1. A delivery system comprising:
an implantable medical device releasably attached to the delivery system, the implantable medical device comprising at least one coil at a proximal end of the implantable medical device;
a tubular body defining a longitudinal axis, the tubular body comprising:
a lumen extending therethrough;
a sidewall surrounding the lumen; and
a feature cut from an inner surface of the sidewall and positioned proximally of a distal end of the tubular body, the feature comprising an aperture and directly contacting a proximal-most coil of the at least one coil;
a pull wire extending through the lumen; and
a locking portion of the implantable medical device comprising an opening, the feature positioned within the opening of the locking portion such that a distal portion of the aperture of the feature extends upwards into the opening;
wherein a distal end of the pull wire passes through the distal portion of the aperture of the feature to secure the implantable medical device to the delivery system, and
wherein the feature is bent into a folded configuration and is releasably positioned within the opening of the locking portion such that proximal translation of a distal end of the pull wire causes the feature to resiliently return to a non-folded configuration approximately flush with the inner surface of the lumen.
