摘要：
abstract disclosed herein are medical devices comprising a single-lobed, thin-walled, expandable body and a flexible, elongated delivery device for treating vascular saccular aneurysms and occluding segments of blood vessels and other biological conduits. the expandable bodies may include gold and other metals that may be compressed, positioned in the lumen of an aneurysm, or other biological conduit and expanded. the external surface of the expandable bodies can be configured to promote local thrombosis and to promote the growth of tissue into and around the surface in order to reduce migration of the expandable body and to occlude and seal the aneurysm or biological conduit. 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 the exert force on the expandable body to aid in sealing the aneurysm neck. expandable body device and method of use described herein are medical devices consisting of a thin-walled single-lobe expandable body and a flexible elongated delivery device for the treatment of saccular vascular aneurysms and occluding blood vessel segments and other biological conducts. expandable bodies may include gold and other compressible metals, positioned in the lumen of an aneurysm, or other expanded biological conduit.
