Abstract
Methods and devices for treating female urinary incontinence by injecting bulking material into the female urethral wall. Some devices include a handle, an elongate member attached to the handle, and a vacuum generating syringe removably secured to the handle. The elongate member can include a distal portion projecting distally from the handle, the distal portion having a wide proximal region, a narrowing shoulder, and a narrow distal region. The elongate member can include one or more vacuum ports on either side of the shoulder region. The shoulder can include a distally facing needle aperture allowing passage of a needle for injecting bulking agent. A rotatable connection between the elongate member and the handle facilitates rotatable positioning of the elongate member to permit injection of bulking material at different locations around the urethral wall. In use, the urethral tissue can be pulled to conform against the device elongate member by generating a vacuum through the elongate member ports, inserting the needle through the elongate member and needle aperture, and predictably injecting bulking material inside of and along the immobilized urethral wall. The self contained…
