Male urethral stent device
First Claim
1. A urethral stent for use within a patient, the stent comprising:
- a first anchoring segment disposed on the proximal side of the external sphincter when the stent is placed within the body of the patient;
a second anchoring segment disposed on the distal side of the external sphincter when the stent is placed within the body of the patient;
a connecting segment extending through the external sphincter when the stent is placed within the body of the patient, the connecting segment disposed between and coupling together the first anchoring segment and the second anchoring segment; and
a removal segment continuing from the first anchoring segment and including a distal portion disposed outside the body of the patient when the first anchoring segment is placed within the body of the patient.

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.
