Abstract:
A method for cannulating an artery, comprising the steps of:providing a slideable cannula comprising an elongate tubular member having a proximal end, a distal end, and a lumen therebetween, the distal end having a preformed angled configuration relative to the proximal end, the slideable cannula further comprising a trocar having a proximal end, a distal end, and a lumen shaped to receive the elongate tubular member; inserting the elongate tubular member into the lumen of the trocar, the trocar maintaining the tubular member in a substantially linear configuration; inserting the trocar through an incision in the aorta; and advancing the distal end of the tubular member beyond the distal end of the trocar into the aorta, wherein the distal end of the tubular member regains its preformed angle configuration.
