Described is a surgical instrument, and method for treating female urinary stress incontinence. The instrument includes a curved needle-like element (10) defining in part a curved shaft (18) having a distal end (17), and a proximal end (19). A tape (12) attaches to the needle (10) for implanting into the lower abdomen of a female to provide support to the urethra. The needle (10) defines an inner lumen (100) for passage of optical devices, and/or fluids. A surgical optical system may interface directly with the needle, or alternatively, the needle hand piece or handle may be modified to accept the optical system. The tip of the needle is also modified to contain a window or viewing port that allows for the transmission of light from the ambient target tissue into the imaging lens of the optical system. The optical system allows the surgeon to maintain continuous anatomic visualization during introduction, and navigation of the needle within the lower abdomen. |
