Abstract
In some embodiments, a stent includes an elongate member and a distal retention member. The elongate member is configured to be disposed within a ureter of a patient and has a first portion, a second portion and a plurality of beads bonded together. The plurality of beads define a plurality of spaces between the plurality of beads. The plurality of spaces are configured to allow fluid to flow from the first portion of the elongate member to the second portion of the elongate member. The distal retention member is configured to help maintain a portion of the stent within a kidney of the patient.

A stent comprising:
- an elongate member having a first portion, a second portion and a plurality of beads bonded together, the plurality of beads defining a plurality of spaces between the plurality of beads, the plurality of spaces configured to allow fluid to flow from the first portion of the elongate member to the second portion of the elongate member, the elongate member configured to be disposed within a ureter of a patient;
- and
- a distal retention member configured to help maintain a portion of the stent within a kidney of the patient.
