A manufacturer of ceramic-to-metal assemblies has expanded its production cleanroom for feed-throughs for such medical implant applications as cardiac rhythm management, neuromodulation, and cochlear and middle ear hearing devices. The cleanroom environment provides reliability and ensures that the implantable feed-throughs will not be exposed to contamination. The manufacturer specializes in addressing application problems that commonly involve extremes of temperature or pressure, a challenging operating environment, or complicated product geometry.
