Airway devices, systems, and methods are provided that can achieve ventilation of lungs through a mask that seals around the glottis and connects to a flexible airway channel, while also providing evacuation of gastric and/or pharyngeal body fluid and/or blood during upper airway surgeries or procedures.

An endotracheal tube includes a main tubular portion including a distal end and a proximal end opposite the distal end, the main tubular portion including a central lumen at least in part defined by a wall of the main tubular portion; a wire lumen disposed within the wall of the main tubular portion, the wire lumen defined at least in part by a sidewall portion of the wire lumen and extending from about the proximal end of the main tubular portion to about the distal end of the main tubular portion; a wire disposed in the wire lumen; and one or more cutouts extending along a portion of the wall of the main tubular portion, the cutouts comprising openings in the sidewall portion of the wire lumen, wherein the cutouts are not in fluid communication with the central lumen.

An endotracheal tube with built-in video endoscope function for full-time video monitoring comprises a tubular body and an optical stylet. The tubular body is placed in the trachea of a patient. A front end of the tubular body is connected to a ventilator, and an inflatable bag is provided at a rear end of the tubular body. A primary channel of the tubular body runs through the front and rear ends, so that the ventilator supplies oxygen to the trachea through the primary channel. Each secondary channel of the tubular body includes a front opening located at a side edge of the tubular body and a rear opening arranged at the rear end. The optical stylets run through the secondary channels, respectively. Each optical stylet includes a camera device coupled to a display, which comes out from the rear opening to capture a video in the trachea of the patient.

Oral gas catheters and methods of inducing gas in a patient orally. The oral gas catheter includes one or more delivery cannulas configured to be inserted into the patient's mouth with a distal end of the delivery cannula disposed adjacent the patient's laryngeal inlet, and a clip disposed on the delivery cannula. The clip is configured to secure the delivery cannula to a tooth of the patient. The oral gas catheter may have two such delivery cannulas and clips with the delivery cannulas coupled together by a coupler. The delivery cannulas are placed in an operative position in a patient's mouth and secured in the operative position by releasably securing the clips to the patient's teeth. The oral gas catheter makes it possible to bypass the nasal cavity and deliver oxygen or other gas directly adjacent the laryngeal entrance and into an anatomical dead space of the airway.

A liquid ventilation system includes a reservoir holding a perfluorochemical (“PFC”) fluid, and a suction pump connected to the reservoir to reduce pressure within the reservoir. A sensor is configured to measure an intra-lung pressure. An appliance is configured to be disposed within a patient. The appliance carries an injector to supply the PFC fluid through the appliance. An extraction valve is disposed on an extraction line between the appliance and the reservoir. The extraction valve is arrangeable between a first position enabling fluid communication from the appliance to the reservoir and a second position disabling fluid communication from the appliance to the reservoir.

A method for ventilating the lungs of a patient. The method includes a smart tube for intubation comprising a tip and a cuff. The method also includes one or more cameras, coupled with the smart tube, for providing relative positional intubation measurements of the patient and/or providing intubation images of the patient. Further, the method includes one or more sensors, coupled with the smart tube, for sensing the inflation of the cuff and/or sensing pressure of the cuff. The method for ventilating additionally includes a computing method, coupled with the camera, the at least one sensor and the smart tube, for computing programmed feedback based on the relative positional intubation measurements, and/or the intubation images, and/or the inflation of the cuff, and/or the pressure of the cuff.

An airway management device comprising a body having a proximal end for receiving an oxygen supply tube and an distal end for insertion into a trachea of a patient; said body including a linear portion adjacent to the proximal end and a curved portion adjacent to the distal end; said body including an external shell and having a first bore through said shell for receiving the oxygen supply tube; wherein flexural strength for said airway management device is provided by said shell.

Devices and methods for allowing for improved assisted ventilation of a patient. The methods and devices provide a number of benefits over conventional approaches for assisted ventilation. For example, the methods and devices described herein permit blind insertion of a device that can allow ventilation regardless of whether the device is positioned within a trachea or an esophagus.

Oral airway devices comprising a tubal body formed by a wall which has a length between a distal end and a proximal end, the tubal body being curved into an arch, the wall having two hollow channels which are passages in the tubal body, a first channel and a second channel, wherein the two channels are laterally aligned, wherein the first channel is the passage located peripherally in the tubal body and wherein the second channel is the passage located centrally or substantially centrally in the tubal body and is compatible with a camera insertable and removable from the second channel; and wherein the tubal body does not comprise an endotracheal tube (ETT) lumen.

An endotracheal tube (1) comprises a tubular body (2) having a form of a flexible curved transparent tube with open proximal (3) and distal (4) ends, a connector (7) mounted on the proximal end of the tube and served for attaching a tube cavity to a ventilation device, an inflatable cuff (9) having a cavity, said inflatable cuff fixed hermetically around the distal end of the curved tube and configured to be inflated to seal the cuff against a wall of a patient's trachea and to hold the distal end of the endotracheal tube in the desired position in a patient's larynx, a longitudinal air supply channel (10) in the wall of the tubular body, said channel being in communication with the cavity of the inflatable cuff, a sealed balloon (12) having elastic walls and configured to maintain and monitor pressure in the cuff cavity, the sealed balloon connected to an air supply port, and connected via a catheter (13) to the longitudinal air supply channel to supply an air into the cuff cavity, and a mark (14) made on the surface of the tube from the side of the proximal end at a distance of 2.5-3 cm from the inflatable cuff, wherein the inflatable cuff comprises two layers (15,16), wherein an outer layer (15) of the inflatable cuff is made of a porous biocompatible polymer material and serves as a depot for input and hold the drug in the pores of the polymer material and remove the drug from the pores of the zone of contacting of the cuff with the trachea when the cuff is inflated providing infusion of the drug into the tracheal mucosa.
