Claim:
1. An occlusion device for occlusion of a body vessel, the occlusion device having a longitudinal axis, the occlusion device comprising: a plurality of outer coiled elements, each outer coiled element having a first proximal end extending distally to a first distal end, each outer coiled element having a first diameter and a first length dimension, the first length dimension being substantially parallel to the longitudinal axis, the plurality of outer coiled elements defining a device body having a proximal device end extending distally to a distal device end and an interior device lumen disposed therethrough, the device body comprising a body outer surface disposed about the interior device lumen wherein each outer coiled element is disposed about the body outer surface, the device body including a device midpoint disposed substantially halfway between the proximal device end and the distal device end; a plurality of inner coiled elements disposed in the interior device lumen, each inner coiled element having a second proximal end extending distally to a second distal end, each inner coiled element having a second length dimension and a second diameter, the second diameter being less than the first diameter of any of the plurality of outer coiled elements; and a proximal cap disposed at the proximal device end, the proximal cap comprising a first interior portion and a first exterior portion, the first proximal ends of the outer coiled elements and the second proximal ends of the inner coiled elements being fixed within the first interior portion of the proximal cap.
