Patent number: 11911040Abstract: An embolic device for treating aneurysms or other vascular disorders may be more compliant than conventional devices, while still achieving desired porosity. In particular, the device may achieve the desired porosity only at discrete sections along the length of the device where such a porosity is required (e.g., sections that will block the neck of the aneurysm upon deployment). The remaining sections of the device can be configured to increase the device's compliance. For example, the remaining sections can be formed from less material than the sections with the desired porosity. In some instances, the sections with the desired porosity are formed from mesh-screen segments and the remaining sections are formed from coil segments. In some instances, the mesh-screen segments are configured to further enhance the device's compliance. For example, the mesh-screen segment can be formed from a layered structure that achieves greater compliance than conventional braided structures.Type: GrantFiled: June 8, 2021Date of Patent: February 27, 2024Assignee: Arissa Medical, Inc.Inventors: Armando Garza, Be Thi Le, Tae Hee Cho, Regina Coeli Velasco
