CRESCENT DESIGN was incorporated in April of 1987 as a design-engineering firm creating custom electronic, software, and mechanical equipment. Early in 1989 a major medical company (Medtronic) contracted us to design and build them a “burst tester” and in 1991 a second major medical company (Advanced Cardiovascular Systems) contracted us to improve the design and performance of their “rupture tester”. After receiving requests for burst testers from other medical companies we committed to designing our own proprietary instrument and began shipping the HBLT in 1994. They have remained in continuous production and are now used by over 300 different customers in 35 different countries. All but a handful remain in daily service and have become the world wide quality standard for hydraulically testing a wide range of medical devices.

Crescent Design remains a customer-centered company that strives to provide extraordinary service. We continue to improve the performance and reliability of our Hydraulic Burst Leak Testers. We respond to customer needs by adding features and accessories that improve product-testing throughput and operator usability.
