Abstract
The present disclosure includes an endoprosthesis delivery system comprising an elongate member, such as a catheter, an endoprosthesis, and an end cap having one or more protrusions extending therefrom. The protrusions may assist in retraction of end cap into an outer sheath, such as an introducer sheath. In some examples, the protrusion includes fins. In some embodiments, the endoprosthesis delivery system further includes a covering member disposed about the endoprosthesis. The protrusions may support the covering member, which may extend beyond the distal end of the endoprosthesis and onto the end cap. In some embodiments, the end cap comprises a tapered profile, which may assist in retraction of the catheter tip and end cap into an outer sheath.
