Claim:
1. A stent delivery system comprising: a deployable stent expandable from a compressed configuration to an expanded configuration, the stent having a proximal end portion and a distal end portion; an outer anchoring element having a proximal portion and a distal portion, the outer anchoring element frictionally engaging a radially outer surface of only the proximal end portion of the stent when the outer anchoring element is expanded radially outwardly; an inner anchoring element and an elongate tube within the stent, the inner anchoring element comprising a tube structure having a distal end, wherein the inner anchoring element is at least partially slit in half along an axial length of the inner anchoring element, the distal end being movable from a location within the elongate tube to a location distal to the elongate tube and configured to (i) expand radially outwardly and (ii) frictionally engage an inner surface of the stent in the expanded configuration when removed from within the elongate tube; and a delivery member configured to encapsulate at least partially the stent and the outer anchoring element prior to expanding the stent, wherein the outer anchoring element is configured to expand radially outwardly when moved distally from within the delivery member.
