Testing and Inspection Providers Attempt to Stay Fluid
in Changing Times


As medical products evolve, the methods and equipment used for testing them often must follow suit. In today's climate especially, the sheer number of new and innovative medical devices is testing the problem-solving abilities of testing providers.

"These devices are highly specialized and we are having to tweak our processes on a case-by-case basis in order to accommodate them." Another trend necessitating new testing methodologies is the increasing number of patient-specific devices, Nelson says. In these cases, each unit has unique dimensions and contours. Such customization requires special care in devising procedures for sterilization and microbial testing. Read More
