Abstract

A catheter assembly and related methods directed to stent edge protection for an edge of a stent. One example stent edge protect member is positioned with a distal end portion of the stent edge protect member arranged proximal of and adjacent to a proximal end of the stent. The stent edge protect member defines an outer surface that transitions from an outer surface of the stent at the proximal end of the stent to an outer surface of the catheter branch on which the stent edge protect member is positioned. The stent edge protect member can be positioned on a single catheter branch or multiple catheter branches.
