Abstract 138: Robotics in Mechanical Thrombectomy. Colombian Feasibility Experience Using the New Adaptive Tiger Device. First in Human Study (FIM)

Purpose The Adaptive Tiger is a novel radially adjustable stent retriever technology for Large Vessel Occlusion (LVO), The unique controllability of adaptive Tiger allows for employing a robotic controller to expand and relax the mesh automatically, using real‐time force measures to react accordingly for maximal encapsulation of the clot, and optimal radial forces during retrieval.The objective of this Registry Study is to evaluate the performance of the new Adaptive Tiger in restoring blood flow in patients with LVO who are ineligible for intravenous tissue plasminogen activator (IV t‐PA) or who fail IV t‐PA therapy. Materials and Methods A novel programmable electro‐mechanical sensor/controller is coupled with a Tigertriever. The sensor/controller automatically executes the operational phases and the optimal opening and closing of mesh throughout each phase. Five patients with AIS and LVO were consented and treated with Robotic Tiger. Results A total of 5 Adaptive Tiger devices were used. All cases with LVO secondary to MCA occlusion. The Adaptive Tiger console operated as intended in all passes. Using force measurements in real‐time and advanced control algorithms, the console expanded the mesh automatically up to wall opposition, executed the active integration technique, and relaxed the mesh for optimal clot retrieval. A final revascularization TICI > 2b‐c, 3 was obtained in all the cases at the end of the procedure. Non‐Major adverse events procedural related were registered in this small series. Conclusion This First ever experience with Robotic Tigertriever demonstrates the feasibility of utilizing robotically‐controlled Tigertriever technology for automatic thrombectomy easily and safely.
