1. A method of delivering a therapeutic agent to a depth within the myocardium, said method comprising steps of:

  • providing a tube;

    filling the lumen of the tube with a therapeutic agent by tamping an open end of the tube into a reservoir of therapeutic agent;

    forming the tube into a helical coil;

    covering the tube with a sleeve;

    twisting the helical coil so that it penetrates the endocardium, thereby driving the helical tube into the endocardium; and

    leaving the helical tube implanted in the endocardium and permitting the therapeutic agent to transit from lumen of the helical tube to the endocardium over time.
