Claim Text:
1. An implantable medical endoprosthesis delivery system, comprising: an outer member including an inner layer, an intermediate layer and an outer layer, wherein the outer member defines a distal end and a length, and wherein the outer layer has a first thickness at a first position proximal of the distal end, a second thickness smaller than the first thickness at a second position closer to the distal end than the first position, the outer layer having a gradual transition region between the first thickness and the second thickness, and a third thickness larger than the second thickness at a third position closer to the distal end than the second position; an inner member at least partially surrounded by the outer member; and wherein the outer member is slidable along the inner member; wherein, the distal end of the outer member is disposed distal to an implantable medical endoprosthesis disposed between a distal portion of the outer and inner members; the second position of the outer layer extends proximal of a proximal end of the implantable medical endoprosthesis; the inner layer of the outer member has a uniform thickness and extends along the length of the outer member; the inner layer defines an inner diameter of the outer member at any position along the outer member; and the outer member defines a first inner diameter and a first outer diameter at the first position of the outer layer, the outer member further defining a second inner diameter and a second outer diameter at the second position of the outer layer, wherein the second inner diameter and the second outer diameter are greater than the first inner diameter and the first outer diameter such that the outer member is flared along the gradual transition region between the first position and the second position.
