Abstract:
1. Apparatus suitable for treating a vascular condition, the apparatus comprising: a balloon comprising proximal and distal regions, and further having uninflated and inflated states, wherein an inflation fluid is injectable to contact an inner surface of the balloon in the inflated state, and wherein the balloon is configured to expand and contact at least a portion of the vessel wall in the inflated state; a balloon shaft having proximal and distal ends; a core wire having proximal and distal ends, wherein the proximal region of the balloon is attached to the balloon shaft and the distal region of the balloon is attached to the core wire; a stent configured to be disposed within the balloon, the stent having contracted and expanded states, wherein the stent is configured to engage the inner surface of the balloon in the expanded state, wherein the stent is self-expanding, the apparatus further comprising a stent introducer disposed between the balloon shaft and the core wire, wherein the stent introducer is configured to radially restrain the stent prior to deployment from the contracted to the expanded state; and means for detaching at least a portion of the balloon after the stent expands from the contracted state to leave the portion of the balloon inside the vessel between the stent and an inner wall of the vessel.
