A surgical system for use in establishing and maintaining an opening to an anatomical space of a body, the system comprising an obturator assembly having a cutting portion at a distal end and a cannula, the cannula being detachably coupled to the cutting portion and deployable into the anatomical space of a patient, the cannula comprises a locking portion, and a lengthwise extendable body; a valve assembly comprising a passage for receiving the cannula, a first end for coupling to a fluid extraction device and a second end for placement external and adjacent the anatomical space; a base comprising a plate for placement on a patient external and adjacent the anatomical space, the plate has an aperture configured for receiving the obturator assembly and coupling means located about the aperture for coupling with the valve assembly; and wherein, in use, the locking portion of the cannula is configured to be retained in the valve assembly with the extendable body extended into the anatomical space to facilitate a path for fluid extraction, and wherein the cannula comprises means for retaining the cannula in its extended state.

A device, system and method for characterizing a chest drainage apparatus. The device includes a source of both positive pressure and negative pressure, a conduit to provide the positive pressure and the negative pressure to the chest drainage apparatus and a sensor to detect a response of said chest drainage apparatus to either said positive pressure or said negative pressure. The system includes a device that controllably provides either a positive pressure or a negative pressure to the chest drainage apparatus and a sensor to record the effect of the positive pressure or the negative pressure to the drainage apparatus. The method includes the steps of (1) providing a source of both positive pressure and negative pressure; (2) controllably applying either the positive pressure or the negative pressure to the chest drainage apparatus; and (3) detecting a response from the chest drainage apparatus to the pressure application.

An air leak detection system for chest tube collection systems includes a light emitting element, such as an LED, and a photodetector that can detect reflected light emission generated by the light emitting element. The air leak detection system can include a securement component, such as a transparent clip or adhesive, so that the air leak detection system is compatible with any conventional chest tube collection system. In certain embodiments, the light emitting element is positioned closer to the bottom portion of the water seal tube than the photodetector. In certain embodiments, the photodetector is positioned closer to a bottom of the water seal chamber than the light emitting element. In certain embodiments, the air leak detection system is part of a chest tube drainage system. A method of detecting an air leak in a chest tube collection system is also disclosed.

A method and device are provided for simultaneously or near-simultaneously diagnosing and treating tension pneumothorax and/or hemothoraxA Veress-type needle portion includes a hollow needle for puncturing the chest wall over a blunt hollow probe biased by one or more springs to extend distally into the pleural cavity. Openings in the blunt hollow probe connect via a pathway to an automatic check valve, which permits the flow of air and/or fluid only in a proximal direction. Pressure from within the pleural cavity is transmitted to the interior surface of a pressure documenter. If pressure greater than atmospheric pressure is present in the pleural cavity, the pressure documenter will be automatically urged proximally to simultaneously allow air and/or fluid to escape from the pleural space through the device, thus treating the tension pneumothorax and/or hemothorax, as well as providing a stable indicator to positively document the diagnosis of increased pressure.
