Abstract
The invention is directed to a device and method for delivering a therapeutic substance to a bodily tissue in a minimally invasive manner. The device includes an elongate flexible tubular member having a proximal end and a distal end. A control means is provided for enabling the distal end of the tubular member to be controllably flexed in a transverse manner for positioning the distal end of the tubular member proximate to the bodily tissue to be treated. A hollow needle is disposed at the distal end of the tubular member for delivering the therapeutic substance into the bodily tissue. A marking means is also included for indicating when a injection has been made in the tissue. The invention is particularly useful for treatment of ischemic heart disease by gene therapy.
