Laser Welding Technology To the Rescue of Heart Failure
There is now hopes for late stage heart failure patients.
Terumo Heart Inc., a medical device subsidiary of Terumo Corp., has achieved a breakthrough with its production of a left ventricular assist system (LVAS).
DuraHeart LVAS is designed to provide auxiliary pumping power in patients with late-stage heart failure and has earned marketing approval in Europe. There are also clinical trials in Japan and United States.
The anticipated increase in product demand forced the company to reevaluate its manufacturing capabilities to ramp up production. Upgrading the laser welding technology emerged as pivotal in meeting this goal.
This article traces the steps Terumo Heart took to identify and customize a laser welding process that would facilitate a fourfold increase in throughput without sacrificing quality or precision of design and function.
