Stent kidney curl improvements

A stent comprising:

• a body portion comprising an elongated tubular member, the body portion having a body portion proximate end and a body portion distal end, the tubular member having an axial lumen therein adapted to provide fluid communication from the body portion distal end to the body portion proximal end;
• and
• a kidney curl portion coupled to the body portion distal end, the kidney curl portion comprising a plurality of petals adapted to flare outwardly from the body portion distal end when in a free state.

A ureteral stent for maintaining drainage between a kidney and a bladder comprising:

• a body portion comprising an elongated tubular member, the body portion having a body portion proximate end and a body portion distal end, the tubular member having an axial lumen therein adapted to provide fluid communication from the body portion proximate end to the body portion distal end, the body portion proximate end adapted for placement in the bladder, the body portion adapted for placement in the ureter, and the kidney portion adapted for placement in the kidney.
