Male urethral stent device
First Claim
1. A medical device for use within a body lumen of a patient, the device comprising:
- a first coil having a plurality of windings defining a first lumen and locatable on the proximal side of the external sphincter, the first coil having a distal end terminating on the proximal side of the external sphincter when the device is placed within the body of the patient;
a second coil having a plurality of windings defining a second lumen and locatable on the distal side of the external sphincter, the second coil having a proximal end terminating on the distal side of the external sphincter when the device is placed within the body of the patient; and
a connecting segment locatable in the external sphincter when the device is placed within the body of the patient, the connecting segment disposed between and coupling together the first and second coils.

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.

16. A medical device for use within a body lumen of a patient, the device comprising:
-
an inner core including a first coil defining a first lumen and having a proximal end and a distal end, a second coil defining a second lumen and having a proximal end and a distal end, and a connecting segment therebetween, the inner core comprising a plurality of spaced coil windings being sized and configured for placement and retention substantially within the urethra of a patient; and
an outer coating layered upon at least a portion of the inner core for supporting the first lumen and the second lumen of the inner core when placed with the body lumen of the patient. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A method of maintaining the patency of a patient'"'"'s urethra, the method comprising the steps of:
-
a. supporting the prostatic section of a the urethra with a first coil defining a first lumen and locatable on the proximal side of the external sphincter;
b. supporting the bulbar section of a the urethra with a second coil defining a second lumen and locatable on the distal side of the external sphincter; and
c. permitting substantially normal constriction of the external sphincter with a substantially uncoiled connecting segment disposed between and coupling the first coil and second coil. - View Dependent Claims (32, 33, 34)
