A system for delivering a vascular prosthesis, comprising: an elongate body defining a longitudinal axis and comprising a proximal end, a distal end, and a plurality of delivery platforms disposed adjacent the distal end, each of the delivery platforms comprising a recess extending distally of a radial protrusion; a balloon on an outer surface of the elongate body between a distal tip of the distal end and at least one of the delivery platforms; a sheath having a proximal end, a distal end, and a sheath elongate body extending therebetween, the sheath being moveable relative to the elongate body from a first position in which the distal end of the sheath is disposed distally of a distal-most delivery platform to a second position in which the distal end of the sheath is disposed proximally of at least the distal-most delivery platform and the balloon; and a plurality of self-expanding intravascular tacks (10, 10', 10", 140), each intravascular tack being disposed about a corresponding delivery platform; wherein the system is configured to separately place at least two self-expanding intravascular tacks, one at a time, at a treatment zone at spaced apart locations along a vessel wall; and wherein the balloon is configured to be used for post dilation of the at least two placed self-expanding intravascular tacks, the balloon being configured to be positioned, one at a time, within one of the at least two placed self-expanding intravascular tacks and inflated thereby engaging the placed self-expanding intravascular tack with outward pressure from the expanding balloon to enhance placement of the self-expanding intravascular tack at the vessel wall. an elongate body defining a longitudinal axis and comprising a proximal end, a distal end, and a plurality of delivery platforms disposed adjacent the distal end, each of the delivery platforms comprising a recess extending distally of a radial protrusion; a balloon on an outer surface of the elongate body between a distal tip of the distal end and at least one of the delivery platforms; a sheath having a proximal end, a distal end, and a sheath elongate body extending therebetween, the sheath being moveable relative to the elongate body from a first position in which the distal end of the sheath is disposed distally of a distal-most delivery platform to a second position in which the distal end of the sheath is disposed proximally of at least the distal-most delivery platform and the balloon; and a plurality of self-expanding intravascular tacks (10, 10', 10", 140), each intravascular tack being disposed about a corresponding delivery platform; wherein the system is configured to separately place at least two self-expanding intravascular tacks, one at a time, at a treatment zone at spaced apart locations along a vessel wall; and wherein the balloon is configured to be used for post dilation of the at least two placed self-expanding intravascular tacks, the balloon being configured to be positioned, one at a time, within one of the at least two placed self-expanding intravascular tacks and inflated thereby engaging the placed self-expanding intravascular tack with outward pressure from the expanding balloon to enhance placement of the self-expanding intravascular tack at the vessel wall.
