The application discloses a filter screen, a stent microcatheter system for embolism of intracranial ruptured aneurysm, and relates to the technical field of medical devices, which comprises a catheter body, a balloon and a supporting filter screen; the balloon and the supporting filter screen are arranged on the catheter body at intervals; the two ends of the supporting filter screen are respectively provided with a fixed ring and a moving ring; the fixed ring is sleeved on the catheter body and is fixedly connected with the catheter body; the moving ring is sleeved on the catheter body and is slidably connected with the catheter body; a traction rope is fixedly connected with the moving ring; the traction rope penetrates through the fixed ring and extends outward; a traction ring is fixedly connected with the extending end; and a positioning spring is arranged between the fixed ring and the moving ring. Through the arrangement, the application provides a novel microcatheter system which is reasonable in structure and convenient to adjust; the balloon and the supporting filter screen are arranged in zones, and the temporary blood vessel occlusion and the aneurysm neck protection blocking functions can be realized respectively.

The utility model relates to an aneurysm flow disturbing device, which comprises: a bottom expansion body in the shape of an ellipsoid or a bowl; a top expansion body in the shape of a cylinder or a circular truncated cone; one end of the bottom expansion body is connected with one end of the top expansion body; the end of the bottom expansion body close to the proximal end is concave inward to form a bottom concave part, and a proximal end mark is arranged in the bottom concave part; the end of the top expansion body close to the distal end is concave inward to form a top concave part, and a distal end mark is arranged in the top concave part. Compared with the prior art, the aneurysm flow disturbing device disclosed by the utility model not only can avoid the risk of occlusion of the carrying artery or branch blood vessel, but also can better conform to the aneurysm body, thereby effectively reducing the displacement risk of the aneurysm flow disturbing device after being implanted into the aneurysm cavity. With the healing of the aneurysm, the space-occupying effect is reduced, and the aneurysm neck is avoided to be left.

This application discloses a device and storage medium for auxiliary diagnosis and treatment decision-making for aneurysms. The device includes a processor and a memory, enabling the following operations: segmenting the aneurysm region and the parent artery region based on original three-dimensional vascular images; calculating key morphological parameters of the aneurysm based on the aneurysm region and the parent artery region; determining the aneurysm neck type based on the key morphological parameters, obtaining a neck classification result; dividing the aneurysm region into a main region and sub-regions; calculating three-dimensional spatial geometric parameters between the main region and the sub-regions; and determining the decision result for auxiliary diagnosis and treatment of the aneurysm based on the neck classification result and the three-dimensional spatial geometric parameters. Using the solution of this application, the aneurysm and parent artery can be automatically segmented, key morphological parameters can be accurately calculated, the neck type can be intelligently classified, complex substructures can be analyzed, and treatment suggestions can be output, providing objective and quantitative decision support for clinicians.
