A single lumen endobronchial tube for selective mechanical ventilation of the lungs can include a medical tube having a single lumen with an opening at each of opposed distal and proximal ends of the tube, the opening at the proximal end of the tube being adapted for connection to an external mechanical ventilation device, and the opening at the distal end of the tube being adapted for delivery of a medical gas; a wall extending throughout the tube's entire length having an internal wall surface, an external wall surface and a thickness therebetween, a portion of the wall having an aperture and a shaft adapted to house a mechanism for sealing the aperture; a distal bronchial cuff positioned along the external wall surface and adapted to expand radially outward; and at least a first proximal tracheal cuff positioned along the external wall surface and adapted to expand radially outward.

A system comprises a flexible instrument, a first user input device spaced from the flexible instrument, and a second user input device including a first state and a second state. The system further comprises a control system configured to, based on an input received from the first user input device, control an orientation of the flexible instrument. The control system is further configured to, based on an input received from the second user input device, adjust a stiffness of the flexible instrument. The stiffness of the flexible instrument is lower when the second user input device is in the first state than when the second user input device is in the second state.

Described is a system (100) and medical device (200) for the electromagnetic tracking of a medical instrument transported through a medical device, the medical device having a central axis (210), a channel (206) that receives and transports a medical instrument through the medical device, the channel extending to a distal portion (202) of the medical device and being in communication with an opening (216) in the medical device that is not aligned with the central axis, the device having a tracking component (220, 224) that is a plurality of coordinated electromagnetic sensors for generating a virtual axis (222) of travel for the medical instrument, with the virtual axis passing through the opening of the device and being aligned with tool insertion axis (206).

A medical system including a flexible instrument such as a lung catheter or bronchoscope provides a control mode in which direct manual control of insertion can be used with computer-assisted control of instrument characteristics such as the orientation or rigidity of a portion of the instrument. To facilitate manual insertion control, a mechanism can provide low inertia and friction for movement along an insertion axis. One implementation employs a manual grip of the instrument for control of insertion pressure, a joystick or other input device for computer-assisted steering, and a foot pedal for control of stiffness or compliance in the instrument. Another implementation employs a joystick for computer-assisted steering and for control of stiffness or compliance in the instrument.

Endoluminal robotic systems and corresponding methods include subsystems for visualization, navigation, pressure sensing, platform compatibility, and user interfaces. The user interfaces may be implemented by one or more of a console, haptics, image fusion, voice controls, remote support, and multi-system controls.

Systems and methods for delivering fluid within a lumen may be provided. For example, a device can include an elongated tubular structure having a central opening through which fluid may flow. The central opening can be defined by an open proximal end and an open distal end. The elongated tubular structure can have an elastic section toward the open distal end. The device can also include a blocking device such as a balloon within the central opening of the elongated tubular structure that can help or be configured to prevent the flow of fluid through the central opening between the open proximal end and the open distal end. The device can further include a balloon disposed on an outer surface of the elongated tubular structure. The balloon can be affixed to the outer surface of the elongated tubular structure at a proximal and/or distal attachment site.

This disclosure concerns systems and methods for tissue volume reduction and control of the flow of substances through the body. Systems according to the various embodiments of the disclosure include check valves formed from wire coils which are deployable through a tubular lumen, such as the working channel of an endoscope, or a catheter.

A surgical system includes a bronchoscope, an extended working channel defining an elongated passageway and adapted to extend through the bronchoscope, and a valve in fluid communication with the passageway of the extended working channel. The surgical system further includes an elongated surgical instrument configured and dimensioned to be inserted through the extended working channel. During operation, a fluid is able to flow from the valve and through the extended working channel such that the fluid travels within an annular area surrounding the elongated surgical instrument positioned within the extended working channel.

A medical suctioning system includes a device for insertion into an intubated patient's bronchi, the device including a controller end having actuating components that include a control mechanism coupled to a plurality of cables at the controller end, the controller end having a suction control button engaged with a plunger to allow for activation and deactivation of suction through the controller end; a control lever in communication with an articulating lever housed within the controller end, the articulating lever to engage with one or more cables disposed through the controller end and to engage with an articulating tip portion at a distal end opposite the controller end; and a catheter extending away from the controller end to the distal end.

A lung isolation system configured for selective isolation and ventilation of the lung in conjunction with a standard endotracheal tube. The system includes an expandable bronchial isolation tube comprising a collapsible nitinol frame, a bifurcated adapter, and a steerable optical stylet.
