Device for treating cerebral aneurysms using permeable shells
The patent US12070220B2 describes a novel device designed for the treatment of cerebral aneurysms. The device consists of multiple permeable shells, each featuring a proximal and distal end, and constructed from elongate filaments woven into a mesh. These shells can transition from a radially constrained state for catheter delivery to an expanded state that forms a hollow inner cavity. The device also incorporates coils with inert hydrogel cores that absorb water, connecting the permeable shells to facilitate structural integrity and functionality. The design allows for variations in the diameter of the expanded states of the shells, with the potential for a total of five to nine shells, and an overall length of less than 100 cm.
Additionally, the patent outlines specific configurations for the arrangement and dimensions of the permeable shells and coils. The device can include embolic materials intended for delivery into the aneurysm, enhancing its therapeutic capabilities. The claims detail various arrangements of the shells, including linear configurations and differing diameters, which may optimize the treatment process. The innovative design aims to improve the efficacy of cerebral aneurysm treatments by providing a flexible and adaptable solution that can be tailored to individual patient needs.
