This mdr was initially sent under number 2245270-2023-00004 on feb 07, 2023.This report require a correction.Correction: the product code and lot number associated with the complaint should be 1261.306, lot 290822gqg.The previous report listed (b)(4), lot # 290922gp erroneously.This complaint is not confirmed.(classification according to sop 002).We received the catheter as a sample.Returned sample consists of 4 parts.Fragment 1 is the surgically removed fragment with a length of 11 cm.Fragment 2 has a length of 15.8 cm snapped by mark 26.4 cm, and fragment 3 has a length of approx.4 cm (last part of catheter tube with bold black mark at the proximal end).Fragment 4 is the extension line and the end of the premicath which has been preserved.Here the customer pulled off a piece to test how hard you must pull it before the line breaks.So, this was done after the incident.If the customer wouldn't have tested it fragment 2 and the remaining catheter fragments would be connected.The proximal end of fragment 1 is filled with blood residues.To dissolve the blood residues the catheter fragment 4 was put in warm water.Afterwards the clotted blood in the wing (pink adapter) was removable.The remaining catheter tube protruding from the pink adapter had a length of 1.5 cm.The microscopic examination of all fracture planes showed rough and uneven surfaces, which is a typical sign for a tensile fracture due to a high tensile load.We have made several images (n=18).Having checked the batch history records, no deviations were found.The batch complied to its specification and was released.Each catheter is flow and leak tested during production.The tensile force of the catheter components is randomly checked.For the involved batch the min value of 1.50 n is requested for the catheter tube and the test reports show values between 4.99 n and 5.98 n with an average value of 5.48 n for the catheter tube.Visual tests and incoming goods inspections are carried out.There are no further complaints for batch 290822gq and eleven further complaints regarding a snapped catheter tube on code 1261.306 within the last three years.No further corrective action was initiated by quality management as there is no hint of a manufacturing fault." no further corrective action was initiated by quality management as there are no indications of a manufacturing fault.".
