A bladder plication system to treat ISD in a patient is provided. The device can include a needle introducer device, and a plication device. The needle introducer device is advanced through the bladder, with the plication device contained and deployable within the needle introducer device. Once inserted in the bladder and positioned, the needle is passed through portions of the bladder wall. The plication device is then deployed through a distal end of the introducer device, wherein the bladder wall is folded near the inner sphincter to reduce forces on the bladder and resolve the patients SUI.
