Abstract
An example catheter includes a tubular body portion and a cuff. The tubular body portion has a proximal end portion and a distal end portion. The distal end portion defines a distal face of the tubular body portion. The cuff is mounted to the distal end portion and defines a distal face of the cuff. In certain embodiments, the tubular body portion terminates within the cuff such that the distal face of the body portion is positioned proximally of the distal face of the cuff. In certain embodiments, a pocket is formed between the cuff and the body portion. In certain embodiments, the body portion is more rigid than the cuff.
