The purpose of the DERIVO® 2heal® trial is to conduct a post market clinical follow-up (PMCF) study of the use of the DERIVO® 2heal® Embolisation Device in clinical practice according to EU MDCGs guidance. The DERIVO® 2heal® Study is designed as a prospective, single-arm, multicenter, open-label, national study conducted in Germany with approximately 15 sites planned. The study aims to investigate potential residual risks associated with the use of the device and to update the clinical evaluation of the device in order to ensure the long-term safety and performance of the DERIVO® 2heal® Embolisation Device after its placing on the market. For this purpose, the DERIVO® 2heal® Study will systematically collect information on technical success, safety, and clinical success of treatment of intracranial aneurysms with DERIVO® 2heal® Embolisation Device in clinical practice.~The study duration is expected to be 36 months of enrolment and 12 months follow-up of patients. Up to 158 patients should be enroled at approx. 15 study sites in Germany.~Informed consent will be obtained from all patients prior to implantation of the DERIVO® 2heal® Embolisation Device. In exceptional cases, informed consent may be obtained after the intervention, as the study is purely data collection. It should be noted that the signed informed consent form must be obtained before recording of data in the study and prior any study-specific assessments. Informed consent process will be performed according to ICH-GCP standards. In case of emergency situations when the treatment needs to be performed immediately and informed consent cannot be given prior to the rescue treatment, the informed consent can be obtained retrospectively from the patient or patient's legal representative.~The analysis population will be consist of all patients enrolled who were treated with DERIVO® 2heal® Embolisation device or in whom an attempt of DERIVO® 2heal® Embolisation device implantation was made.~Personal data will be processed in accordance with the relevant national and international legislation and good clinical practice. Data will only be processed for the purpose of the PMCF study. Person-identifiable data will not leave the unit from which they originated, and for pseudonymized data, keys to identification numbers will be held confidentially by the responsible person. Individual patient's medical information will be recorded in the study only in pseudonymized form.~All data in this project are captured in eCRFs and stored into an electronic clinical database. Quality control and data validation procedures such as programmed automatic edit and consistency checks ensure data validity and accuracy immediately at the point of entry into this database. The database application which is used to capture electronic clinical trial data is protected from unauthorized access it is, among other features, access restricted, contains rights and roles functionalities, provides electronic authentication of data entries, maintains an electronic audit trail and provides appropriate data backup functionalities.~After data entry, study monitoring team will perform source data verification and issue monitoring queries directly in the database application.~The database will only be locked after all queries and discrepancies that may have occurred during data entry have been resolved. After database lock, data will be exported in an electronic format and transferred to the responsible biometrician for analysis. The locked database may also be used to generate subject listings and tabulations.~The results of the trial will be reported to the central Ethics Committees after the study was completed. By signing the protocol, the investigator agrees that the results of the clinical investigation may be used for publication. The investigator also agrees that is not permitted to publish any data related to the trial independent of the Sponsor.
