The lot number associated with this complaint was reviewed and no issues related to the reported condition were identified during manufacturing.The product sample was returned for evaluation and consisted of one catheter inside a generic plastic bag and did not show any signs of use.Visual inspection was performed and no defects were identified.Functional testing included passing a guide wire through both extensions.The wire passed easily through the arterial extension, however did not pass through the hub in the venous lumen.The catheter was cut and revealed that the hub was partially obstructed.Based on the information received, the root cause can be attributed to an excess of solvent applied to the hub during the manufacturing process.A corrective and preventive action (capa) has been initiated to address this issue.
