Title: Designing Effective E&L Studies for Cardiovascular Medical Devices: From Study Planning to Troubleshooting
Presenter: Alexa McLean, Expert Technical Consultant, Nelson Labs
Location: Tech Theatre
Day & Time: Wednesday, October 28th 1:00pm – 1:45pm
Abstract:
Extractables and Leachables (E&L) testing can present unique challenges for cardiovascular medical devices, where complex designs and diverse materials must be considered when developing an appropriate testing strategy. This presentation will explore key elements of E&L study design, including defining study objectives, selecting representative materials and components, establishing appropriate extraction conditions, and developing analytical strategies that generate meaningful and defensible data.
Real-world case studies will illustrate challenges encountered during testing and the troubleshooting approaches used to investigate unexpected findings, analytical issues, and other study complications. Attendees will gain practical insights to help bridge device development with regulatory expectations and improve overall E&L study planning.
