Investigation summary: the complaint device was returned for a physical investigation.The engineering and quality engineering department performed a detailed evaluation.The catheter was returned in two pieces, one smaller fragment that remained attached to the port housing with the lock, and the other longer section of catheter.There was evidence of burnishing and bruising on the catheter surfaces near the fractured area, no calcification was present on any surface of the catheters.Both ends of the catheters at the fracture site were oval in shape which could be indicative of pinching/compression.There were puncture marks evident in the septum and it appeared that three of them suture holes were utilized.There were needled marks on the port housing.The catheter lock was received in place.There were no occlusions in the port or in the catheter when flushed.The tubing id and the outlet port od were measured and both were within specification.The instructions for use were reviewed.A potential adverse event/potential risk listed in the ifu is fracture and fragmentation, among other risks.Additionally listed in the ifu warnings: reported complications from repeated subclavian compression include catheter pinch-off syndrome, catheter fracture, and catheter shear followed by embolization of the distal portion.A review of the device history record could not be performed as the lot number was not provided.The device has been discontinued.
