that aren’t suitable for medical devices, or are used with softer metals than surgical-grade stainless steel or other medical alloys.
Rosies Base LLC, a Boston-based startup, is the only supplier in the world of nanoSUS, a stainless-steel alloy that bridges that gap. Building on seven decades of precision manufacturing expertise, a proprietary metallurgical rolling process allows Rosies Base to mass-produce ultra-fine-grained metal alloys that are thinner and stronger than standard alloys.
The first alloy developed by Rosies Base, nanoSUS, uses surgical-grade stainless steel for its “mother material,” but is twice as strong and easier to process than its parent – reducing finishing times by as much as 50 percent.
Those advances in strength and processing make nanoSUS the ideal material for a variety of medical device applications, including minimally-invasive surgery, orthopedic implants, robotic surgery instrumentation, catheter guidewires, needles, cannulae, and other micro-processed medical device components.
