1. A delivery system for deploying an implantable medical device to a target location of a body vessel, the delivery system comprising:
a handle comprising an aperture, a handle channel, and a handle button;
a tubular body comprising a lumen extending therethrough;
a pull wire extending through the lumen; and
a proximal support tube disposed within the lumen, a distal portion of the proximal support tube comprising a marked distal section covered by the tubular body such that the marked distal section is not visible to an operator of the delivery system, wherein the proximal support tube engages a proximal end of the pull wire such that proximal translation of the proximal support tube causes the pull wire to be translated proximally thereby releasing the implantable medical device from a distal end of the tubular body,
wherein the proximal support tube is inserted into the aperture of the handle, and interacts with the handle button such that proximal movement of the handle button results in proximal translation of the proximal support tube,
wherein at least a proximal portion of a length of the proximal support tube extends through the handle channel,
wherein proximal translation of the proximal support tube and the handle button results in release of the implantable medical device and moves the marked distal section proximally from the lumen of the tubular body into the handle channel so that the marked distal section is visible only when the handle is completely removed from the tubular body and the proximal support tube, and
wherein the handle is completely removed from the tubular body and the proximal support tube after the release of the implantable medical device.
