Claim:
1. A medical device for occluding a saccular aneurysm, the medical device comprising: a catheter that includes a first cylindrical member that defines a first lumen and a second cylindrical member that defines a second lumen; a compressed, hollow metal structure comprised primarily of gold, wherein the hollow gold structure, when expanded, assumes a generally rounded form, comprises a single lobe having a wall with an interior surface defining a void, and an exterior surface, with an opening in the wall that allows for the passage of fluid from the first lumen into the void, wherein the void of the hollow gold structure and the first lumen of the catheter are fluidly connected; wherein the catheter is dimensioned to deliver fluid from a fluid source at the proximal end through the first lumen and into the void of a hollow gold structure at the distal end; wherein the catheter is dimensioned to allow for the passage of a guidance member, or guide wire, through the second lumen defined by the second cylindrical member, wherein the second lumen passes entirely through the hollow gold structure; wherein the hollow gold structure is folded to form one or more pleats and the pleats are compressed against at least a portion of the catheter; wherein the passage of fluid from the catheter into the void of the compressed hollow gold structure results in expansion of the hollow gold structure; wherein the medical device is configured such that the expanded hollow gold structure and the catheter can be separated; and wherein the expanded hollow gold structure has sufficient rigidity to remain in an expanded state when implanted in vivo in an unsealed configuration.
