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.

Claims

1. An apparatus, comprising:

a distal member having a distal end portion, a closed distal end, and a proximal end portion, the distal end portion of the distal member defining an opening, the proximal end portion of the distal member defining an opening, the distal member defining a lumen extending from the opening of the distal end portion of the distal member to the opening of the proximal end portion of the distal member;

a proximal member having a distal end portion and a proximal end portion, the distal end portion of the proximal member defining an opening, the proximal end portion of the proximal member defining an opening, the proximal member defining a lumen extending from the opening of the distal end portion of the proximal member to the opening of the proximal end portion of the proximal member;

a connection member coupled to the proximal end portion of the distal member and the distal end portion of the proximal member, the connection member having a first configuration and a second configuration different than the first configuration, the proximal end portion of the distal member and the distal end portion of the proximal member being separated by a first distance when the connection member is in the first configuration, the proximal end portion of the distal member and the distal end portion of the proximal member being separated by a second distance when the connection member is in the second configuration, the first distance being less than the second distance; and

an actuation thread having a distal end portion and a proximal end portion, the distal end portion of the actuation thread coupled to the connection member, at least a portion of the proximal end portion of the actuation thread being disposed outside of a patient when the distal end portion of the actuation thread is disposed within the patient, the actuation thread configured to move the connection member from the first configuration to the second configuration.

2. The apparatus of claim 1, wherein when the distal member and the proximal member are disposed within the urethra of a patient, the proximal end portion of the distal member and the distal end portion of the proximal member are disposed between a first portion of a urinary sphincter of the patient and a second portion of the urinary sphincter of the patient when the connection member is in its first configuration such that a bodily fluid moves from a first position to a second position, the first position is associated with a portion of the urethra of the patient distal to the urinary sphincter, the second position is associated with a portion of the urethra proximal to the urinary sphincter.

3. The apparatus of claim 1, wherein when the distal member and the proximal member are disposed within a urethra of a patient, the proximal end portion of the distal member is disposed within a portion of the urethra distal to a urinary sphincter of the patient when the connection member is in the second configuration, the distal end portion of the proximal member is disposed within a portion of the urethra proximal to the urinary sphincter of the patient when the connection member is in the second configuration.

4. The apparatus of claim 1, wherein the proximal end portion of the distal member and the distal end portion of the proximal member are in direct contact when the connection member is in its first configuration.

5. The apparatus of claim 1, wherein the second distance is sufficient to permit operation of a urinary sphincter.

6. The apparatus of claim 1, wherein the connection member includes a first tie and a second tie, the first tie is associated with the first configuration of the connection member, the second tie is associated with the second configuration of the connection member, the connection member is configured to move from the first configuration to the second configuration upon disengagement of the first tie.

7. The apparatus of claim 1, wherein the connection member forms at least one loop between the proximal end portion of the distal member and the distal end portion of the proximal member.
