Abstract:
1. A stent delivery system comprising: a stent having a proximal end, a distal end, and a lumen extending therethrough; a guide catheter extending through the lumen of the stent; a push catheter disposed over a portion of the guide catheter proximal of the distal end of the stent; an outer sheath slidably disposed over the push catheter and surrounding at least a portion of the stent, the outer sheath being actuatable from a first position in which a distal portion of the outer sheath surrounds at least a portion of the stent to a second position in which the distal portion of the outer sheath is proximal of the proximal end of the stent; and a retention mechanism for selectively coupling the stent to the outer sheath through rotational motion of the outer sheath relative to the stent.
