Abstract
A medicinal injection instrument for injecting a medicinal medium into a living body includes a tubular arrangement for conducting a medicinal medium to an injection site, the tubular arrangement having a distal end. An ultrasonic oscillator device has an ultrasonic oscillator element juxtaposed to the distal end such that when the instrument is inserted into a living body with the distal end disposed juxtaposed to the injection site, the ultrasonic oscillator element is also disposed juxtaposed to the injection site to thereby enhance diffusion and penetration of the medicinal medium into the body tissue.
