Implanted date: device was not implanted.Explanted date: device was not explanted.One catheter was returned for investigation.When we connected a syringe filled with water, then pressed the plunger, leakage was confirmed at the connection between catheter and catheter hub.Upon microscopically checking the leakage portion inverted v-shape damage, which was presumed to have been created by the inner needle while it was being punctured, was observed.The concerned product type is continuously produced by fully automated machine, and an inner needle and a catheter are assembled by one-time operation.If an inner needle contacts to a catheter tube, the inner needle will become exposed outside of the catheter tube, therefore, the automated inspection machine detects such defective product automatically and those are ejected and delivered to the exclusive disposal container.The accuracy and system function are periodically checked to ensure the integrity of our inspection system.When tracing back and reviewed our manufacture inspection records for past six months, defective products, such as a product with an exposed inner needle or scratch on a catheter, were not observed.We have investigated our manufacture inspection records with focusing on the possibility that the inner needle had contacted to the catheter tube during the inner needle and catheter fitting process.However, we were not able to identify the specific root cause.Relevant instructions for use (ifu) reference: "do not attempt to re-insert a partially or a completely withdrawn needle." terumo medical corporation (tmc) (importer) registration no.(b)(4) is submitting this report on behalf of kofu factory of terumo corporation (manufacturer) registration no.(b)(4).
