Investigation summary: two (2) photos were attached for evaluation.Picture one (1) shows an l-70 product.Picture two (2) shows a close-up of the proximal end female luer connector which is observed to have a crack.One (1) unit of part number l-70 was received without original package, in used condition.The sample was visually inspected under normal conditions of illumination to detect any cosmetic issue.A crack was found in the female luer connector.To replicate the failure mode an l-70 device was taken to retest in leak test in order to create damage in the female luer.Leak test was performed 3 times in the l-70 device.During the third attempt the female luer presented damage in the connection part; however, it was not similar to the sample reported.To replicate the failure mode an l-70 device was taken to perform leak test without o ring in the piston in order to create damage in the female luer.Circular damage was created in the connection part of the female luer; however, the crack along the female luer could not be replicated.Based on the replication of the failure mode results the crack reported is not attributable to the manufacturing process.The root cause was not determined.A review of the device history record (dhr) shows there were no observations or nonconformities recorded during manufacture to suggest an issue of this nature would occur with this lot of products.
