1. A method of performing a medical procedure, comprising:
- providing a catheter including a first lumen in fluid communication with a first distal opening and a second lumen in fluid communication with a second distal opening;
advancing a distal end of a first intra-catheter stiffener element through the first lumen and out of the first distal opening, the first intra-catheter stiffener element including a first guidewire lumen;
coupling the first intra-catheter stiffener element to the catheter;
advancing a distal end of a second intra-catheter stiffener element through the second lumen and out of the second distal opening, the second intra-catheter stiffener element including a second guidewire lumen;
coupling the second intra-catheter stiffener element to the catheter;
advancing the catheter into a patient;
uncoupling the first intra-catheter stiffener element from the catheter and removing the first intra-catheter stiffener element from the first lumen; and
uncoupling the second intra-catheter stiffener element from the catheter and removing the second intra-catheter stiffener element from the second lumen.
