Abstract
A drug delivery apparatus for dispensing a predetermined amount of one or more drugs into a laser created opening in the human body, the apparatus consisting of a laser delivery means such as an optical fiber or fiber bundle, a drug conduit which transfers the one or more drugs, drug solutions or other substances to the distal end of the laser delivery means, and the laser delivery means disposed essentially coaxially with the drug conduit. Laser delivery means is used to create a TMR channel or other opening in the body. Dispensed drug or other substance travels through the drug conduit and emanates from the drug conduit to be delivered into the TMR channel or other laser created opening. Drug is dispensed by manually or automatically activating an electric motor which actuates a piston element. A method of use is also disclosed.
