Abstract: Expandable devices for occluding bifurcation aneurysms are disclosed herein. Several of the embodiments are directed towards an expandable device comprising a mesh configured to be deployed at a treatment site including blood vessel bifurcation of a human patient so that the mesh extends across a neck of an aneurysm and prevents or limits blood flow through the mesh and into the aneurysm. The mesh can comprise one or more circumferentially discontinuous portions so that, when the device is deployed at the treatment site, the device does not substantially impede flow from a parent blood vessel to two or more branching blood vessels. Systems and methods for delivering an expandable device of the present technology are also disclosed herein.
