Delivery system aid and associated systems and methods

An endoluminal delivery system, comprising:

• an introducer sheath having a proximal end, a distal end, a lumen extending between the proximal end and the distal end, and a proximal opening at the proximal end providing access to the lumen;
• a delivery catheter configured to be passed through the proximal opening into the lumen of the introducer sheath;
• an endoluminal device releasably maintained along the delivery catheter at a delivery profile that is configured for the endoluminal device to be passed through the proximal opening into the lumen of the introducer sheath while the endoluminal device is maintained in the delivery profile, the endoluminal device having an inner lumen, a first opening providing access to the inner lumen, and a second opening providing access to the inner lumen;
• a plurality of guidewire tubes removably received by the endoluminal device such that the guidewire tubes are removable from the endoluminal device when the endoluminal device is in the delivery profile,
• wherein each of the guidewire tubes passes through the first opening of the endoluminal device into the inner lumen of the endoluminal device and out of the second opening of the endoluminal device,
• wherein each of the guidewire tubes has a first end, a second end, a lumen configured to receive a guidewire, and an enlarged feature configured to selectively prevent insertion of the guidewire tube through the proximal opening of the introducer sheath into the lumen of the introducer sheath.
