=== Potential DHF Review Outcomes ===
Based on a review of the above DHF documents a potential outcome for the uretral stent acquisition project could involve the following:
# Better explanation of existing design input documents and also better linkage between the design inputs and product specifications.
# Creation of some new test methods for design, incoming and in-process inspections and also include recommendations for the test method validations. Creation of any new DV&V data would be highly unlikely as it could potentially trigger a new submission or a note-to-file to the regulatory agencies.
# Change in raw materials to better grade materials e.g. Switching resin to a USP Class VI biocompatible resin. This would eliminate some on-going testing but require additional upfront one time biocompatibility testing.
# Updating drawings based on results from the FAI data.
# Converting existing Company Y documents into Company X format and identifying potential gaps and streamlining linkage between raw material specifications and inspection procedures.
# Identifying installation, operational and process qualification requirements with the assumption that no additional design verification and validation activities are required based on the fact that the device is currently approved for sale in the US and ROW.
# Recommend activities necessary for completing packaging, labeling, ship testing and shelf-life testing. Stress should be on being able to leverage existing data for shelf-life without changing the regulatory status of the device.
# Company X may want to perform additional biocompatibility testing to create an internal baseline and also update their biocompatibility files.
# Help streamline suppliers for components when switching over from Company Y to Company X. Search for existing Company X suppliers that can supply off the shelf items that Company Y may be sourcing from other vendors / suppliers.
# Identify process improvements that can be rolled into the manufacturing transfer without changing the design and impacting the existing regulatory status for the device e.g. instead of hand mixing pigment to resin use a pre-mixer to control quality of mixing and resulting extrusion or perform the molding and over-molding steps in 1 machine instead of 2 separate molding machines.
