Detachment of a medical device from a delivery assembly can utilize features of electrolytic detachment and features of mechanical detachment. Detachment zones can facilitate mechanical retention of the medical device and electrolytic corrosion of portions of the delivery assembly to allow mechanical release of the medical device. The delivery system comprises: an implant comprising a hub forming an aperture having an aperture cross-sectional dimension; and a delivery wire comprising (i) a core member extended through the aperture and (ii) a stopper positioned in a distal side with respect to the aperture, wherein the stopper has a first cross-sectional dimension larger than the aperture cross-sectional dimension, and the stopper is electrolytically corrodible to reduce the first cross-sectional dimension to a second cross-sectional dimension smaller than the aperture cross-sectional dimension. |
