Hearing implant reliability starts with the design process. Dominik Hammerer and Bernhard Jamnig talk to Manfred Pieber about new device development and steps in the manufacturing process that contribute to reliability, including feasibility, hermeticity, impact, environmental, and vibration testing that ensure all requirements are met. Results from thorough investigations of explanted devices are also considered when designing new implants.  Weblinks: Cochlear Implant Safety and Reliability (medel.pro) Bone Conduction Implant Safety and Reliability (medel.pro)
