Apparatus and method for treating stress urinary incontinence

A method for treating stress urinary incontinence in a patient, the method comprising:

• inserting a portion of an elongated conduit of a sheath into a urethra of a patient;
• irrigating a bladder of the patient with irrigation fluid from a fluid inflow port of the sheath;
• draining the bladder through a fluid outflow port of the sheath;
• adjusting a position of the portion of the elongated conduit within the urethra until a depth indicator on the elongated conduit aligns with an opening of the urethral meatus of the patient;
• inflating an expandable member in the fossa navicularis of the patient;
• moving an occlusion disc along an outer surface of the elongated conduit until occlusion disc abuts a skin of the urethral meatus;
• and
• injecting a bulking agent through a needle into an external urethral sphincter of the patient.

A delivery system for administering a bulking agent into an external urethral sphincter of a patient, the delivery system comprising:

• an elongated conduit, a connection member connected to a proximal end of the elongated conduit, the connection member including a visualization port configured to receive a portion of a camera unit, a fluid inflow port configured to communicate with an irrigation fluid source, a fluid outflow port configured to communicate with an irrigation fluid reservoir and/or a fluid suction source, and a needle port configured to receive a portion of a needle, the improvement comprising:
• an expandable member disposed on the elongated conduit, the expandable member configured to move between an unexpanded state and an expanded state, and the expandable member configured to seal an interior portion of a urethra of the patient when the expandable member is in the expanded state;
• and
• an occlusion disc slidable along an outer surface of the elongated conduit, the occlusion disc configured to inhibit fluid leakage from the urethra of the patient.
