Abstract
The present invention provides for the needleless delivery of selected agents to target tissues within a subject body by providing the agents in one or more high-energy jets or streams directed against selected wall or surface regions of such tissues. One general embodiment of the apparatus includes (i) an elongate jacket having (a) proximal and distal ends, (b) a lumen extending between such ends, and (c) a blunt, distal-end face defining one or more outlet ports in fluid communication with the lumen; (ii) an introduction port for feeding such agent(s) into the lumen; and (iii) a pump communicating with a proximal end of the jacket. The pump is operable to generate an increased pressure within the lumen such that an agent introduced therein will be propelled out of the distal outlet port(s), thereby forming respective high-energy, narrow, fluid jets or streams capable of penetrating a selected tissue. In an exemplary use, wherein a patient's heart is treated with an agent for transferring genetic information to the heart tissue, the distal end of the jacket is positioned adjacent a selected region of the heart wall, and high-energy fluid jets are directed thereagainst in a manner effective to penetrate the wall, thereby delivering the agent into the myocardium.
