Abstract
A stent delivery system delivers a self-expanding stent to a predetermined location in a body lumen. The delivery system has a catheter body, a retractable outer sheath and a proximal retraction handle connected to a proximal end of the catheter body. The catheter body carries the stent near a distal end of the catheter body for transporting the stent for deployment. The sheath surrounds and contains the stent in a delivery configuration where the stent has a reduced radius along its entire axial length. The sheath has an outer tube a separate inner tube. The outer tube has a distal end portion surrounding the stent along its entire length and a proximal end portion connected to the retraction handle. The inner tube is disposed concentrically within the outer tube and has a distal end portion surrounding the stent only along a part of its entire length.
