Standard Operating Procedure for the Validation of Sterilization Systems in Drug-Eluting Stents and Coated Devices
Purpose: This document outlines the procedures for the validation of Sterilization Systems (EO/Gamma/E-beam) used in the production of drug-eluting stents and coated devices to ensure compliance with regulatory requirements and product safety.
Scope: This SOP applies to all personnel involved in the validation, operation, and maintenance of Sterilization Systems within the production area for coated devices.
Definitions:
- Equipment Validation: A documented process of ensuring that equipment consistently performs according to predetermined specifications.
- DQ: Design Qualification.
- IQ: Installation Qualification.
- OQ: Operational Qualification.
- PQ: Performance Qualification.
- CSV: Computerized System Validation.
Roles:
- Quality Assurance: Oversee validation processes and ensure compliance.
- Validation Team: Execute validation protocols and document results.
- Production Personnel: Operate sterilization systems according to validated procedures.
Lifecycle Procedure:
- Design Qualification (DQ): Define requirements and specifications for the sterilization system.
- Installation Qualification (IQ): Verify that the system is installed according to specifications.
- Operational Qualification (OQ): Assess the performance of the sterilization system under normal operating conditions.
- Performance Qualification (PQ): Validate that the system effectively sterilizes coated devices.
GDP Controls: All personnel must follow Good Documentation Practices (GDP) to ensure accuracy and traceability of validation records.
Acceptance Criteria Governance: Acceptance criteria must align with User Requirements Specifications (URS) and comply with Annex 11 and Annex 15 of the applicable regulations.
Calibration/PM Governance: The sterilization system must undergo regular calibration and preventive maintenance as per the manufacturer’s guidelines and internal SOPs.
Change Control Triggers: Any modification to the sterilization system, process, or materials must be assessed for impact on validation status and require a formal change control process.
Revalidation Triggers and Periodic Review: Revalidation is required every 12 months or whenever a significant change occurs in the system or process.
