A vascular occlusion device for treating an aneurysm (A), wherein a neck (N) of the aneurysm (A) opens to a blood vessel (V), the device comprising: a proximal portion having a mesh configured to be positioned within the aneurysm (A); a distal portion including a directing region having: a proximal terminus that coincides with a proximal terminus of the distal portion , a distal terminus , wherein the directing region extends along a first direction that runs through the proximal terminus and the distal terminus , and a length measured along the first longitudinal direction between the proximal terminus and the distal terminus ; and a pre-set curved intermediate portion between the proximal and distal portions that, when in a deployed configuration, forms a preset bend in the device that orients the first longitudinal direction of the directing region at an angle of between about 45 degrees and about 135 degrees to a portion of the proximal portion adjacent the intermediate portion , and wherein, when the device is being pushed distally out of a delivery catheter into the aneurysm (A), the directing region directs the distal portion to inhibit the distal portion from exiting the aneurysm (A) through the neck (N) such that the proximal portion crosses the neck (N) and generally remains within the aneurysm (A), and wherein the directing region has a generally linear shape, and wherein the length of the directing region is between about 1.27mm (about 0.05 inches) and about 5.08mm (about 0.20 inches). a proximal portion having a mesh configured to be positioned within the aneurysm (A); a distal portion including a directing region having: a proximal terminus that coincides with a proximal terminus of the distal portion , a distal terminus , wherein the directing region extends along a first direction that runs through the proximal terminus and the distal terminus , and a length measured along the first longitudinal direction between the proximal terminus and the distal terminus ; and a proximal terminus that coincides with a proximal terminus of the distal portion , a distal terminus , wherein the directing region extends along a first direction that runs through the proximal terminus and the distal terminus , and a length measured along the first longitudinal direction between the proximal terminus and the distal terminus ; and a pre-set curved intermediate portion between the proximal and distal portions that, when in a deployed configuration, forms a preset bend in the device that orients the first longitudinal direction of the directing region at an angle of between about 45 degrees and about 135 degrees to a portion of the proximal portion adjacent the intermediate portion , and wherein, when the device is being pushed distally out of a delivery catheter into the aneurysm (A), the directing region directs the distal portion to inhibit the distal portion from exiting the aneurysm (A) through the neck (N) such that the proximal portion crosses the neck (N) and generally remains within the aneurysm (A), and wherein the directing region has a generally linear shape, and wherein the length of the directing region is between about 1.27mm (about 0.05 inches) and about 5.08mm (about 0.20 inches). <EOS>
