An apparatus for deployment and retrieval of a self-expanding intravascular stent includes an intravascular delivery wire and one or more rings of compliant material fixedly mounted over at least a portion of the intravascular delivery wire. The distal portion of the intravascular delivery wire can be stepped, having a smaller diameter than the proximal portion, and forming a hard stop. Distal and proximal bands can also be provided on the intravascular delivery wire to form hard stops. A self-expanding intravascular stent can release ably retained on the compliant material.
