Synopsis: Endovascular neurointervention is experiencing a heyday. This is due to technical innovations in imaging, but mainly to the development of new medical devices leading to an increase in the number of endovascular interventions and indications. For acute ischemic stroke, mechanical thrombectomy has become the standard treatment for large vessel occlusions (LVO). Initially limited to a narrow time window of 6-8 hours after symptom onset, the time window has expanded to at least 24 hours if appropriate patient selection by imaging is performed. Distal medium vessel occlusions (DMVO) probably also represent a further indication expansion. However, the range of devices for thrombectomy in small vessels is still limited. The number of studies is also still limited, but there are initial case reports and single centre studies that are promising. Multicentre studies on this topic have begun. However, there is already a special stentriever that can be used to reach very peripheral vessels and perform thrombectomies with a high degree of safety. The radial force of this stentriever can be controlled externally and is therefore particularly safe, as the stress on the vessel wall can be individually adjusted. An adjustable remodeling mesh is based on a similar technology, which can be used as an alternative to balloon assisted coiling in the treatment of aneurysms. For navigation in particularly difficult anatomical conditions, a unique, in situ steerable guidewire can also be used, which is technologically related to the products mentioned above. These technological innovations will be explained in this presentation and illustrated with clinical case studies.
