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.

Abstract: Various exemplary steerable needles, methods of using steerable needles, and methods of manufacturing steerable needles are provided. In general, a needle configured to be advanced through soft tissue can be configured to be passively steered in a desired direction through the soft tissue. The needle can include a distal tip configured to facilitate the steering. The needle's distal tip can include a beveled or chamfered edge on one side thereof. The distal tip of the needle can be configured to bend relative to a remainder of the needle in a direction opposite to the side of the distal tip that includes the chamfered edge. The soft tissue can provide resistance to the distal tip being advanced therein such that the distal tip automatically bends in a direction away from the chamfered edge. The needle can also include a bendable portion that is proximal to the distal tip.
