Embodiments of the invention provide a system and method for accessing an internal body region using a catheter. The catheter includes a catheter body and a medication lumen positioned within the catheter body for delivering medication to the internal body region. An inflation lumen is positioned within the catheter body. A balloon is in fluid communication with the inflation lumen, and the balloon is configured to move between a collapsed position and an expanded position as fluid enters the balloon through the inflation lumen. An anchor covers at least a portion of the balloon on an outer surface of the catheter body and includes a movable section with a first retracted position and a second deployed position. Upon inflation of the balloon, the movable section of the anchor moves radially outward from the first contracted position to the second deployed position to secure the catheter in the internal body region.
