This invention is 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 (36) 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 (50) to provide a more secure fitting able to withstand higher injection pressures. Another fitting includes rounded wings (54) 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.
L'invention concerne un dispositif Luer lock perfectionné destiné aux aiguilles hypodermiques, et des méthodes d'utilisation dudit dispositif afin d'injecter dans le corps humain des solides en suspension. Ce dispositif perfectionné comprend une lumière (36) possédant une zone d'étranglement conique, distalement décroissante, permettant d'injecter un flux amélioré de solides en suspension dans les aiguilles hypodermiques. Un dispositif, comprenant au moins deux filets (50), constitue un dispositif plus sûr pouvant résister à des pressions d'injection plus élevées. Un autre dispositif, comprenant des ailes arrondies (54), est plus à même de résister aux vibrations causées par les oculaires d'endoscopes, et de rester en position. Une méthode consiste à injecter des solides en suspension dans un tissu mou, par exemple des mécanismes de sphincter. Une autre méthode consiste à injecter des solides en suspension dans un tissu entourant un mécanisme pour en corriger les défauts.
