摘要： The invention refers to a delivery system (2) for implanting a medical device (1), comprising:a delivery catheter (20) having an inner lumen (201), a mandrel (23) received in the inner lumen of the delivery catheter and movable with respect to the delivery catheter, a tethering member (21) comprising a first end (211), a second end (212) and a positive-locking member (213) fixed to the second end (212). For improving automated manufacturing the delivery system further comprises an adapter piece (22, 32, 42) having a longitudinal axis (L) and comprising a proximal end face (221, 321, 421) and a lateral surface (220, 320, 420), wherein the adapter piece forms a fixed connection between a distal end (231) of the mandrel and the first end of the tethering member, wherein the adapter piece, by moving the mandrel with respect to the delivery catheter, is displaceable between a first position within the inner lumen of the delivery catheter and a second position in which the adapter piece is arranged outside of the inner lumen of the delivery catheter, wherein in the first position of the adapter piece the second end of the tethering member runs along the lateral surface of the adapter piece substantially parallel to the longitudinal axis and beyond the proximal end face of the adapter piece such that the positive-locking member adjoins the proximal end face thereby providing a locked connection with the adapter piece. Further, the invention is directed to a respective assembly comprising the medical device (1) and the delivery system (2) as well as to a method for releasing the medical device (1) from the delivery system (2).
