Abstract
A ureteral stent includes an elongated tubular member having proximal and distal ends. The proximal end is configured for placement in the bladder and the distal end has a shape of a helical curl including a flex portion which is the second turn of the loop of the helical curl. The flex portion of the loop of the helical curl is positioned at an angle to the body portion between 15-175 degrees to allow for safe removal of the distal end from the kidney.
