A device history record (dhr) review was performed and no deviations rated to the reported conditions were identified.A sample was returned for evaluation.The sample consisted of a palindrome that came inside a generic plastic bag and the sample presented signs of use; blood residue.Visual inspection was performed and it revealed that the catheter was cut twice in the shaft.The first is a clean cut and is located in the cuff approximately 5 cm below the hub and the second is an irregular cut located approximately 14 cm below the cuff.Additionally, it was observed that the cuff is in the proper position in the shaft and there are no defects within the glue area identified.The catheter was measured in order to verify that the cuff on the shaft of the catheter was in the correct position.The measurement is within specification.As part of the investigation process, the sample was examined and it was observed that the cuff was loose in some areas; however the glue stayed adhered to the catheter.There is evidence of correct glue application per the sample evaluation.Additionally, this sample shows evidence of prolonged usage and cuff wear, therefore it is concluded that this catheter was used and therefore functioned as intended for approximately 2 months.Based on this investigation, the most possible causes are related to misuse (catheter exposed to excessive force, cleaning agents or jerking motion during use).It must be noted that in-process controls (such as personnel training, incoming quality acceptance testing for raw material, 100% in process visual inspection and visual acceptance sampling) are in place to prevent nonconforming product from leaving the manufacturing operations.This complaint will be used for tracking and trending purposes.
