Product reference 4436920 is not cleared for sales in the usa, but it is similar to the product reference 5430425 cleared under #510k130576.Batch history review: we have checked the manufacturing file of the involved batch which complies with our specifications and does not present any discrepancy.No similar complaint has been reported to us on this batch of access ports sold since may 2021.Investigation: despite our requests, either the device nor x-ray pictures were returned for analysis.A sample from our stock has been measured and tested.It complies with our specifications and requirements.Conclusion: without the device, it is not possible to conclude on the root cause of the catheter migration only 3 months after its implantation.This type of incident is a known and well documented potential adverse event of the implantation of access ports.The current complaint rate is low.No corrective action is envisaged.

Note: product reference (b)(4) is not cleared for sales in the usa, but it is similar to the product reference 5430425 cleared under #510k130576.Batch history review: we have checked the manufacturing file of batch nr 36979069 which complies with our specifications and does not present any discrepancy.No other similar complaint was reported to us on this batch of access ports released in may 2021.Investigation results: we received for review two pictures of the explanted catheter: we can see two segments of catheter, probably the distal and the proximal part of the implanted catheter.These pieces of catheter are 5 to 7 cm long.One extermity of the catheter appears flattened.According to the additional information received: -"the device was implanted via subclavian venous access, for which the anesthesiologist performed a subclavian vein puncture using seldinger technique." -"upon admission to the next course of chemotherapy on april 12, 2022, the patient noted a tumor-like mass in the left shoulder joint, limitation of motion and pain in the left shoulder joint.Referred for a chest ct scan.Conclusion: status post implantation of access port system on the right.Violation of integrity of the access port system is detected, namely the tube is ruptured with the distal end identified in the lumen of the trunk and inferior branch of the left pulmonary artery." -" given the short period from catheter implantation to rupture (3 months), no chest x-ray control was performed." conclusion: - the catheter rupture occurred at 5 to 7 cm from the connection.- according to the received information, the catheter was implanted via subclavian vein and the catheter rupture occurred "in shoulder joint" after only 3 months these elements allow us to hypothesis that the catheter was crushed in the costo-clavicular space and repeated squeezing has led to the rupture of the catheter: it is the pinch-off syndrome.Only the examination of the catheter rupture facies and the review of the x-ray pictures could definitively allow us to confirm this hypothesis.The instructions for use warn the physicians against the risk entailed by placing via the subclavian route and give recommendations to avoid the risk of catheter rupture.It is a rare incident (0.01%).No corrective action is envisaged for the moment.
