Özet
Introduction: Reliable catheter detachment remains a critical challenge in endovascular embolization, particularly during procedures involving injectable embolic agents, where reflux or prolonged injection may impair mechanical separation. Failure of detachment can result in catheter retention, vessel injury, or embolic complications, underscoring the need for alternative detachment strategies.
Aims: We describe the conceptual design of a novel endovascular embolization catheter module incorporating a predefined electrothermal detachment zone within a hollow, injection-capable catheter
architecture.
Methods: The device integrates an electrolytic conductor routed along the catheter body and terminating at a circumferential detachment zone positioned between a retained distal tip and a retrievable
proximal shaft. Detachment is intended to be achieved through controlled electrothermal activation without mechanical traction.
Results: The proposed design enables separation at a defined intravascular location following embolic delivery, allowing withdrawal of the proximal catheter segment while leaving the distal tip in
situ. Structural features are intended to support compatibility with standard endovascular workflows and commonly used injectable embolic agents.
Conclusion: This design introduces a novel application of electrothermal detachment to an injectioncapable endovascular catheter platform. Although limited to conceptual description, the proposed system provides a framework for future experimental validation and translational development to improve detachment reliability and procedural safety in endovascular embolization.
