2 results about "Venous malformation" patented technology

A detachable tip sheathed balloon microcatheter is provided for delivering an embolic agent to a target location for the embolization of an arteriovenous malformation (AVM). The detachable tip sheathed balloon microcatheter including a balloon microcatheter including a first shaft and an inflatable balloon that is coupled to a distal end portion of the first shaft; and a detachable tip assembly that is configured to be detachably coupled to the first shaft of the balloon microcatheter. The detachable tip assembly includes a protective balloon sheath that is coupled to a proximal end portion of the second shaft, wherein when the detachable tip assembly is coupled to the balloon microcatheter, the protective balloon sheath surrounds at least a portion of the inflatable balloon.

This invention discloses an AI-powered intelligent embolization assistance system for arteriovenous malformations of the brain and spinal cord. By integrating an AI-powered intelligent embolization assistance subsystem and an image-guided platform, it matches 3D-DSA angiography images with internally stored hydrodynamic models of different embolization materials to obtain a three-dimensional vascular architecture map of the lesion and surrounding vessels. Through AI calculation, it completes virtual path planning, simulating the embolization path, three-dimensional course, and embolization range. Based on this, it provides real-time navigation of the microcatheter during EVT, intelligently following its path. After the procedure, it re-acquires 3D-DSA angiography images, performs multimodal image fusion, and assesses the embolization status, the three-dimensional relationship with surrounding structures, and potential related complications. This system enables preoperative planning and simulation of the interventional embolization path and range, and real-time navigation, tracking, and assessment of the lesion during the procedure, effectively improving the efficacy of EVT.
