Delivery system for delivering a cardiovascular device

An endovascular delivery system comprising:

• a stent graft including a first end and a second end, the first end including an engagement member, the stent graft configured to change between a radially compressed configuration and a radially deployed configuration, the stent graft includes stent rings and a graft wall;
• a graft cover radially covering at least a portion of the stent graft and configured to retract to uncover the stent graft so that the stent graft changes from the radially compressed configuration to the radially deployed configuration;
• and
• a guide member configured to carry the stent graft and the graft cover, the first end of the stent graft is arranged closer to a proximal end of the guide member than the second end of the stent graft, the guide member securing the first end of the stent graft in a first position where the engagement member is held between the graft cover and the guide member to hold the first end of the stent graft in the first position as the graft cover is retracted to deploy the stent graft, the first end of the stent graft includes a proximal most end contacted by the graft cover in the first position, the guide member includes a proximal end portion and a distal end portion, the distal end portion includes a proximal member, a distal member, and a medial member extending between the proximal member and the distal member, the distal member has a distal member diameter less than a proximal member diameter of the proximal member, and the engagement member contacts the medial member and is spaced apart from the graft cover by the stent graft including the stent rings and the graft wall, the stent graft is radially situated between the graft cover and the engagement member.
