Abstract

A catheter assembly includes a catheter, a first intra-catheter stiffener element, and a second intra-catheter stiffener element. The catheter includes a first lumen in fluid communication with a first distal opening and a second lumen in fluid communication with a second distal opening. The first intra-catheter stiffener element is configured for disposition through the first lumen such that a distal end thereof extends distally of the first distal opening, the first intra-catheter stiffener element including a first coupler at a proximal end thereof. The second intra-catheter stiffener element is configured for disposition through the second lumen such that a distal end thereof extends distally of the second distal opening, the second intra-catheter stiffener element including a second coupler at a proximal end thereof.
