​Medical Device Quality, Patient Safety Enhanced With Eastman Tritan™ Copolyester

Collaborations with Dymax, Natus Medical to be showcased at MD&M West Show


Kingsport, Tenn., USA Feb. 10, 2015 — Eastman Chemical Company is finding new ways to help medical device companies boost product quality and patient safety with Eastman Tritan™ copolyester. Medical adhesives developed by Dymax Corporation, a hearing screener developed by Natus Medical Incorporated and small bore connectors developed by A. Hopf GmbH are relying on the new-generation copolyester to meet customer needs and regulatory requirements while ensuring confidence in the end device.

Dymax’s medical device adhesives, Natus Medical’s Echo-Screen® III hearing screener and Eastman’s work on small-bore connectors will be featured at the Medical Design & Manufacturing (MD&M) West trade show in Anaheim, California, Feb. 10 to 12. These innovations demonstrate the adaptability of Eastman Tritan™ copolyester, which is tough, free of bisphenol A (BPA) and resistant to aggressive cleansers and disinfectants.

“Eastman Tritan™ copolyester can help improve medical device reliability and patient safety in a variety of ways — from a toughness that can translate into reduced device failure to collaborations that can ensure quality materials work well together,” said Ellen Turner, market development manager, specialty plastics, medical devices, Eastman. “Ultimately, the material provides greater peace of mind for health care professionals and patients.”

Collaboration produces a comprehensive solution
Dymax — a leading manufacturer of advanced light-curable adhesives, coatings, oligomers, light-curing equipment and fluid dispense systems — teamed with Eastman for an efficient and dependable process to create value-added solutions.

Through their joint testing, the companies found that pairing Eastman Tritan™ copolyester with select Dymax medical device adhesives provided the tough, reliable, BPA-free combination that customers need. Now, the companies have a full list of products that have been tested for biocompatibility, are supported by test data and can be recommended early in the development of new devices. The collaboration will reduce time to market for lifesaving innovations.

“Our customers value efficiency and reliability throughout the design and validation process. The sooner they can deliver safe medical devices to market, the sooner patient outcomes can be improved,” said Mark Pizzuto, global market segment manager, medical, for Dymax. “Building a bridge along the supply chain requires companies with shared values, extensive experience, and a willingness to work together. We found that Eastman valued a complete customer solution and worked with the customer needs top of mind similarly to Dymax.”

Delivering functionality in infant care
Natus Medical’s Echo-Screen® III hearing screener, made with Eastman Tritan™ copolyester MXF121, is used primarily for newborn hearing screening. This compact, all-in-one device incorporates transiently evoked otoacoustic emissions (TEOAE), distortion product otoacoustic emissions (DPOAE) and auditory brainstem response (ABR) capabilities. To answer customer needs, the global leader in newborn hearing screening solutions established new material requirements for its infant care products. The Echo-Screen III hearing screener — originally designed and tooled using polycarbonate (PC)/acrylonitrile butadiene styrene (ABS) alloy — now features Eastman Tritan™ copolyester MXF121, which is manufactured without BPA and has superior chemical resistance, along with excellent mechanical properties, impact resistance and moldability. Tritan MXF121 also is made without halogens and ortho-phthalate plasticizers.

Launched at MD&M West 2014, Eastman Tritan™ copolyester MXF121 has helped Natus Medical proactively address patient safety concerns. “The Natus development team was able to meet user requirements for a DEHP-free and BPA-free product by partnering with Eastman on material selection,” said Jim Hawkins, president and CEO of Natus Medical.

Addressing the need for consistency, improved patient safety
Injection molder and mold maker A. Hopf GmbH selected Eastman Tritan™ copolyester as a raw material suitable for a newly designed small-bore connector. The connector addresses growing concerns for medical-device misconnections, which prompted a search for consistent, easier-to-use and safer small-bore connectors. The Global Enteral Device Supplier Association (GEDSA) already has seen regulatory changes to this effect with the International Organization for Standardization (ISO) standard for connectors for enteral applications, ISO/DIS 2 80369-3. A. Hopf GmbH proactively addressed this with a consistent design for enteral connectors according to the new requirements.

“While working on the new design of a standard connector, we also had to consider the material that would be used in its development,” said Michael Hopf, sales manager, A. Hopf GmbH. “At A. Hopf GmbH, we saw Eastman Tritan™ copolyester as the future raw material for medical-device connectors such as stopcocks and y-connectors because it’s a BPA-free, new-generation copolyester that
provides toughness, chemical resistance and stability post-sterilization.”

Eastman Tritan™ copolyester maintains clarity and color after sterilization, providing excellent aesthetic appeal and helping boost patient and health care provider confidence. In addition, devices retain clarity and functional integrity following ethylene oxide and gamma sterilization.

Eastman will showcase these relationships and innovations at the MD&M West trade show, Feb. 10 to 12, in Booth 2515. Visitors also can speak with the Dymax team at Booth 2239 during the show.
