1. An occlusive device for treating an aneurysm, wherein a neck of the aneurysm opens to a blood vessel, the device comprising:
a mesh having a low-profile state for intravascular delivery to the aneurysm and a deployed state, the mesh comprising—
a distal end, a proximal end, and a length extending between the distal and proximal ends,
a first lateral edge, a second lateral edge, and a width extending between the first and second lateral edges, and
a first side and a second side opposite the first side along a thickness of the mesh, wherein the second side of the mesh is convex,
wherein the mesh is curved along its length and its width;
an embolic element coupled to the proximal end of the mesh at a joint, the embolic element having a proximal end and a distal end; and
a guide positioned between the mesh and the embolic element, the guide having a preset curve along its length configured to orient the mesh relative to the joint such that the first side of the mesh is facing the joint and the second side of the mesh is facing away from the joint, wherein the guide includes a curved portion that includes a turn between about 150 degrees and 210 degrees,
wherein 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 and the embolic element is positioned between the mesh and a dome of the aneurysm.
