Abstract
A method for making a catheter. The method includes forming a catheter tube including an outer wall circumscribing at least one lumen and having a closed distal end, and creating a slit valve in a distal segment of the catheter tube proximal of the closed distal end. The slit valve includes a slit through the outer wall and a compliant segment designed to facilitate inward deflection of a portion of the outer wall along the slit when negative pressure is applied to the at least one lumen. The compliant segment is circumferentially spaced apart from the slit.
