First Claim
1. A prosthesis for insertion into a patient'"'"'s urethra, comprising:
- (a) a first segment including a distal portion and a proximal portion, the distal portion comprising a distal opening, the proximal portion comprising a proximal opening, the first segment defining a lumen extending from the distal opening to the proximal opening;
(b) a second segment connected to the first segment at an inter-segmental distance, the second segment including a distal portion and a proximal portion, the distal portion of the second segment comprising a distal opening, the proximal portion of the second segment comprising a proximal opening, the second segment defining a lumen extending from the distal opening of the second segment to the proximal opening of the second segment; and
(c) a tie connecting the proximal portion of the first segment and the distal portion of the second segment, wherein the tie adopts one of a plurality of configurations in which the tie has one of a plurality of inter-segmental lengths between the first and second segments, positioning the first and second segments at one of a plurality of inter-segmental distances.

Abstract
A urethral prosthesis with prostatic and bulbar segments connected by two types of ties allows the prosthesis to assume at least two configurations different with inter-segmental distances adapted to situations where the patient either has or does not have normal control of the external sphincter. This is particularly useful for a patient undergoing an anesthetic procedure that affects the external sphincter muscles. When the muscles are anesthetized, the prosthesis may provide constant urine voiding, and when the anesthetic effects wear off, the prosthesis may assume a different configuration to allow the sphincter to reassert control over urinary voiding.

37. A method of draining bodily fluid from a patient having an external sphincter situated for voluntary control over drainage of at least one bodily fluid, comprising the steps of:
-
(1) inserting a prosthesis into the urethra of a patient, the prosthesis comprising;
(a) a first segment including a distal portion and a proximal portion, the distal portion comprising a distal opening, the proximal portion comprising a proximal opening, the first segment defining a lumen extending from the distal opening to the proximal opening;
(b) a second segment connected to the first segment at an inter-segmental distance, the second segment including a distal portion and a proximal portion, the distal portion of the second segment comprising a distal opening, the proximal portion of the second segment comprising a proximal opening, the second segment defining a lumen extending from the distal opening of the second segment to the proximal opening of the second segment, and (c) an adjustable tie connecting the proximal portion of the first segment and the distal portion of the second segment; and
(2) adjusting the adjustable tie to adopt the one of a plurality of inter-segmental lengths, thereby positioning the first and second segments at one of a plurality of inter-segmental distances, which allows or disallows insertion of an object between the two segments wherein the insertion intercepts fluid communication between the lumens of the first and second segments, thereby allowing or disallowing voluntary control over drainage of the at least one bodily fluid through the lumens of the two segments. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)

50. A method of draining bodily fluid from a patient having an external sphincter situated for voluntary control over drainage of at least one bodily fluid, comprising the steps of:
-
(1) inserting a prosthesis into the urethra of a patient, the prosthesis comprising;
(a) a first segment including a distal portion and a proximal portion, the distal portion comprising a distal opening, the proximal portion comprising a proximal opening, the first segment defining a lumen extending from the distal opening to the proximal opening;
(b) a second segment connected to the first segment at an inter-segmental distance, the second segment including a distal portion and a proximal portion, the distal portion of the second segment comprising a distal opening, the proximal portion of the second segment comprising a proximal opening, the second segment defining a lumen extending from the distal opening of the second segment to the proximal opening of the second segment;
(c) a first tie engaging the first and the second segments by holding the segments in proximity to allow fluid communication between the lumens of the segments; and
(d) a second tie having a pre-determined inter-segmental length between the first and the second segments;
(2) constantly draining at least one bodily fluid through the lumens of the two segments held by the first tie; and
(3) when voluntary control over fluid drainage is desired, disengaging the first tie such that the first tie no longer affects the inter-segmental distance, thereby relying on the second tie for connecting the two segments at a predetermined inter-segmental distance sufficient for insertion of an object between the two segments to intercept the fluid drainage. - View Dependent Claims (51, 52, 53, 54, 55, 56, 57)
