摘要:
L'invention se rapporte à un traitement hyperthermique du cancer des poumons, qui consiste à remplir temporairement avec un milieu liquide (110) des passages d'air pulmonaire préalablement sélectionnés (30') jouxtant les tissus pulmonaires qui renferment les cellules malignes (108), à faire circuler un milieu liquide (110) chauffé par ultrasons depuis l'extérieur du corps ou intracorporellement à une température comprise entre environ 41 °C et environ 50 °C à travers les passages d'air pulmonaire (30, 30') remplis du liquide, puis à retirer le milieu liquide (110). Le milieu liquide (110) peut être constitué par un liquide de perfluorocarbone ou par une solution saline physiologique. Les liquides de perfluorocarbone appropriés se caractérisent par un poids moleculaire moyen compris entre environ 350 et environ 560 pour les liquides à échauffement exogène, tels que FC-84, FC-72, RM-82, FC-75, RM-101 et perfluorodécaline, ou par un poids moleculaire moyen compris entre environ 400 et environ 500 pour les liquides chauffés par ultrasons intracorporellement. L'invention se rapporte également à des cathéters d'isolation et d'infusion de liquide (20), à des applicateurs d'ultrasons intracavité (76, 130), ainsi qu'à des applicateurs d'ultrasons intracostaux (66, 68) pour lesdits traitements par convection et/ou par hyperthermie ultrasonore du cancer des poumons.
摘要:
A system for instilling a medium into portions of a luminal network comprising an extended working channel 50 navigable to a treatment target within a patient; and a catheter 115, extendible through the extended working channel and configured to transport medium to the treatment target, the catheter including: a distal and a proximal end; an isolation mechanism including one or more balloons 407 configured to contact walls of the luminal network in order to prevent the medium and air from passing, thereby isolating a portion of the lungs; an inlet at the proximal end configure to receive the medium; and one or more outlets 403 near the distal end configured to dispense the medium to the treatment target.
摘要:
A tracheostomy tube has an inflatable sealing cuff (11) towards its patient end (6) and a fluid-permeable cuff (31) mounted on the shaft (1) above the inflatable cuff. The fluid-permeable cuff (31) contains hydrogel granules (32) that absorb moisture in the trachea (T) and help reduces the amount of secretions leaking past the sealing cuff (11). When the tube is to be withdrawn from the trachea (T) the lower, inflatable cuff (11) is deflated allowing the upper, fluid-permeable cuff (31) to be flattened against the outside of the lower cuff.
摘要:
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.

In an embodiment, a tracheal tube system has a first tube, which is flexible. The tube has an opening that is located on the sidewalls. A balloon is attached to the flexible tube. When inflated, the balloon forms a second tube surrounding the first tube with an air space between the first wall of the balloon and the sidewalls of the first tube. The balloon extends covering the opening on the sidewall. Air flowing into the first tube exits, via the third opening into the airspace between the first tube and the balloon, out of the airspace. In another embodiment, the balloon has a tube with multiplicity of holes in the walls is wrapped around the outer wall of the balloon. Negative pressure in the third tube creates suction holding the outer wall of the balloon to walls of the trachea.
摘要:
The present invention relates to an assembly for controlling a temperature of at least a part of a person, comprising an esophagus catheter to be inserted into the esophagus of the person for controlling the temperature. The esophagus catheter extends along a longitudinal axis and comprises a proximal heat exchanger defining a first flow direction having a first axial component relative to the longitudinal axis, and a distal heat exchanger defining a second flow direction having a second axial component relative to the longitudinal axis. The esophagus catheter further comprises a plurality of coolant channels each in fluid communication with at least one of the proximal heat exchanger and the distal heat exchanger, and a coolant pump connected or connectable to at least one of the plurality of coolant channels. The assembly is configured to cause simultaneously a coolant flow through the proximal heat exchanger and the distal heat exchanger.
摘要:
The present invention is a dual lumen endobronchial tube provided with a flexible wall dividing a cylindrical main tube into two lumens, where the outside wall of the main tube is reinforced, preferably by metal wire but alternately by a sufficiently rigid polymer ribbing which will achieve a desired reduction necessary outside wall thickness. The achievement of a reduction in necessary wall thickness enables sufficient hydraulic cross sectional area so that each lumen is capable independently of providing adequate ventilation to a patient even while a ventilation lumen is partly occluded when the insertion end of a bronchoscope or tube is inserted into the adjacent lumen to examine or treat the other lung.
摘要:
An apparatus for monitoring EMG signals of a patient's laryngeal muscles including an endotracheal tube having an exterior surface. Conductive ink electrodes are formed on the exterior surface of the endotracheal tube. The conductive ink electrodes are configured to receive the EMG signals from the laryngeal muscles when the endotracheal tube is placed in a trachea of the patient. At least on conductor is coupled to the conductive ink electrodes and is configured to carry the EMG signals receive by the conductive ink electrodes to a processing apparatus.
