The advancement of technology and the development of smaller treatment instruments has enabled the utilization of neurointerventional procedures to treat conditions affecting small vessels (>2mm). One example is an arteriovenous malformation (AVM), which can be treated by embolization. The embolization procedure is technically challenging and requires extensive training of the physicians. A number of training models have been developed which simulate the treatment of AVM in a flow model with original instruments, using the embolic agent Onyx. These AVM models are frequently intricate and time-consuming to fabricate. This paper presents the simple development of four AVM models for embolization simulations, which have been designed for integration into the existing neurointerventional training simulator, HANNES. The development and testing of the models were carried out by an interdisciplinary team of physicians and engineers. The application test was conducted in a real angiography suite with original treatment instruments and the embolic agent PHIL<sup>TM</sup> by an experienced neurointerventional physician to evaluate the AVM models in regard to geometric mapping, haptics and embolization behaviour. The models offer a range of AVM embolization simulations within the HANNES environment, catering to diverse proficiency levels, from novice to advanced and expert users.
