ICI (injectibles). Intracavernousal injection therapy (ICI) is the most effective nonsurgical treatment for ED. Intracavernosal injection therapy has been an effective and reliable ED therapy since 1983. Alprostadil, bi-mix (papaverine and phentolamine), and tri-mix (papaverine, phentolamine, and alprostadil) are all injectable vasodilators used to treat ED.
A Throttle Body Injection (TBI) system has a single throttle body which contains one or two fuel injectors. The injector(s) spray fuel into the intake manifold. TBI systems were used in the late 1980s and early 1990s. In a Multipoint Fuel Injection (MPI) system, each cylinder has its own individual fuel injector. Each injector is mounted on the intake manifold and sprays fuel directly into the intake port for its cylinder.
