Abstract

A loading basket is secured at its proximal end to a portion of a delivery device. The stent engages with the interior of the stent basket when loaded onto the delivery device to prevent shifting or movement of the stent during delivery of the stent to a desired location within the bodily lumen. In at least one embodiment, the loading basket has a proximal end, a distal end, and a braided surface. The loading basket comprises a proximal end portion, a proximal transition portion, a body portion, a distal transition portion, a distal end portion, and an angled inward distal end. When loaded onto the delivery device, the outer surface of the stent contacts at least the angled inward distal end of the delivery device and movement of the stent is prevented.
