A system and method for ultrasound-guided placement of a stent are provided. The system includes an echogenic cannula element that may include an echogenically-enhanced cannula that may be embodied as a piercing-tipped needle and/or an echogenically-enhanced stylet, where an echogenically-enhanced cannula element portion is near the distal cannula end. A stent is disposed about the echogenically-enhanced cannula element portion, such that the stent can be navigated to a target site using ultrasound imaging of the echogenically-enhanced cannula element portion.
