1. A system for filling the biological space of a patient, comprising: a) a metal expandable body, comprising: a distal region； the proximal region, generally located opposite the distal region； an intermediate transition region from the distal region to the proximal region； a central axis extending proximal-distally from the proximal region to the distal region； and a wall extending generally continuously through the intermediate region from the distal region to the proximal region to form the outer surface of the expandable body and the inner surface of the expandable body, the inner surface forming the central volume of the expandable body, wherein the expandable body is expandable from the supplied configuration in advanced configuration； and b) a delivery device comprising: a longitudinally extending body that comprises a proximal end and a distal end generally located opposite the proximal end, wherein the distal end of the delivery device is operatively connected to the proximal region of the expandable body, c) in which, when expandable the body is in the supplied configuration, the wall adopts a corrugated configuration containing many folds folded in a clockwise direction with respect to the central axis, or anti-clockwise rotation with respect to the central axis to form a folded region of the expandable body, d) wherein the delivery device includes a hollow cylindrical element that forms a lumen to allow the passage of fluid from the proximal end of the device1. Система для заполнения биологического пространства пациента, содержащая:a) металлическое расширяемое тело, содержащее: дистальную область； проксимальную область, в общем, расположенную напротив дистальной области； промежуточную область перехода от дистальной области к проксимальной области； центральную ось, проходящую проксимально-дистально от проксимальной области до дистальной области； и стенку, проходящую, в общем, непрерывно через промежуточную область от дистальной области к проксимальной об
