<p>A flexible tissue injection catheter (1) is used to accomplish injections at a precisely controlled depth of precisely controlled volumes of a therapeutic or diagnostic agent into an interior body cavity, such as the epicardium or myocardium of the heart. For myocardial injection, depth penetration is controlled by using a catheter that allows the operator to control depth penetration by means of an adjustable needle stop (14) attached to the catheter handle.</p> |
