Vascular expandable devices and associated methods are disclosed herein. An expandable vascular device can include a generally tubular sidewall formed of a plurality of braided strands. The device can have a compressed state for delivery in which the device has a compressed state diameter of 0.027 inches or less. The device can have an expanded state in which the device has an expanded state diameter. A full expansion distance of the device corresponds to a longitudinal unconstrained distance at which the distal end of the expandable device attains the expanded state diameter. The full expansion distance can be 20 mm or less.

Vascular expandable devices

Devices, systems, and methods for treating vascular defects are disclosed herein. One aspect of the present technology, for example, includes an occlusive device comprising a mesh having a low-profile state for intravascular delivery to the aneurysm and a deployed state, the mesh comprising a first end portion, a second end portion, and a length extending between the first and second end portions, and a first lateral edge, a second lateral edge, and a width extending between the first and second lateral edges. The mesh may have a predetermined shape in the deployed state in which (a) the mesh is curved along its width, (b) the mesh is curved along its length, and (c) the mesh has an undulating contour across at least a portion of one or both of its length or its width. The mesh is configured to be positioned within the aneurysm in the deployed state such that the mesh extends over the neck of the aneurysm.

Devices, systems, and methods for the treatment of vascular defects

Vascular expandable devices and associated methods are disclosed herein. An expandable vascular device can be implantable across an aneurysm in a blood vessel of a patient. The device can include a generally tubular structure formed of a plurality of braided metallic elements. The device can have a compressed state with a compressed state diameter of 0.027 inches or less and an expanded state with an expanded state diameter of 1.75 mm or more. Each of the plurality of metallic strands can have an oxide layer having a thickness of about 400 angstroms or less. The tubular structure can be configured to self-expand from the compressed state to the expanded state.
