Abstract: The deflectable tip catheters can be used with a primary delivery system (e.g., a bronchoscope, endoscope, or other surgical access device) to access a certain target tissue, such as a tumor (e.g., a lung tumor). The primary access device provides initial access and the deflectable tip catheter can be passed through the primary access device to reach the target tissue which is not otherwise accessible by the primary access device. The deflectable tip catheters have an internal bore free of obstructions such that a drug delivery device (e.g., a needle) or a diagnostic tool can be passed therethrough to directly access the target tissue.
