The returned product sample consisted of one palindrome sapphire 28/45kt vt catheter.After visual inspection, a hole could be appreciated on the joint between the catheter and the hub.During underwater test (functional test), bubbles were detected coming out below the hub from lumen which corresponds to the venous extension.The lumen corresponding to the arterial extension did not showed bubbles during the test.All the possible causes were identified.No lot number was provided, therefore, it is not possible to perform a dhr review.This defect has been confirmed.Based on the available information, the probable root cause can be considered as misuse (leak could be caused more likely due to over bending or excessive force).Per procedure, manufacturing performs 100% pressure testing at the final stage of production, which would identify this issue in the catheter assembly.This complaint will be used for tracking and trending purposes.
