Means Placed In Body Opening To Facilitate Insertion Of Breathing Tube Patents (Class 128/200.26)
  • Publication number: 20130025588
    Abstract: A loading dilator for positioning a medical apparatus across an opening formed through a body wall of a patient includes a tubular body having a relatively rigid proximal portion and a distal portion. The distal portion includes a first relatively flexible segment and a second relatively rigid segment. The first segment is axially extendable from a first length that has a greater diameter than the second segment, to a second length having a diameter that does not substantially exceed the diameter of the second segment. A stylet is movable in a passageway of the tubular body between a first position wherein the first segment has the first length, and a second position wherein the stylet distal end exerts an axially displacing force on the second segment such that the first segment is movable from the first length to the second length.

  • Publication number: 20130019864
    Abstract: Methods, systems and devices are described for new modes of ventilation in which specific lung areas are ventilated with an indwelling trans-tracheobronchial catheter for the purpose of improving ventilation and reducing hyperinflation in that specific lung area, and for redirecting inspired air to other healthier lung areas. Trans-tracheobronchial Segmental Ventilation (TTSV) is performed on either a naturally breathing or a mechanical ventilated, patient by placing a uniquely configured indwelling catheter into a bronchus of a poorly ventilated specific lung area and providing direct ventilation to that area. Typically the catheter's distal tip is anchored without occluding the bronchus. TTSV is optionally performed by insufflation only of the area, or by the application of vacuum to the area, can include elevating or reducing the pressure in the targeted area to facilitate stagnant gas removal, or can include blocking the area to divert inspired gas to better functioning areas.

  • Patent number: 8342182
    Abstract: Lung conditions are diagnosed and optionally treated using a functional assessment catheter or a functional lung assessment and treatment catheter. A flow restrictive component is initially placed in a bronchus or lung passageway upstream from a diseased lung region. The isolated lung region is then functionally assessed through the catheter, while the flow restrictive component remains in place. If the patient is a good candidate for treatment by occlusive or restrictive treatment techniques, the flow resistive component may be left in place. If the patient is not suitable for such treatment, the flow resistive component may be removed.

  • Publication number: 20120279499
    Abstract: This device is designed to be an alternative to the traditional conscious intubation with a cooperative patient. It harnesses the negative pressure created during inhalation and utilizes it to advance a guidewire into the trachea, which then allows for endotracheal intubation. The negative pressure created during a deep inhalation will force air through a hollow delivery tube and carry a Sail-tipped wire through the vocal cords and into the trachea. Once the wire has been deployed, a syringe is attached and air is inflated into the expandible polymer sail. This will expand the sail into a balloon shape, create traction against the walls of the trachea and secure the guide-wire. An endotracheal tube may then be advanced blindly, using the wire as a guide to correct tracheal position and the NPI device removed.

  • Patent number: 8220454
    Abstract: An airway device (10) comprising an airway tube (14) and a laryngeal mask (12). The mask has an inflatable cuff (36) which has a tip (38) for insertion, in use, into a patient's oesophagus. The mask further includes a guide member (42) projecting from the tip of the cuff. The guide member carries an inflatable balloon (60) for blocking the patient's oesophagus during use. The guide member helps to position the mask correctly and reduces the risk of pulmonary aspiration of gastric contents during use.

  • Patent number: 8220461
    Abstract: An oral airway for insertion into the mouth and pharynx of a patient is disclosed and adapted to connect to an anesthesia breathing connector, a suction tube, or a nasal cannula, interchangeably as needed, without necessitating the removal of the oral airway from the patient. A tubular member has a connector at a proximal end and includes a first portion that is adapted for fixing with the anesthesia breathing connector. A second portion of the connector is adapted for receiving the suction tube. At least one protuberance between the first and second portions receives and retains a portion of the nasal cannula, or alternately, at least one aperture is included in the second portion for receiving a portion of the nasal cannula. A mouth guard extends outwardly from the connector. Alternately, a suction tube guide within the tubular member may be slidably positionable between a retracted and extended position.

    Abstract: A bougie device for guiding insertion of an endotracheal tube into an airway of a person, comprises an elongate body of shape memory and self-lubricating material, for example Teflon™. Accordingly no lubrication is required for insertion into the airway for ease of cleaning and sterilizing for reuse. Also, the amount of curvature of the overall rod as well as an angle of the tip of the rod can be adjusted due to the shape memory characteristics of the body to accommodate a particular patent's airway. The body can also be suitably sized to have vibration transmission characteristics such that a contact with one end of the bougie device with tracheal rings of the patient can be felt by a user.
