Abstract:
A method for preventing dislodgement of a vascular introducer sheath through a vascular incision when the introducer sheath is positioned through the incision with a distal portion extending into the vessel, the method comprising the steps of:inserting an introducer sheath through the incision in the vessel wall so the distal portion of the sheath extends into the vessel, the sheath having a cutout formed therein; rotating an inner tubular member of the introducer sheath to move a retainer into alignment with the cutout to enable the retainer to move from a refracted position to an extended position so the retainer extends radially outwardly with respect to the introducer sheath; introducing a surgical vascular instrument into the introducer sheath; performing a surgical step in a vascular procedure with the surgical instrument; withdrawing the surgical instrument, the retainer preventing proximal movement of the introducer sheath through the vessel incision during withdrawal of the surgical instrument; and rotating the inner tubular member of the introducer sheath to return the retainer to retracted position, the step of rotating moving the retainer out of alignment with the cutout; and removing the introducer sheath from the vessel through the vascular incision.
