摘要：
Disclosed herein are systems comprising: a first medical device comprising: (i) an expandable body configured for location in a saccular aneurysm defined by an inner wall surface of the aneurysm, the expandable body further comprising: a main body further comprising: a proximal neck； a proximal region and a distal region； a distal neck wherein the proximal neck is joined to the proximal region, the proximal region is joined to the distal region, and the distal region is joined to the distal neck； and a wall extending generally continuously through the proximal neck, proximal region, distal region, and distal neck to define an exterior surface of the expandable body and an interior surface of the expandable body, the interior surface defining an interior volume of the expandable body； wherein the expandable body is configured to assume a single lobed shape with expansion； wherein, when expanded, the expandable body is further defined by a first axis and a second axis transverse to the first axis, the first axis extending between the proximal and distal necks； wherein, when expanded, the proximal region and the distal region meet where the expandable body has the largest diameter as measured parallel to the second axis； and wherein, when expanded, the expandable body is configured to reduce the flow of blood into the aneurysm subsequent to the expanded expandable body being located in the biological space； and(ii) a catheter delivery device comprising a longitudinally extending body comprising a proximal end and a distal end generally opposite the proximal end, the distal end of the catheter delivery device being operably coupled with the expandable body； and a second medical device comprising a coiled wire configured for passage through the catheter delivery device and implantation into a saccular aneurysm adjacent to the distal region of the expandable body while a portion of the coiled wire remains in the interior volume of the expandable body. The deployment of th
