Received a triple lumen cvc silicone catheter from customer.Upon visual examination, the lumen had a cut/tear approximately 3 inches from the hub.The sample was examined under a microscope and measurements of the lumen profile were taken.The lumen diameters and wall thickness were found to be within specification.A suture was tied around the catheter lumen approximately 3 inches from the hub.The cut in the lumen is just above the suture and is approximately 1/4" long and appears to be a clean cut, not rigged.There is no other visible damage or defects to the catheter.It is possible a sharp was used near the lumen to tie/cut the suture.The catheter showed no signs of degradation and the failure was not due to out of spec product.
