A photograph of the device was provided, and a crack is seen on the y-port.The root cause could not be determined based solely on a photographic evaluation.The manufacturing process of the y-port assembly, tests and inspections were reviewed.They performed leak test following all product specifications.Functional testing and visual inspections are being performed according to the current quality standards and inspection procedures.The analysis performed by the team concluded that the main root cause is related to a workmanship issue for the detached connector.Corrective actions were implemented by installing a new solvent dispenser for a better handling of solvent for the assembly process of the y-port and to improve the structure of the y-port design by eliminating the ¿wing¿ design and replacing it with a ¿no wing¿ design which will increase the surface area of the bond strength for the y-port assembly.
