    摘要： A method of deploying a stent-graft in a curved vessel includes deploying an expandable tip to center a proximal end of the catheter containing a stent-graft in the curved vessel. A sheath is retracted to expose the stent-graft and the stent-graft self-expands into the curved vessel. By centering the catheter containing the stent-graft prior to deployment with the expandable tip, the accuracy of stent graft placement within the curved vessel is improved.

    摘要： A handle sight for a firearm includes a mounting base and a carrying handle. The mounting base has an elongated shape and defining a first end portion and an opposed second end portion, wherein the mounting base is adapted for detachably mounting on the firearm in a reversible orientation to locate the first end portion of the mounting base one of a forward direction and a rearward direction of the firearm. The carrying handle is upwardly extended from the first end portion of the mounting base at a top side thereof, wherein the carrying handle has a hollow structure to define a sight channel for parallelly align with a barrel axis of the firearm so as to enable an operator to aim at a front iron sight of the firearm through the sight channel.
