Evaluation summary: eighty-seven samples were received for evaluation.The reported event was confirmed on the received samples.A functional test was performed, the samples were tested on the restriction gauge calibration, fifteen cannulas did not presents restriction at the time of insertion nor extraction, and seventy-two cannulas presented a slight restriction at the time of insertion and extraction, all the received inner cannulas were inserted into fixture and according to process instruction, it was observed that the radius was found out of the specification and the distal tips has a deformation.This condition causes difficulty inserting the dic cannula into outer cannula, the deformation condition is present due to the stress created around the gate area during the molding process; this stress is then relieved when the parts are passed through the shrink oven.Additionally, a dimensional test was performed on five of the cannulas that failed on the functional test, these readings are within specification.The molding process was reviewed and it was observed that the deformation condition is present due to the stress created around the gate area during the molding process; as a consequent of use the combination of mold.Information has been added to the database and trends will continue to be monitored.If information is provided in the future, a supplemental report will be issued.
