Abstract
A drainage stent delivery system including a stent, a guide catheter, a push catheter, and an outer sheath. The guide catheter extends through the lumen of the stent and the push catheter is disposed over a portion of the guide catheter proximal of the distal end of the stent. The outer sheath is slidably disposed over the push catheter and surrounding at least a portion of the stent. The outer sheath may be actuated from a first position in which a distal portion of the outer sheath surrounds the stent to a second position in which the distal portion of the outer sheath is proximal of the stent. The stent delivery system may also include a retention mechanism for selectively coupling the stent to the outer sheath which may selectively decouple the stent from the outer sheath through rotational and/or translational motion of the outer sheath relative to the stent.
