Performance Qualification Protocol for Stent Coating Machine

Objective: To validate the performance of the Stent Coating Machine to ensure it meets specified requirements for drug-polymer coating application on drug-eluting stents.

Scope: This protocol applies to the Stent Coating Machine used in the R&D and Production areas for the application of drug-polymer coatings on coated devices.

Responsibilities:

  • Validation Team: Responsible for executing and documenting the qualification process.
  • Quality Assurance: Responsible for reviewing and approving the protocol and reports.
  • Operations: Responsible for ensuring the equipment is set up and maintained as per SOPs.

Prerequisites:

  • Completion of Installation Qualification (IQ).
  • Completion of Operational Qualification (OQ).
  • Availability of all necessary materials and equipment for testing.

Equipment Description:

The Stent Coating Machine is designed to apply a uniform drug-polymer coating on stents through spray or dip methods. The critical parameters include coating thickness uniformity, spray parameters, and drying time records.

Test ID Procedure Acceptance Criteria Evidence
PQ-01 Measure coating thickness using a micrometer at various points on the stent. Coating thickness uniformity within ±10% of target. Thickness measurement records.
PQ-02 Record spray parameters during operation (pressure, distance, and angle). Parameters within specified limits as per URS. Spray parameter logs.
PQ-03 Document drying times for coated stents. Drying time within specified limits. Drying time records.

Detailed Test Cases:

  • Test Case PQ-01: Ensure that the coating thickness is uniform across the stent surface by taking measurements at multiple points. Document any variations and assess against acceptance criteria.
  • Test Case PQ-02: During the coating process, monitor and record the spray parameters. Verify that they remain within the defined operational limits.
  • Test Case PQ-03: After coating, measure the drying time and ensure it meets the acceptance criteria. Document any discrepancies.

Deviations: Any deviations from the acceptance criteria must be documented and investigated. A root cause analysis should be performed, and corrective actions should be implemented as necessary.
