摘要：
Devices and methods for treatment of a patients vasculature are described. The device includes a self-expanding resilient permeable shell having a radially constrained state and an expanded state with a globular, axially shortened configuration. The permeable shell may be a single layer of braided elongate filaments having first and second ends that are secured at the proximal end of the permeable shell. The devices may also include permeable shells made of woven braided mesh having a variable mesh density, i.e., the average size of pores in one region are a different than the average size of pores in another region. Methods of using the device to treat a cerebral aneurysm are also described. Methods of forming a tubular braid are also described. Methods of forming a tubular braid with variable braid densities are described. Methods of forming a tubular braid using a castellated mandrel are also described.
