## Abstract

A stent delivery apparatus and/or system including a hollow tubular body with a proximal opening at a proximal end of the hollow tubular body and a distal opening at a distal end of the hollow tubular body. The hollow tubular body can define the proximal opening and the distal opening. A support rod can be passed through the proximal opening and/or the distal opening. The support rod may have a tip, and tip can be olive shaped. A stent may be supported by and/or surround the support rod. The tip of the support rod may also engage with the stent during delivery.
