Until today, the medical product is not available for analysis and could therefore not be studied.Since the device was not returned, the analysis is based on the existing production documents.They did not show any anomalies that could be related to the complaint.All manufacturing steps were carried out correctly.Due to the production process design, it can be assumed that the lead fixation sleeve was mounted to the lead in accordance with the technical specifications.Introducing the lead fixation sleeve into the vascular system is, in our opinion, only possible under increased mechanical pressure during the insertion of the lead into the vascular system, due to the geometry of the lead fixation sleeve.There are no comparable complaints, during which the lead fixation sleeve made its way into the vascular system.Summary: the device complained about was not available for analysis.A check of the production documents did not indicate any manufacturing error.
