Abstract: The embodiments herein discloses a linear seal system for interconnecting flow controller modules in a fluid flow controller. The system comprises a flow sensing module is coupled to an inlet connection module to measure a fluid flow rate to generate a sensor output signal. A flow control valve module is coupled to the flow sensing module to provide a user desired flow rate through an outlet connection module. An electronic control system is configured to regulate an operation of the flow sensing module and the flow control valve module based on the command signal to achieve a desired flow rate. A linear track system provided to support all the modules in a linear arrangement, includes a dovetail locking configuration. The linear track has two rod/screws to compress the seals between the modules.

Abstract: A prosthetic heart valve testing apparatus is disclosed. The apparatus comprises a test chamber, a slide plate slidingly and sealingly coupled to the test chamber, the slide plate having an opening formed therein that is adapted to receive a prosthetic heart valve to be tested in the test chamber, a storage member containing a plurality of prosthetic heart valves to be tested in the test chamber, and a load/unload means for transferring at least one of the heart valves in the storage member between the storage member and the slide plate. A method disclosed herein comprises positioning the storage member in a first position, moving a first heart valve from the storage member in the first position to the test chamber, performing at least one test on the first heart valve in the test chamber, and returning the first heart valve from the test chamber to the storage member.
