  • Publication number: 20260041411
    Abstract: Disclosed embodiments include apparatuses, systems, and methods for preventing buckling of an elongated instrument as it is advanced through a channel. In an illustrative embodiment, an apparatus includes an anti-buckling device including at least one movable support bracket. The bracket includes a generally planar member having an inner orifice and an outer edge configured to movably engage an inner surface of a channel. The planar member is configured to provide lateral support to an elongated instrument chosen from one of a needle and a probe responsive to the elongated instrument being motivated through the channel by an actuator. The at least one bracket also includes a positioning member that extends from the planar member. The positioning member is configured to prevent the planar member from twisting within the channel. The positioning member is configured to move relative to a distal end of the actuator so as not to impede movement of the actuator.

  • Publication number: 20250331831
    Abstract: A device and system for allowing real-time viewing of a procedure beyond a distal end of an endoscope. An exemplary device includes a sheath that has at least two lumens and a handle. The handle includes a connector that connects to a proximal end of an endoscope, a shaft portion that rotatably connects to a proximal end of the connector and a manifold that is slidably received by the shaft portion. The manifold connects to the sheath and allows for insertion of a radial ultrasound probe and a medical tool into the sheath. A stopping device in the manifold avoids accidental needle deployment.

  • Publication number: 20240268800
    Abstract: A sampling device insertable into a bronchoscope to obtain samples of target nodules in lungs of a patient, the system can include a sampling needle, a needle inlet guide tube, and a needle actuator. The sampling needle can extend between a base and a tip. The needle inlet guide tube can be removably couplable to the bronchoscope and can define a working lumen. The needle actuator can be configured to receive the base of the sampling needle to extend the sampling needle through the working lumen. The needle actuator can be engageable with the needle inlet guide tube to move the sampling needle through the sampling device. The sampling device can include operating states. In each of the operating states, the needle actuator can move relative to the needle inlet guide tube to move the tip of the sampling needle with respect to the sampling device.
