Abstract
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.
