An automatic wireless medical device release system (100) may reduce the overall diameter of the medical device delivery system. The medical device delivery system (100) includes a medical device (110) with a looped portion (108) at a distal end of the medical device (110). A capture wire (106) is located on a delivery tool that is distal to the medical device. The looped portion (108) of the medical device may be attached to a bend (112) in the capture wire (106). The bend (112) in the capture wire may be maintained by a sheath (114) covering the delivery tool. Removal of the sheath may automatically remove the bend in the capture wire, which may release the looped portion of the medical device (110) from the capture wire (106).
