Abstract
A ureteral stent includes an elongate member defining an axis and having a proximal end portion and a distal end portion. A first extension member and a second extension member extend from the proximal end portion and each include a first portion, a second portion, a third portion and an end portion. In an unconstrained configuration, the first portion is arcuate and extends away from the axis, the second portion extends from the first portion in a distal direction, and the third portion extends from the second portion in a direction away from the axis. In the unconstrained configuration, the end portions of the first and second extension members are spaced apart from each other sufficiently, and the first extension member and the second extension member are sufficiently rigid, to collectively help retain at least a portion of the ureteral stent within a bladder of a patient.
