Male urethral stent device
First Claim
1. A medical device for use within a body lumen of a patient, the device comprising:
- a stent comprising;
a first anchoring segment defining a first passageway, the 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 defining a second passageway, the second anchoring segment disposed on the distal side of the external sphincter when the stent is placed within the body of the patient;
a substantially straight 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;
anda removal segment continuing and extending from the stent and disposed within at least one of the first passageway and the second passageway.

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.

19. A medical device for use within a body lumen of a patient, the device comprising:
-
a stent comprising; a first anchoring segment defining a first lumen, the first anchoring segment disposed on the proximal side of the external sphincter when the stent is placed within the urethra of the patient; a second anchoring segment defining a second lumen, the second anchoring segment disposed on the distal side of the external sphincter when the stent is placed within the urethra of the patient; at least one of the first anchoring segment and the second anchoring segment comprising a coil having a plurality of windings; a substantially straight connecting segment extending through the external sphincter when the stent is placed within the urethra 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 and extending from the stent and including a distal portion disposed outside the body of the patient when the at least one of the first anchoring segment and the second anchoring segment comprising a coil is placed within the urethra of the patient. - View Dependent Claims (20, 21, 22, 23, 24, 25)
