ABSTRACT:
A stent for treatment of a body lumen through which a flow is effected on either side of a sphincter, said stent comprising one or more windings and having an inner core substantially covered by an outer core and including a first segment, a second segment, and a connecting member disposed between the segments. When the stent is positioned within a patient's urinary system, the first segment and second segments are located on either side of the external sphincter to inhibit migration of the stent while not interfering with the normal functioning of the sphincter. The outer coating comprises an absorbable material that provides temporary structural support to the stent. After absorption of substantially all the outer coating of the stent, the remaining relatively compliant inner core facilitates easy removal by the patient by pulling a portion of the stent that extends outside the patient's body for this purpose.
