1. A ureteral stent, comprising:
a retention member having a distal end portion and a proximal end portion, the distal end portion of the retention member defining a first opening configured to receive a guidewire, the retention member having a diameter, the first opening extending along a first axis, the retention member having an external surface on an outer circumference of the retention member, the retention member being coiled at the proximal end portion and uncoiled at the distal end portion; a receiver coupled to the external surface of the retention member, the receiver defining a second opening, the second opening extending along a second axis, the first axis being substantially parallel to the second axis; and a wick member including a strand of material, the wick member extending from the retention member, a proximal end portion of the strand of material being disposed within the second opening of the receiver, the strand of material of the wick member includes a core portion and a sheath coupled to the core portion, the wick member having a diameter, the diameter of the retention member being greater than the diameter of the wick member, wherein the proximal end portion of the strand of material of the wick member is more rigid than the retention member, and a distal end portion of the strand of material of the wick member is less rigid than the retention member. |
