<p>A device (22) for insertion into the heart wall (25) suited for Trans Myocardial Revascularization (TMR) providing means for the delivery from the heart chamber into the heart wall (25) of blood nutrients. The device (22) has a hollow cylindrical body (21) containing a cavity and side ports (23) situated within that cavity. The cavity is in fluid communication with the heart chamber. The side ports (23) are in fluid communication with the heart wall (25). Distal and proximal end regions of the device (22) provide means (65) to secure the device in the heart wall. In addition, a system (36) for the insertion of the device (22) including a tubular body (40) and a needle point (43) is disclosed. A method for TMR includes the steps of displacement of myocardial tissue, or creation of a channel in that tissue, and placement into heart wall (25) of a stent (22) in the space generated by displaced tissue or channel.</p> |
