Abstract
A single segment catheter has a gradually changing flexibility from a distal to a proximal end of the catheter. According to one embodiment the catheter includes a plurality of strands within the catheter tube wall which change in diameter between the distal and proximal ends to achieve a catheter having a more flexible distal end and a continuously changing flexibility along the catheter length with no joints or distinct changes in flexibility.
