A lung isolation system configured for selective isolation and ventilation of the lung in conjunction with a standard endotracheal tube. The system includes an expandable bronchial isolation tube comprising a collapsible nitinol frame, a bifurcated adapter, and a steerable optical stylet.

A system includes an endotracheal tube having a plurality of electrodes, wherein the electrodes include at least one stimulating electrode configured to stimulate tissue of a patient and at least one monitoring electrode configured to monitor at least one nerve of a patient. The system includes a nerve integrity monitor device configured to send a stimulation signal to the at least one stimulating electrode to evoke a reflex response, and configured to receive a monitoring signal from the at least one monitoring electrode.

Endotracheal tube stylets and methods of using the same are provided. Aspects of the stylets include an elongated body having a proximal end and a distal end; an expandable member located at the distal end; and a lumen extending from the expandable member to a fluid port positioned at least near the proximal end. The stylets find use in a variety of different applications.

A system for measuring cardiovascular data includes an elongate member having a channel, a first expandable member carried by the elongate member and movable between a collapsed state and an expanded state by adjustment initiated externally of a subject, a first sensor disposed on a surface of the elongate member, second and third sensors disposed on a surface of the first expandable, a first optical sensor located at a first location in relation to the distal end of the elongate member and configured for obtaining photoplethsmographic data, and wherein the first expandable member in its expanded state is configured to interface with the subject's larynx for delivery of at least oxygen gas into the respiratory system of the subject, and the second and third sensors are configured to contact tissue in proximity to the larynx when the first expandable member is in its expanded state.

This invention is an improved assembly for intubation comprising: a cricothyroidotomy tube that can receive a malleable bougie allowing the cricothyroidotomy tube to take the shape of the bougie so that the cricothyroidotomy tube can be placed in a patient. A guide device can receive the bougie so that the bougie can be manipulated with the guide device to assist with insertion of the cricothyroidotomy tube in the patient. A bougie opening can be defined in the guide device for receiving a proximal end of the bougie to position the proximal end out of the way of a care giver to reduce interference that can be caused by the proximal end. Markings on the bougie can illustrate where to positioned the bougie to allow a predetermined amount of the bougie to extend from the cricothyroidotomy tube.

A method for intubation of a patient comprising: providing an LMA and an endotracheal tube, wherein the endotracheal tube comprises a visualization device and wherein the endotracheal tube is adapted for passing through the LMA; positioning the LMA in the patient; and guiding the endotracheal tube with the aid of the visualization device through the LMA for positioning in the trachea of the patient. The method preferably further comprises removing the LMA from the patient following the positioning of the endotracheal tube while leaving the endotracheal tube in position.

The present disclosure describes systems and apparatuses related to a bronchial isolation tube, a laryngeal mask or similar device, and/or adapters and connectors for use with the same, as well as methods for using the same. In an exemplary airway device, the device may comprise a mask portion being defined at a distal end of the airway device, and may be configured and dimensioned to be positioned in a hypopharyngeal area of a patient to cover and seal around a glottis of the patient; and a channel portion extending from a proximal end of the airway device to the mask portion. The channel portion may include first and second channels, wherein the second channel may obliquely merge with the first channel proximate to an opening of the first channel. In an exemplary embodiment, a third channel may form a combined pharyngeal-gastric access channel.

The invention is a laryngeal mask having a head part and an inlet tube, with a passage formed between a laryngeal opening of the head part and an inlet opening of the inlet tube. The laryngeal mask also includes: (1) a covering element encompassing the annular cushion and connected to the outer part of the head part towards the inlet tube from the connection of the annular cushion, where a releasable connection is formed circumferentially in the covering element or at the connection of the head part and the covering element; and (2) a puller element connected to an inner side of the covering element towards the laryngeal opening, and pullable from the inlet tube through the inlet opening, the puller element adapted for removing at least one part of the covering element through the inlet opening of the inlet tube by releasing the releasable connection.

One aspect of the present disclosure relates to a reversible airway device for ventilating a subject. The airway device can comprise a laryngeal tube, an endotracheal tube, and a sealing mechanism. The laryngeal tube can include a tubular guide having a distal end portion, a proximal end portion, and a first passageway extending between the distal and proximal end portions. The laryngeal tube can further include axially spaced apart distal and proximal cuffs coupled thereto. The endotracheal tube can be slidably disposed within the first passageway. The endotracheal tube can have a second passageway that is disposed within the first passageway. The sealing mechanism can be disposed within the first passageway and configured to occlude the flow of gas through the first passageway.

A device for performing a tracheotomy on a patient without the assistance of a medical professional. The device may include one or more mechanical arms that cause a blade to create an incision, cause a dilating tool to dilate the incision, and cause a tracheotomy tube to be inserted into the incision. The device may further include a scanner and/or a hollow needle connected to an air pressure sensor that may be used to detect whether the device is aligned with the patient's airway.
