For medical device companies, establishing shelf life is not just a regulatory checkbox. It is critical to ensuring that a product remains safe, sterile, and effective from manufacturing to the moment it reaches the patient.
At Pathway, we help innovators plan, execute, and document shelf-life studies that support regulatory submissions and commercialization timelines. Whether a device is in early development or preparing for market clearance, our team works alongside clients to build testing strategies that generate reliable data while keeping development programs moving forward.
Why Shelf-Life Studies Matter
Every medical device labeled with an expiration date must be supported by data demonstrating that the device performs as intended throughout its stated shelf life. This includes confirming that:
- The device continues to function as designed
- Packaging maintains sterile barrier integrity
- Materials do not degrade in a way that impacts safety or performance
For sterile devices in particular, the packaging system must maintain sterility through sterilization, distribution, and storage conditions. These requirements are governed by standards such as ISO 11607 and FDA quality system regulations.
Without sufficient shelf-life data, regulatory submissions can be delayed and commercialization timelines can be impacted.
Accelerated Aging vs. Real-Time Aging
Waiting several years to generate shelf-life data is not practical during product development. Because of this, most shelf-life programs begin with accelerated aging studies.
Accelerated aging simulates the passage of time by exposing products to elevated temperatures in controlled environmental chambers. This process speeds up material degradation so that a product’s long-term stability can be estimated within weeks rather than years.
For example, roughly forty days of testing at elevated temperatures can simulate one year of real-time aging under certain conditions.
However, regulatory bodies typically expect real-time aging studies to run in parallel. These studies confirm the results of accelerated testing over the actual product lifespan.
Testing the Sterile Barrier System
After aging studies are completed, devices and packaging undergo additional testing to confirm they still meet performance requirements. These evaluations often include:
- Seal strength testing
- Dye penetration testing
- Burst testing
- Visual inspection for packaging integrity
These tests help verify that the sterile barrier system remains intact and that the device will arrive at the point of use in the same safe condition in which it was manufactured.
Pathway’s Approach to Shelf-Life Studies
At Pathway, shelf-life testing is not treated as a standalone activity. Instead, it is integrated into the broader development and regulatory strategy for your device.
Our team supports clients by:
- Developing shelf-life study plans aligned with regulatory expectations
- Conducting accelerated aging studies using environmental chambers
- Coordinating real-time aging programs
- Performing sterile barrier and packaging integrity testing
- Generating documentation to support design history files and regulatory submissions
Because Pathway supports design, regulatory strategy, packaging development, and manufacturing, we are able to ensure that shelf-life studies align with the broader product lifecycle.
Supporting MedTech Innovators from Development to Commercialization
Many early-stage device companies underestimate the planning required for shelf-life studies. Establishing protocols, aging samples, and generating data all require careful coordination to avoid delays later in the regulatory process.
By engaging Pathway early, companies can integrate shelf-life testing into their development timeline. This reduces risk and helps ensure the data required for FDA submission and commercialization is ready when it is needed.
Whether your device requires one year, two years, or longer shelf-life validation, Pathway provides the technical expertise and infrastructure needed to generate the data that supports a successful product launch.
