Apparatus for transporting particles through a patient's trachea into the respiratory system include a delivery tube having at least a ventilation lumen and a particle delivery lumen. The delivery tube has a centering device near its distal tip, such as a balloon eccentrically mounted on the tube to position an outlet of the particle delivery lumen near a centerline of the trachea above the carina branching into the right and left bronchus. A proximal end of the delivery tube connects to a source of particles, and a controller may be provided to adjust a rate and/or an amount of the particles delivered to the patient. In a specific example, frozen particles are delivered to control core body temperature. In other instances, the particle may be a medicament or other substance for effecting other therapies or diagnostic procedures.

A method for designing a cannula for a patient, wherein a processing unit is configured to implement following steps: a) generating a 2D or 3D numerical representation of the trachea of the patient in at least one position, b) identifying a set of anatomical landmarks, c) considering a 2D or 3D numerical representation of a cannula based at least on the landmarks, d) numerically simulating all or a part of an insertion of the cannula into the trachea, e) estimating at least one reciprocal conflict metric between the cannula and the trachea during the insertion, f) changing the cannula when the estimated conflict metric do not meet predetermined conflict criterion, and iterating at least one of the preceding steps until a cannula is found for which the estimated conflict metric meets the predetermined conflict criterion.

A laryngeal mask airway (LMA) intubation guide for use in an endotracheal intubation procedure and in ventilation of a subject, the LMA intubation guide including: an elongate body defining a passageway extending between a proximal opening and a distal opening, for receiving a blade portion of an intubation device; a laryngeal mask at the distal opening, for covering the larynx of the subject; and a ventilation airway extending at least partially along the body, including: a ventilation port at a proximal end of the ventilation airway for connection to a ventilator; and a ventilation aperture at a distal end of the ventilation airway for allowing fluid communication between the ventilation airway and the passageway proximate to the laryngeal mask, the LMA intubation guide being configured to allow intubation of the subject using an endotracheal tube through the passageway, while the subject is ventilated using the ventilation airway.

The present invention relates to endotracheal tubes for intra-operative monitoring of nerve and muscle tissue (neuromonitoring), a system for intra-operative neuromonitoring, a method for deriving stimulus responses in intra-operative neuromonitoring, and a method for classifying tissue types, having the purpose of preventing damage to nerves and muscles which run within the area of operation.

An anesthetized catheter that includes the ability to administer substances and remove substances via the catheter orifice as well as pericatheter with the option of using wireless technology, while also having an indication system.

A pulmonary isolation and ventilation apparatus (e.g., device, system, etc.) is disclosed. The apparatus may include a controller, a steerable outer member (e.g., outer sleeve body), configured to hold an inner member (e.g., endoscope) and a handpiece. The apparatus may be configured as a sleeve for use with any inner member or the apparatus may include the inner member. Through the handpiece, a user may position the outer sleeve body over an endoscope within a target region of the lungs. The position may be verified by the user using a camera of the endoscope. The endoscope may be removed without disrupting the lungs and the positioning within the lungs. The apparatus may provide improved ventilator functionality to the identified region of the lungs through outer member and may provide for isolating a selective targeted area of the lungs for treatment.

Laryngeal mask comprising a dome and a connecting channel configured to produce the artificial ventilation of a patient, wherein the laryngeal mask further comprises an inlet of a gastric aspiration tube, said inlet being located at a distal end of said dome, on the side wall of this dome, wherein said inlet is configured to absorb any gastric secretions from the patient's oesophagus, wherein the laryngeal mask comprises at least a non-return valve located at the distal end of the dome, wherein the valve comprises at least two flexible membranes configured to allow fluid to flow in a single direction from the outside to the inside of the dome, wherein the pipes of the connecting channel connecting the dome with the artificial respirator outside have in their section a geometric configuration classified as an irregular, asymmetric and non-circular polygon.

Nasal tracheal devices include a tube with visual indicia of insertion depth corresponding to patient height and an inflatable cuff. The tube comprises or provides a plurality of lumens that are in fluid isolation including an airpath lumen and a pressurized fluid source for inflating the cuff. The devices may also be configured to suction patient fluid from a location adjacent and/or above the cuff.

The present invention relates to a tracheal ventilation apparatus, in particular a tracheostomy cannula or an endotracheal tube, having a cannula tube, which from a point of view from a gas supply, has a proximal tube portion with a proximal opening and a distal tube portion with a distal opening. In order to provide an easy-to-handle tracheal ventilation apparatus that can easily be inserted and that impedes a swallowing process as little as possible, the proximal tube portion and the distal tube portion are connected to one another by way of an axially air-permeable joint that facilitates at least restricted mobility and, in particular, pivotability of a longitudinal axis of the distal tube portion with respect to a longitudinal axis of the proximal tube portion.

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.
