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 vacuum generator, simple design and wide allowable margin of needle travel allow for use in a practitioner's office.

Urethral needle guide device

An improved Luer-lock fitting for hypodermic needles and methods for using the fitting to inject suspended solids into a body. The improved fitting includes a lumen having a curvedly tapered, distally decreasing throat region, which is believed to provide improved flow of suspended solids into the hypodermic needles. One fitting includes at least two threads to provide a more secure fitting able to withstand higher injection pressures. Another fitting includes rounded wings better able to withstand jarring by endoscope eyepieces and resisting being dislodged from position. One method includes injecting suspended solids into soft tissue such as sphincter mechanisms. One method includes injecting suspended solids into tissue surrounding a mechanism to correct defects.
