Abstract
A catheter for administering a substance into body tissues includes an elongated catheter body that has at least one portion of the length of the catheter body that expands after the catheter is inserted in the patient's body. The portion that expands provides a seal against backflow of the substance along the outer surface of the catheter body and away from the intended treatment area.
