Many physical ailments would go untended if it weren’t for the metals and heat treatments used to repair us. Cobalt chrome alloys, titanium, stainless steel – these and a host of proprietary metals are used in knee and hip joint replacement, fusion cages that relieve pressure on ailing discs, pacemakers and pumps, and the screws and hardware that hold it all together.

Laser Marking for Passivation and Corrosion Resistance

BOTW-50w  Source:  Today’s Medical Developments

The most commonly used medical device materials are stainless steel 304 and 17-4. These materials have a natural passive corrosion-resistant layer, consisting of chromium oxide, which resists repeated sterilization and has an inert surface that will not react inside the body.

During the manufacturing process, multiple machining steps can remove or degrade this passive surface by embedding iron chips and particles into the surface. The material must then be put through passivation to rebuild the passive layer – removing iron from the part’s surface, which also removes potential corrosion sites.

The style of mark required by the medical device industry is called a dark or annealed mark. This mark does not remove any material from the part, avoiding any potential for any contamination to collect. When handling the part, the dark or annealed mark must not be able to be felt on the surface of the material. The heat input needed to build up this oxide layer tends to degrade the passive layer on the marked surface and can cause local migration of alloying elements.

First Accreditation for MedAccred in Europe Awarded to Bodycote

Bodycote, the world’s largest heat treating services provider, is pleased to announce that its Derby, UK location is the first facility in Europe to earn the MedAccred accreditation underlining the high standards of quality achieved. The official approval was awarded on 7th of April 2016.

MedAccred, administered by Performance Review Institute (PRI), is an industry managed approach to ensuring critical manufacturing process quality throughout the medical device supply chain. It establishes stringent consensus audit criteria based on industry and specific OEM requirements that ensure compliance and quality. Adherence to these requirements leads to greater process discipline, operational efficiency and ongoing improvement which results in higher quality and performance.

Strategically located in the East Midlands, Bodycote Derby, which offers heat treatment and hot isostatic pressing (HIP) services, is fast becoming a centre of excellence serving the medical device and implants markets for the UK, Ireland and Europe. Bodycote continues to invest in new capacity and technology to support opportunities within the growing medical industry for classic heat treatment and HIP along with its Specialty Stainless Steel Processes (S3P) and Ion Implantation services in Europe. For Bodycote, the benefits of MedAccred to the supplier are evident. The process provides for consistent and standardised critical process audits which result in fewer redundant onsite audits by multiple OEMs and first tier customers. The MedAccred certification should reinforce customer confidence in Bodycote as a premier quality provider of heat treating.

Joe Pinto, Executive Vice President and Chief Operating Officer of the Performance Review Institute, the organisation which administers the MedAccred program on behalf of the medical device industry, sent his congratulations to the team at the Bodycote Derby facility: “We are delighted that Bodycote has the honour of becoming the first company to receive an accreditation from MedAccred in Europe. To be the first in anything demonstrates a high level of foresight and commitment to a long term strategy. The MedAccred audit is challenging and in achieving accredited status, Bodycote’s Derby facility has proven it has the capability to meet and exceed the requirements of its medical customers. The entire team should be proud of their success.”

Heat Treating A Critical Process for MedAccred

Synergy Health in Alajuela, Costa Rica has become the first company to receive MedAccred sterilization accreditation, on January 5, 2016.

This follows the successful development of the MedAccred Audit Criteria for Sterilization by the MedAccred Sterilization Task Group (AC8113, AC8113/1 and AC8113/2). The audit criteria include Radiation (Electron Beam and Gamma) and Ethylene Oxide.  The members of the Task Group come from companies including Johnson & Johnson, Philips, Stryker, Baxter Healthcare, Becton, Dickinson & Co., DSM Biotech, Synergy Health and Flex. The Sterilization audit criteria draw from Industry Standards as well as the most common customer specifications.

Wendy Gould, VP Regulatory Affairs & Quality at Synergy Health said “We look forward to making it easier for our customers to do business with us, leveraging the MedAccred program will reduce their costs and improve audit consistency”.

MedAccred is an industry managed supply chain oversight program that bolsters patient safety.  It does this through clarification of requirements and better identifying how they apply to critical processes used in the production of medical devices.

“Achieving MedAccred status is not easy: it is one of the ways in which the medical device manufacturing industry identifies those suppliers capable of providing superior critical process manufacturing to the Device industry. Synergy Health has worked hard to obtain this status and they should be justifiably proud of it,” said Joe Pinto, Executive Vice President and Chief Operating Officer at the Performance Review Institute. “PRI is proud to support continual improvement in the medical device manufacturing industry by helping companies such as Synergy Health be successful and we look forward to continuing to assist the industry moving forward. I would like to add my personal congratulations to everyone at Synergy Health, as the company has been actively involved in the MedAccred program for some time now, and volunteered to pioneer this process. Their positivity and diligence has paid off and I am delighted to award them the first ever MedAccred sterilization certificate.”

Sterilization is just one area for MedAccred: there is also activity in other critical process areas such as Cable and Wire Harness, Heat Treating, Plastics, Printed Circuit Board Assemblies, and Welding.

Benefits of MedAccred:

  • Provides consistent/standardized critical process accreditation accepted by leaders in the Medical Device Industry resulting in fewer redundant onsite audits by multiple OEMs
  • Conducts in-depth critical process audits that are compliant and consistent to accepted industry/technical standards and conducted by Subject Matter Experts
  • Provides greater visibility of the supply chain to all levels and sub-tiers that provide critical processes, consistent with regulatory requirements (e.g. FDA, ISO 13485, MDD, etc.)
  • Improves flow down of OEM requirements to sub-tier suppliers
