An intubation assistance device facilitates insertion of an endotracheal tube or a guide wire into a patient's trachea without requiring a laryngoscope. The device includes a curved flexible tubular member that has a proximal portion having a proximal end, a distal portion having a distal end, and a curved portion between the proximal portion and the distal portion. A lumen extends from the proximal end of the tubular member and terminates in the curved portion of the tubular member. The lumen is sized and shaped so that an endotracheal tube and/or a guide wire is axially moveable through the lumen. A ramp is disposed at a distal end of the lumen, and is angled to facilitate insertion of the endotracheal tube and/or guide wire into the patient's trachea. The distal portion of the tubular member includes an esophageal protrusion that is configured to be inserted in the patient's esophagus.

An intubation device utilizes a steerable endotracheal tube guide to position an endotracheal tube at a laryngeal opening, and is also configured for soft tissue retraction to improve visualization of the laryngeal opening. An ETT is positioned within an overtube of intubation device having proximal and distal ends and a flexible tip. The distal end houses a feeder mechanism for displacing the endotracheal tube through the overtube. A hood includes a stem, base, and expandable body and is affixed to the overtube's distal end. The ETT-containing overtube is precisely positioned at a laryngeal opening via positioning effects of body expansion, activation of a tip director, and/or flexible tip articulation. Unhindered visualization of the laryngeal opening is achieved by expansion of the expandable body, pushing soft tissue outwardly and extensibly. An actuation module controls the feeder mechanism as well as the flexible tip to position flexible tip and endotracheal tube.

An endotracheal tube introducer that includes a controller, a flexible tip, and a tube guide. The controller has an actuator and a rotatable bearing. The actuator operably coupled to move the rotatable bearing. The tube guide is operably coupled between the controller and the flexible tip. The flexible tip is operably coupled to the rotatable bearing to move in at least two degrees of freedom responsive to movement of the actuator.

An airway device facilitates the insertion of an ETT into a patient, the delivery of oxygenated air into a patient, an exchange of the pre-inserted ETT in an intubated patient, and an evaluation of the larynx and trachea in an intubated patient, The device comprises an overtube having a mask section attached to a distal portion of the overtube. An inflatable bladder affixed to the mask section includes a shape and surface configured to seamlessly contact the circumference of the elliptical construction of the laryngeal opening. Once the inflatable bladder is positioned adjacent the laryngeal opening enhanced sealing properties are created so that the axis of the airflow entering the device matches the axis of the trachea, allowing for the improved delivery of oxygenated air into the patient's lungs. The specific utilization of the bladder allows for the device to be constructed smaller than a typical airway device, which may more easily facilitate the insertion process. Additionally, the device may provide a seamless transition into endotracheal intubation when necessary.

A laryngeal mask airway device includes an airway tube and a laryngeal mask placed at a distal end of the airway tube. The distal end of the airway tube opens inside the laryngeal mask. The device includes a connector placed at a proximal end of the airway tube. The connector is in fluid communication with the laryngeal mask through the airway tube and is configured to be connected to a ventilation equipment. The device includes a movable element placed in the laryngeal mask and configured to steer a tip of a catheter passing through the airway tube. The device further includes a control element mounted on the proximal end of the airway tube and a motion transmission device operatively connected to the movable element and to the control element to move the movable element and to steer the tip of the catheter by acting on the control element.

An intubating device is provided for use with an endotracheal tube. In some embodiments, the intubating device includes a sheath having a distal end and a proximal end, and the sheath is configured to be introduced into a body cavity. The sheath has a rigid section, and the sheath has a flexible section at the distal end. The flexible section is selectively bendable. A control housing is located at the proximal end. The control housing includes a deflector for selectively bending the flexible section of the sheath. In some embodiments, an intubating device includes a sheath having a malleable first section and a second section that is selectively bendable located at a distal end of the sheath.

A medical supportable variable tracheal tube ventilation device, having a tracheal tube main body having a telescopic length; the tracheal tube main body comprises a telescopic tracheal tube main tube achieved by compressible sections and a variable tracheal tube head coupled to one end of the tracheal tube main tube; the tracheal tube head is made of a material shapable according to different temperatures; the variable tracheal tube head is a compressed cone, and by airflow inflation, the compressed cone of the variable tracheal tube head expands and opens to the cylindrical shape; an outer side of the tracheal tube main body is sleeved with a tracheal tube sealing cuff, and the tracheal tube sealing cuff is disposed proximal to the variable tracheal tube head; another end of the tracheal tube main tube is connected with a tracheal tube connector.

An intubation stylet includes a shaft with a bendable end section having a tip and a camera at the tip for providing an image of a part of the environment of the tip. The stylet includes a control unit for control of the bending motion of the end section. The control unit is adapted to work under at least two operation modes. In a first of the two operation modes the bending motion of the end section is guided automatically by an orientation of the tip. In a second operation mode, the bending motion of the end section is controlled by manual control of a user without an automatically guidance. The control unit is further adapted to operate in the second operation mode when the first operation mode is inactive.

A laryngeal mask includes a housing having a neck part and a head part extending from a first end of the neck part. The head part further includes a sealing face and an opposing face, the sealing face and the opposing face being connected by an enclosing wall extending upwardly from the sealing face. The sealing face has a peripheral seal for forming a seal around a larynx and having an opening arranged to be positioned over a laryngeal opening. An airway tube is positioned within the housing and extends from a second end of the neck part to the opening in the peripheral seal, wherein the head part includes a resiliently deformable portion positioned between the sealing face and the opposing face. The resiliently deformable portion is a deformable portion of the head part. The resiliently deformable portion has a protrusion and protrudes upwardly from the opposing face.
