Ireland demonstrates high levels of medical technology patent filing per head of population, reflecting the importance of this industry. However, both Switzerland and Israel demonstrate dominance amongst smaller nations, and serving as benchmarks for national planning.

Background and purpose Aspiration is a successful technique used in thrombectomy for acute stroke. It is contingent upon the appropriate position of the aspiration catheter, so that it is in contact with the thrombus. However, navigating the craniocervical vasculature is challenging is some patients. The wedge microcatheter (MicroVention®) is designed to reduce the gap between the microcatheter and the SofiaPlus 6F catheter for ease of advancement. The purpose of this study is to describe our initial experience with the wedge microcatheter. Materials and Methods A retrospective review of 38 consecutive patients in whom the wedge microcatheter was used during thrombectomy was performed to determine whether the wedge microcatheter was successful in delivering the Sofia catheter to the desired location. Results We have found this device to be successful in delivering the aspiration catheter to the correct position in 97% ( N = 37) of cases. It was used predominantly to pass the origin of branching vessels and also to navigate the tortuous cavernous and petrous segments of the ICA. Conclusion The wedge microcatheter is a successful tool in delivering the aspiration catheter to the desired vessel for revascularisation.
