The invention relates to an implant for the treatment of arteriovenous malformations, in particular aneurysms, in which the implant can be brought into a target site in the vasculature of a patient in a compressed state by means of a microcatheter, and the implant is imparted with a second structure by means of which it assumes an expanded state when released from the microcatheter, wherein the implant is releasably connected to the insertion aid via a separation site, and wherein the implant in the expanded state has a body having a proximal section and a distal section wherein the proximal section and the distal section have a dome-shaped configuration wherein the convex side of the dome of the proximal section is in a proximal direction and the convex side of the dome of the distal section is in a distal direction. The convex side of the dome of the proximal section faces in the distal direction, and wherein the proximal section and the distal section are connected to each other by a plurality of connecting struts. Alternatively, the implant may have the shape of a closed tulip head. The implant according to the invention can effectively adapt to the shape of a corresponding aneurysm.

The invention relates to an implant (1) for the treatment of arteriovenous malformations, in particular aneurysms (2), wherein the implant (1) can be introduced in a compressed state to a destination in the blood vessel system of a patient by means of a microcatheter (3) and a secondary structure is imprinted on the implant (1) by means of which it assumes an expanded state upon release from the microcatheter (3), wherein the implant (1) is detachably connected to an insertion aid (5) via a release point (4) and, in the expanded state, has a base body (6) which is constructed from struts (16), wherein the struts (16) are at least partially connected to one another at intersection points, so that spaces (11) are formed between the struts (16), wherein, in the expanded state, the struts (16) extend radially outwards at the proximal end of the base body (6) and, further along, axially in a distal direction and radially inwards.such that a bulging of the base body (6) results, wherein the base body (6) has a zone at its distal end where the struts (16) are not connected to each other. The implant (1) according to the invention is able to adapt well to the shape of the respective aneurysm (2).

The invention belongs to the technical field of medical treatment, and particularly relates to a treatment system for vein malformation treatment and a use method of the treatment system, and the treatment system comprises a console, a magnetic resonance imaging module, a digital silhouette angiography module, an ultrasonic imaging module, a multi-angle percutaneous puncture module and the like. The venous malformation treatment system integrates the magnetic resonance imaging module, the digital silhouette angiography module, the ultrasonic imaging module and the multi-angle percutaneous puncture module, achieves accurate positioning and efficient treatment, improves puncture accuracy, reduces complications, accurately controls hardener conveying, optimizes the treatment effect and reduces the drug use risk through real-time image guidance, and has good application prospects. Local anesthesia swelling liquid reduces thrombus shedding, protects normal veins, avoids high-value consumable implantation and reduces cost, the system is particularly suitable for children, avoids damage to backflow veins and guarantees safety, and generally, the system remarkably improves the accuracy, safety and economical efficiency of venous malformation treatment and brings better treatment experience to child patients.

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.

Provided herein are methods for the treatment and prevention of vascular lesions arising from RASA1 and / or EPHB4 mutations and associated with capillary malformation-arteriovenous malformation (CM-AVM).
