Assembly for positioning an embolization coil in the vascular system and a method of introducing a detachable embolization coil
First Claim
1. An assembly for positioning an embolization coil in the vascular system, comprising a delivery wire which in a distal section has a central core and a threading coil fixed to the central core, wherein said threading coil has at least three distal turns arranged with a pitch allowing the embolization coil to be threaded in and out of the threading coil, wherein the central core has a blade-shaped portion that extends inside the threading coil and has a blade thickness, a blade width and edges, said blade thickness being less than the blade width, and wherein the threading coil is fixed to the central core at least at the edges of the blade-shaped portion.
