Abstract

The present disclosure includes an endoprosthesis delivery system comprising an elongate member, such as a catheter, an endoprosthesis, a covering member disposed about the endoprosthesis, and at least one flexible element situated between the endoprosthesis and the covering member. The covering member can extend beyond an end of the endoprosthesis. In operation, as the covering member is removed, the flexible element can guide the covering member over the end of the endoprosthesis to prevent entanglement between the end of the endoprosthesis and the covering member.
