The hub design change is specific to the proximal end of the microcatheter.The design and manufacturing of the catheter lumen is not impacted by this design change, therefore initial design verification testing can be leveraged for any catheter lumen specific testing.See Appendix VI & VII of Design Verification Protocol for further details:Assessment of Product Specifications Affected by the Design Change.Additionally, PR08-193A was redlined to include additional visual inspection steps specific to the design change.This redlined copy was signed by both Quality and R&D prior to test execution and technician training.
