Disclosed is a suction device. The suction device includes a sensor unit configured to measure breathing condition of a patient, a tube unit configured to move into a bronchus of the patient so as to suck foreign material generated in the bronchus of the patient when a measured value measured by the sensor unit exceeds a predetermined reference value, and a control unit configured to control an operation of the tube unit based on the measured value measured by the sensor unit. According to the present invention, there is provided the suction device which is automatically operated by directly determining whether foreign material is generated in the bronchus of the patient.

A system and method enabling the receipt of image data of a patient, identification of one or more locations within the image data depicting symptoms of lung disease, analyzing airways and vasculature proximate the identified locations, planning a pathway to the one or more locations, navigating an extended working channel to one of the locations, identifying the direction of blood flow within vasculature serving the location, positioning a catheter proximate the location, and temporarily isolating a portion of the identified vasculature serving the location depicting symptoms of lung disease.

Methods and systems for administering directed fluidics during a medical procedure for removing an object are disclosed. A method includes inserting first and second medical instruments into a treatment site, providing irrigation and aspiration of the treatment site through the first and second medical instruments, determining a characteristic of one of the irrigation and the aspiration, and selecting a characteristic of the other of the irrigation and aspiration based on the determined characteristic.

Devices, systems for localized delivery of a chemotherapy, hormonal therapy or targeted drug/biologic therapy to a target tissue area of an internal body organ of a patient. A catheter 10 forms a sealed treatment chamber in a natural lumen extending through the target tissue area. Air is purged from the chamber, which is then filled with a liquid drug solution for an adequate treatment session time, solution volume and drug concentration to saturate the target tissue area, thereby providing the treatment. The liquid drug solution may be circulated or recirculated through the chamber or maintained stationary therewithin. The drug may saturate the target tissue area and pass therethrough into the lymphatic system or interstitial space, which may serve as a reservoir of the drug for continued therapeutic treatment after withdrawal of the catheter. The chamber is evacuated at the end of the treatment session.

A method and device for forming a sensor, the method including winding a desired length of wire from a first spool to a second spool, transferring the second spool to a spindle mounted in axial alignment with a substrate, securing the wire to a substrate, rotating the substrate about its axis such that the wire is drawn from the first spool to form a wound region, transferring the second spool to a twist former on which the first spool is mounted, and rotating the first spool and the second spool relative to each other to form a twist pair from the wire.

Methods and apparatus are provided for applying an fragment of a neurotoxin such as the active light chain (LC) of the botulinum toxin (BoNT), such as one of the serotype A, B, C, D, E, F or G botulinum toxins, via permeabilization of targeted cell membranes to enable translocation of the botulinum neurotoxin light chain (BoNT-LC) molecule across the targeted cell membrane to the cell cytosol where a therapeutic response is produced in a mammalian system. The methods and apparatus include use of catheter based delivery systems, non-invasive delivery systems, and transdermal delivery systems.

A dilation device comprises an elongate shaft, an inflatable balloon, and a resilient tube. The inflatable balloon is disposed along the shaft. The resilient tube is also disposed along the shaft and is positioned to encompass at least part of the inflatable balloon. The resilient tube is configured to impose an inwardly directed resilient bias on at least a portion of the exterior of the inflatable balloon. At least part of the resilient tube is secured to one or both of the elongate shaft or the inflatable balloon.

A tube-wall-free right-sided double-lumen bronchial catheter, consisting of a tube-wall-free bronchial catheter body and a double-lumen ventilation catheter body. For the tube-wall-free bronchial catheter body, by means of a plurality of bronchial struts, an upper end is connected to the inner wall of a bronchial cuff and a lower end is connected to an annular opening, and no connection is present among the bronchial struts. When right lung single-lung ventilation is performed, the tube-wall-free bronchial catheter body enters a right main bronchus, the direction and position of the catheter body do not need to be adjusted, the tube-wall-free structure of the tube-wall-free bronchial catheter body can achieve complete opening of the upper lobe of the right lung, and the optimal ventilation effect of the right lung single-lung ventilation is ensured. Poor ventilation of the right upper lung is avoided, time consumption is shortened, airway injuries are reduced, and related complications are reduced.
