摘要：
Disclosed herein are medical devices comprising a single-lobed, thin-walled, expandable body and a flexible, elongated delivery device for treating saccular vascular aneurysms and occluding segments of blood vessels and other biological conduits. The expandable bodies include inter alia a catherter delivery device and a detachable wire to contact the exterior surface of a distal portion of the expanded expandable body, with the detachable wire configured to contact the inner wall surface of the aneurysm opposite the opening to the lumen of the aneurysm where the expandable body entered the lumen of the aneurysm, and wherein, once detached, the detachable wire is configured to remain in the aneurysm. For the treatment of saccular aneurysms, the expandable body may be deployed in combination with one or more coiled wires that contact both the wall of the aneurysm and the expandable body and exert force on the expandable body to aid in sealing the aneurysm neck.
