The Challenge
A global manufacturer of medical devices was developing a new implantable drug-delivery system. Extreme demands for reliability, precision, and absolute seal were matched by the already strict regulatory requirements for biocompatibility and compatibility with the drugs the new system was dispensing within the body.
As an implanted device, achieving zero-leakage tolerances (5 x 10-9 scc/sec helium) and extended cycle life were essential to the long-term success of the new device. Further, a light spring rate was required in order to work in concert with the entire component.
