Abstract
A method of treating a hole formed in a catheter includes providing the catheter with an opening formed in a wall of the catheter from an external surface of the catheter to an internal surface of a lumen of the catheter such that the catheter has a sharp external edge formed between the external surface and the opening and a sharp internal edge formed between the opening and the internal surface of the lumen of the catheter. The method additionally includes pushing a proximal end of a mandrel into the opening formed in the wall of the catheter and rounding the sharp external edge of the opening formed in the wall of the catheter with a distal end of the mandrel. The method further includes maintaining the sharp internal edge formed between the opening and the internal surface of the catheter.
