a proximal end comprising a retention feature, where the retention feature comprises a substantially spherical periphery shape, where the proximal end is configured to be located in a kidney of a patient;
a distal end opposite the proximal end; and
a middle portion between the proximal end and the distal end, where the middle portion comprised a conduit for flow of fluid from the proximal end at the kidney to the distal end,
where the substantially spherical periphery shape extends towards the middle portion, wherein the substantially spherical periphery shape comprises a fluid entrance aperture into the substantially spherical periphery shape at a distal end of the substantially spherical periphery shape, and where the fluid entrance aperture is located proximate the middle portion,
where the proximal end is configured to be located in a kidney of a patient, where a distal end of the substantially spherical periphery shape has a fluid entrance aperture into a coiled portion, and wherein the coiled portion forms a substantially closed tube between the fluid entrance aperture and the middle portion.
