Patent ID: 8920513

Claim:
A ureteral stent for facilitating drainage from a kidney to a bladder of a patient, comprising: an elongated body including a length sufficient to extend within a ureter from the kidney to the bladder, said elongated body having a proximal end and a distal end, said elongated body having a longitudinal axis extending from the proximal end to the distal end; a coiled, renal segment extending from said proximal end of said elongated body, wherein said coiled, renal segment extends through a first plane extending laterally left or right from said elongated body such that the coiled, renal segment comprises a first coil that turns only in the first plane; a coiled, bladder end segment extending from said distal end of said elongated body, wherein said coiled, bladder end segment extends through a second plane positioned substantially perpendicular to said first plane, wherein said coiled, bladder end segment is positioned anteriorly in relation to said first plane, wherein the coiled, bladder end segment comprises a second coil that turns only in the second plane, wherein said first plane and said second plane are off-set from one another such that said coiled, bladder end segment is not thrown onto the trigone during use and wherein said coiled, bladder end segment has only one coil that coils towards the proximal end; and wherein the first coil coils around a first coil axis and the second coil coils around a second coil axis, wherein the first coil axis and the second coil axis are not parallel to the longitudinal axis.
