Endobronchial methods, devices and systems for treating emphysema by creating an airway bypass in a patient's airway including a longitudinal fenestration held open by an airway expander.

Devices, systems, and methods for creating a percutaneous tracheostomy are described herein. A system can include an inflation assembly and a guidewire assembly. The inflation assembly can include an elongated tube, an inflatable member, and a magnetic member. The elongated tube can have a first end, a second end, and can define a lumen. The inflatable member can be coupled to the first end of the elongated tube and can be fluidically coupled to the lumen such that the inflatable member can receive fluid via the lumen. The magnetic member can be coupled to the first end of the elongated tube such that movement of the magnetic member can cause corresponding movement of the first end of the elongated tube. The first end of a guidewire of the guidewire assembly can include a coupling member, the coupling member configured to couple to the inflatable member such that translation of the elongated tube translates the guidewire assembly.

Embodiments of the invention relate to a ventilation device comprising: a. a ventilation tube having proximal and distal ends; and b. an inflatable cuff having a proximal bulge portion and a distal neck portion disposed distal to the bulge portion, the inflatable cuff being mounted around the ventilation tube to define proximal and distal cuff attachment locations which are both fixed on an outer surface of the ventilation tube.

Systems, methods, and devices are disclosed for accurately detecting a position of an endotracheal tube by sensing patient anatomy surrounding the endotracheal tube. Systems of the present disclosure include an endotracheal tube having at least one sensor supported by the endotracheal tube configured to detect surrounding patient anatomy. A signal processing unit can receive data from the sensor and can at least one of (i) identify the detected patient anatomy, for example, vocal cords, (ii) determine a distance between the detected patient anatomy and a known point on the endotracheal tube, and (iii) verify a positioning of the endotracheal tube within a tracheal or esophageal lumen of the patient. In some embodiments, the system can include at least one inflatable component that can extend along an outer surface of the endotracheal tube and support the at least one sensor.

Disclosed is a three-cavity flushable fish mouth laryngeal mask airway catheter, including a cover, the cover is provided with a respiratory chamber for communicating with a respiratory tract and a digestive chamber for communicating with a digestive tract; the digestive chamber is provided with a digestive opening for communicating the digestive chamber and the digestive tract; a peripheral wall of the digestive chamber is tapered from an end away from the digestive opening to the digestive opening; an edge of the digestive opening includes a plurality of protrusions; and the plurality of protrusions are configured to be close to each other due to a squeezing force during a process of inserting the three-cavity flushable fish mouth laryngeal mask airway catheter into a throat to narrow the digestive opening.

A pulmonary secretion clearing airway structure and related airway management system is disclosed that has a double lumen portion which each lumen of the double lumen portion operably secured to an airway management system so that inspiratory fluid (air/oxygen mixtures, with or without added water vapor) is delivered to the distal end of the ventilation catheter through one of the two lumens and expired inspiratory fluid, pulmonary secretions, and pulmonary fluids are removed from the patient through the other lumen. The expiratory fluid pathway preferably includes a secretion collection system for removing the pulmonary secretions and the like from the pathway, thereby improving operation and safety of the system. The airway structure can be a ventilation catheter or a supraglottic airway system such as laryngeal mask and the like.

A method for the management of secretions in an intubated patient by means of an endotracheal tube to which an inflatable cuff is externally associated, includes the steps of inflating the inflatable cuff for isolating the broncho-pulmonary zone of the patient from the external environment, generating a succession of overpressures inside the endotracheal tube in order to induce breathing in the patient, and a step of deflating the inflatable cuff during the generation of one of the overpressures in order to permit a drainage of the secretions generated by the patient along the trachea towards the outside.

A method and apparatus for a medical airway passage device suitable for maintaining an airway for a patient is provided. The medical airway passage device includes a novel coupler device designed to prevent contamination, infection, and unwanted discharge of patient fluids and solids during usage. The coupler includes a locking mechanism configured to lock the coupler to a breathing tube and thus preventing unintentional decoupling of the coupler from the breathing tube. The coupler also includes a self-sealing suction port for removing patient discharges. The coupler further includes a filter for enabling the free flowing passage of airflow but prevention of the flow of patient discharges.

A tracheal tube inserted through the trachea and bronchi of a subject, comprising: a tube body having a through hole on an outer circumferential surface thereof, a bronchial cuff provided on an outer circumferential surface of the tube body and pressing an inner circumferential surface of the bronchus; wherein the bronchial cuff is spaced apart in the axial direction of the tube body and forms a plurality of ventilation spaces; wherein the ventilation spaces are in communication with each other; wherein the through hole communicate with the ventilation space.

An endotracheal tube apparatus with improved deployment and long-term comfort to a patient generally includes a cap mechanism that can direct enriched oxygen towards the patient's lungs while the endotracheal tube apparatus is being inserted in a patient's trachea. Once the endotracheal tube is fully inserted in the trachea, the cap mechanism can be made to redirect the enriched oxygen to inflate an inflatable cuff integrated with the endotracheal tube thereby blocking off the vocal cord region in the patient and stabilizing the endotracheal tube in the trachea. When the cuff is inflated, the cap mechanism can be made to ventilate the patient.
