In the world of medical devices, smaller is better. Devices that can be implanted in the human body with minimally invasive procedures improve patient health, speed recovery, limit expensive hospital time, and make new treatment options possible.
Coronary stents, for example, open blocked arteries from within the blood vessels. Inserted with a guide wire and expanded when in place, these intricately laced metal tubes are studies in precision. Metal must be cut to such fine specifications, maintaining the strength and integrity to do its healing work, that manufacturing them has become an arduous process. Traditional micro machining tools generate heat that damages the part, causing melting, burring and recast. Several steps are required to clean, hone, debur, etch and polish the stents so that they can be used, and at each step part consistency and quality is at risk.
Trade journal Today’s Medical Developments highlighted the capabilities of the Raydiance medical precision manufacturing solution, noting its “dramatic return on investment…particularly considering the elimination of multiple post-processing steps with the athermal processing.”
Raydiance machining has indeed proven to upend the economics of manufacturing implantable medical devices. By cutting to ultrafine specifications in a single process, product quality and cost per part are both significantly improved. In addition to cutting metal stents, Raydiance solutions are also able to cut bioabsorbable polymer stents—stents that dissolve once their life-saving work is done. No other technology is able to machine these very soft materials.
Raydiance medical precision manufacturing solutions are at work around the world, displacing traditional processes that are just too slow and too expensive. One manufacturer has cited an 80 percent reduction in price per part—giving them a more competitive product with eye-popping price leverage.
Additional medical device applications for Raydiance solutions include the guide wires used to deliver implantable devices, scaffolding for implantable heart valves, and suture holes in that scaffolding that allows the valve to be sewn more precisely to heart tissue.
