ABSTRACT:
A catheter and stylet assembly comprising an elongate catheter having a lumen open at the proximal and distal ends of the catheter, and a connector adjacent the proximal end of the catheter for connecting the catheter to an extracorporeal support system. A stiff-flexible stylet is provided that is slidably receivable in the lumen of the catheter for providing rigidity to the catheter to facilitate introduction of the catheter into a chamber of a heart or other organ. First and second shoulders are provided on the catheter for abutting a latching portion of the stylet to secure the stylet in either of two positions relative to the catheter. The two positions include a first position wherein the distal end of the stylet extends outwardly from the distal end of the catheter for introducing the catheter into an artery or vein, or directly through the heart wall, and a second position wherein the distal end of the stylet is received within the lumen of the catheter for positioning the catheter in the heart.
