Abstract: A vascular access catheter is disclosed that has a catheter shaft with a distal end portion with a distal tip having a sloped face that is positioned at an acute angle from the distal tip relative to a longitudinal axis of the catheter shaft. A first, second, and third lumen extend longitudinally through the catheter shaft. The third lumen is configured for receiving a guidewire and may extend a partial length of the catheter or substantially the entire length of the catheter. The first lumen has an aperture located in the angled edge distal end portion of the catheter next to the distal tip and communicates with the first lumen. The second lumen has an aperture that is positioned in the outer surface of the catheter shaft that is in communication with the second lumen, and is spaced proximally from the first lumen aperture. The catheter includes a fluoropolymer additive with specific compositions and/or purity levels.
