RenovaTM detachable aneurysm coiling system offers random, helical and 3D detachable options for endovascular embolization in diameters from 1 to 22 m. It is designed to embolize aneurysms from frame to finish and includes coils shaped specifically to achieve concentric aneurysm filling and coils of large volume to achieve high packing density. Random coiling is the simplest and oldest form of aneurysm coiling technique. It involves the insertion of a single coil or a group of coils into the aneurysm. The coils are usually made of platinum and are thin and tightly coiled to prevent any gaps or spaces from forming in the sac. Helical coiling involves the use of a longer, thin wire that is coiled around itself in a helical manner, forming a spring-like structure. The wire is inserted into the aneurysm in a straightened form, and once inside, it is allowed to coil and expand to fill the aneurysm sac. Helical coils are wider and more closely packed than random coils, thus providing better occlusion of the aneurysm. The 3D coil involves the use of a custom-designed coil, which is made using a computerized imaging process that creates an exact three-dimensional model of the aneurysm. The coil is manufactured to match the exact size and shape of the aneurysm. This type of coil is designed to fit snugly into the aneurysm sac, providing excellent occlusion and reducing the risk of complications. 3D coils are particularly effective in treating aneurysms that are difficult to reach or in fragile blood vessels.
