Patent ID: 10610231

Abstract:
Methods for treatment of a cerebral aneurysm within a cerebral vasculature of a patient are described. A microcatheter and a device for treatment of the aneurysm are provided. The device is a self-expanding resilient permeable shell having a plurality of elongate resilient filaments with a woven structure. The plurality of filaments includes small and large filaments. The filaments are bundled and secured to each other at a proximal end. A ratio of the total cross-sectional area of small filaments to the total cross-sectional area of large filaments may be between 0.56 and 1.89. The distal end of the microcatheter is advanced to a region of interest within a cerebral artery. The device is advanced through the lumen and out of the distal end of the microcatheter such that the permeable shell deploys and expands within the cerebral aneurysm. The microcatheter is then withdrawn from the cerebral artery.
