Ureteral stent
In some embodiments, a ureteral stent includes an elongate member having a first portion and a second portion, which is coupled to the first portion. The first portion of the elongate member is configured to be disposed within a kidney of a patient. The second portion of the elongate member, which has a sidewall that defines a lumen, is configured to deliver fluid from a first location of the sidewall of the second portion to a second location of the sidewall of the second portion via capillary action. The second portion of the elongate member is configured to be disposed within at least one of a bladder and a ureter of the patient.
