Outsourcing Outlook on Packaging and Sterilization 16226Outsourcing Outlook on Packaging and Sterilization
May 25, 2010
The landscape for medical device sterilization remains much the same as it has been for more than a decade. Ethylene oxide (EtO), radiation (gamma and E-beam), and steam continue to dominate the sterilization industry, followed by hydrogen peroxide, hydrogen peroxide-plasma, and dry heat. In addition, alternative technologies such as bright light and ozone are under development but are not yet widely accepted.
When choosing an outsourcing partner, OEMs should understand both the advantages and disadvantages of these methods. For example, EtO is a complex process with extended processing times; radiation and steam have material-compatibility limitations; and hydrogen peroxide has difficulty penetrating interior spaces. They should also consider the sterilization method for a device early in the design cycle because available technologies will depend on device materials and designs. To that end, the development team should continually evaluate whether a material or design feature will prevent the use of a particular sterilization method. Without such a review, the OEM may design a product that cannot be sterilized using existing methods, resulting in costly and time-consuming design changes.
In addition to product sterilization, medical device OEMs should also be familiar with the changing field of sterile packaging. Although effective sterile barrier packaging materials have been available for years, packaging manufacturers are continuing to improve and expand their offerings to include thinner, stronger films that reduce material costs and weight, and bonding systems that provide clear visual evidence of seal quality.
Packaging suppliers are not required to maintain quality systems, but they must validate their processes to produce sealed packages. OEMs must be aware of potential vendors' quality systems and perform their own in-house validation of final closure seals. Since such validations can be expensive and time consuming, the OEM should look for suppliers who will support the validation process by providing protocols and technical support.

Service Provider Specializes in E-Beam Sterilization Services
Using ionizing energy from accelerated electrons as its sole sterilization source, a contract manufacturer provides E-beam medical device sterilization services for large and small product configurations and virtually any shipment size. The company offers a range of consulting and product testing services to assist customers in validating and maintaining validation in the E-beam sterilization environment as well. Among its services are engineering and feasibility studies, specific-dose studies, maximum-dose studies, verification dose studies, quarterly dose audits, dose mapping, and cross-linking, which enhances products with commercially valuable physical properties.
Supplier Focuses on Contract EtO Sterilization Services
Specializing in EtO sterilization services, a contract service provider supports the R&D activities of small medical device companies that are in the process of developing new products. Along with the shorter exposure times that typically can be achieved using 100% EtO over mixed gases, performing small and one-off runs lowers EtO exposure times further while minimizing preconditioning times, according to the company. Customers' sterilization processes can also be transferred to larger facilities. As part of its capabilities, the company provides turnkey validation services, including protocol and report preparation, testing management, and project oversight.
