Claim 13:
14. A vascular delivery device comprising:
an inner expandable member;
an outer drug delivery component comprising a drug infusible layer containing a therapeutic agent and being associated with the inner expandable member;
an infusion lumen in fluid communication with the drug infusible layer;
an outer barrier, wherein the outer barrier circumscribes, is mounted around, or is situated about the drug infusible layer; and
a tethering device comprising a guidewire, filament, or thread coupled to a distal end of the inner expandable member, the tethering device configured to:
(a) retract the inner expandable member and the outer drug delivery component into a retracted position by pulling on the guidewire, filament, or thread to prevent the therapeutic agent from being transferred through the outer barrier; and
(b) extend the inner expandable member and the outer drug delivery component into an extended position via pressurization to allow the therapeutic agent to transfer through the outer barrier in response to being compressed against an exterior vessel wall.
