  • Publication number: 20080033396
    Abstract: A percutaneous luminal access system comprises a thin-walled, collapsible sheath, an introducer, a hemostatic valve, and an access catheter. An introducer may comprise either a pusher tube or an elongate member, or where the introducer is used to axially advance the sheath into a blood vessel or other target lumen. A hemostatic valve may be connected to a proximal end of the sheath, and the access catheter introduced through the hemostatic valve. Pressurized fluid may also be introduced through the hemostatic valve and delivered through a flow region around the catheter within the sheath and optionally through the catheter to the target luminal site.

  • Publication number: 20070265639
    Abstract: Methods for treating a network of organs including generating a map of at least a portion of the network of organs using a rendering system; selecting at least one treatment location within the luminal passageway of the network of organs; and applying an energy therapy to the treatment location to treat the smooth muscle tissue, where the energy therapy applied to the respective treatment location is defined by a plurality of parameters that are associated with a map. Such a system allows for historical or ideal treatment parameters to be identified, visually or otherwise to actual treatment locations. Also, control systems and methods for delivery of energy that may include control algorithms that prevent energy delivery if a fault is detected and may provide energy delivery to produce a substantially constant temperature at a delivery site. In some embodiments, the control systems and methods may be used to control the delivery of energy, such as radio frequency energy, to body tissue, such as lung tissue.

  • Publication number: 20070118184
    Abstract: This relates to methods and devices for treating reversible chronic obstructive pulmonary disease, and more particularly, relates to a device for exchanging energy with airway tissue such as that found in the airway of human lungs. The exchange of energy with this airway tissue in the airways reduces the ability of the air ways to constrict and/or reduces the resistance within the airway to the flow of air through the airway. This also relates to a method for decreasing responsiveness or decreasing resistance to airflow of airways involves the transfer of energy to or from the airway walls to prevent or reduce airway constriction and other symptoms of lung diseases. The treatment reduces the ability of the airway to contract during an acute narrowing of the airways, reduces mucus plugging of the airways, and/or increases the airway diameter.

  • Publication number: 20070083197
    Abstract: A method for treating the lung during an acute episode of reversible chronic obstructive pulmonary disease such as an asthma attack. The method comprises transferring energy to an airway wall of an airway such that a diameter of the airway is increased. The energy may be transferred to the airway wall prior to, during or after an asthma attack. The energy may be transferred in an amount sufficient to temporarily or permanently increase the diameter of the airway. The method may be performed while the airway is open, closed or partially closed.

  • Publication number: 20060260617
    Abstract: A tracheostomy is performed using an access device and a separate ventilation device. The access device is introduced through a surgical opening in the tracheal wall and has an anchor which is expanded in situ to hold the access device in place. The ventilation device is introduced through a passage in the access device and has an expandable cuff which is oriented above the access point through the tracheal wall. A concavity in the expandable cuff collects body secretions, and other materials from the oral and nasal cavities and/or gastro-intestinal reflux into the trachea, and the collected secretions are removed by aspiration through a lumen provided in the ventilation device. A one-way valve may be provided in the expandable cuff in order to permit exhalation through the larynx to assist in speech.

  • Publication number: 20060247727
    Abstract: The present invention includes a system for delivering energy to an airway wall of a lung comprising an energy delivering apparatus and a PID controller having one or more variable gain factors which are rest after energy deliver has begun. The energy delivering apparatus may include a flexible elongated member and a distal expandable basket having at least one electrode for transferring energy to the airway wall and at least one temperature sensor for measuring temperature. The PID controller determines a new power set point base on an error between a preset temperature and the measured temperature. The algorithm can be Pi+1=Pi+G(?ei+?ei?1+?ei?2) where ?, ? and ? are preset values and ? is from 1 to 2; ? is from ?1 to ?2; and ? is from ?0.5 to 0-5. In another variation, the controller is configured to shut down if various measured parameters are exceeded such as, for example, energy, impedance, temperature, temperature differences, activation time and combinations thereof.
