Advancing Vascular Care: Development of Steerable Microcatheter with Detachable Tip for Liquid Embolization of Vascular Aneurysm: In-vitro Analysis

Abstract Ongoing advancements in vascular intervention are fueled by the pursuit of improved patient outcomes and procedural efficiency. This study presents a newly developed steerable microcatheter tailored for the delivery and retrieval of liquid embolic agents in vascular procedures, specifically targeting the obstruction of blood flow to aneurysms. Key to this research is the incorporation of a biocompatible and embolization tip that can be detached from the steerable microcatheter body using thermoplastic sleeves. This research distinguishes itself by utilizing medical-grade and cost-effective materials, thereby ensuring precise and efficient operation of the technology. In-vitro experiments validate the accuracy and effectiveness of the detachable steerable microcatheter, guaranteeing targeted delivery of embolic agents to the intended vascular site aneurysms. Upon deployment, the tip seamlessly integrates with the liquid embolic fluid, thereby optimizing embolization outcomes.
