  • Patent number: 8206684
    Abstract: Disclosed is a method of regulating fluid flow for a targeted lung region. The method comprises injecting a therapeutic agent into the targeted lung region. The therapeutic agent induces a reaction in lung tissue of the targeted lung region or in a collateral pathway to the lung region to reduce collateral fluid flow into the targeted lung region. In one aspect, the method additionally comprises deploying a bronchial isolation device in the direct pathway to regulate fluid flow to the targeted lung region through the direct pathway. The therapeutic agent can comprise, for example, a sclerosing agent that induces a reaction that causes sclerosis in the lung tissue.

  • Publication number: 20110226238
    Abstract: Disclosed are methods and devices for regulating fluid flow to and from a region of a patient's lung, such as to achieve a desired fluid flow dynamic to a lung region during respiration and/or to induce collapse in one or more lung regions. Pursuant to an exemplary procedure, an identified region of the lung is targeted for treatment. The targeted lung region is then bronchially isolated to regulate airflow into and/or out of the targeted lung region through one or more bronchial passageways that feed air to the targeted lung region.

  • Publication number: 20110220104
    Abstract: A method and system for increasing the flow resistance of collateral pathways in the lung by employing aspiration to establish an artificial convective flow current between compartments in the lung in order to entrain and deliver a clogging agent preferentially to the collateral pathways. The method may sometimes be performed after lung has been assessed for the presence of collateral pathways.

  • Publication number: 20110130834
    Abstract: Methods and systems for lung volume reduction of a patient are described. The methods include implanting a flow control device in a bronchial passageway of the lung. The flow control device regulates fluid flow through the bronchial passageway and includes a valve protector that at least partially surrounds a valve member. The valve protector has sufficient rigidity to maintain the shape of the valve member against compression.

  • Publication number: 20110017207
    Abstract: Disclosed is a flow control device for a bronchial passageway. The device can includes a valve member that regulates fluid flow through the flow control device, a frame coupled to the valve member, and a membrane attached to the frame. At least a portion of the flow control device forms a seal with the interior wall of the bronchial passageway when the flow control device is implanted in the bronchial passageway. The membrane forms a fluid pathway from the seal into the valve member to direct fluid flowing through the bronchial passageway into the valve member.

  • Patent number: 7717115
    Abstract: Disclosed is an apparatus for deploying a bronchial isolation device in a bronchial passageway in a lung of a patient. In one embodiment, the apparatus includes an outer shaft having a distal end. A housing is coupled to the distal end of the outer shaft and configured to receive the bronchial device. An inner shaft is slidably disposed within the outer shaft. A handle is adapted to move the outer shaft relative to both the inner shaft and the handle while the inner shaft remains fixed relative to the handle so as to eject the bronchial isolation device from the housing.

  • Publication number: 20090255537
    Abstract: Disclosed are various disease indications and treatment methods that benefit from selective lung region isolation. A lung region is bronchially isolated by regulating the flow of fluid to and from the lung region, such as by implanting one or more bronchial isolation devices into one or more bronchial passageways that feed air to the lung region. The bronchial isolation devices can comprise, for example, one-way valves, two-way valves, occluders or blockers, ligating clips, glues, sealants, and sclerosing agents.

  • Publication number: 20080249503
    Abstract: A method of treating a lung comprises deploying a delivery catheter through a bronchial tree into a targeted lung region and delivering a fibrinogen suspension through the delivery catheter so that the fibrinogen suspension exits the distal end of the delivery catheter into the targeted lung region. Thrombin is also delivered through the delivery catheter so that the thrombin exits the distal end of the delivery catheter into the targeted lung region. The lung is promoted to collapse.

  • Patent number: 7412977
    Abstract: Disclosed are methods and devices for regulating fluid flow in one or more lung regions that are supplied fluid through one or more collateral pathways. An identified region of the lung is targeted for volume reduction or collapse. The targeted lung region is then bronchially isolated to inhibit air from flowing into the targeted lung region through bronchial pathways that directly feed air to the targeted lung region. If the targeted lung region does not collapse after bronchially isolating the targeted lung region, then it is possible that a collateral pathway is feeding air to the targeted lung region, thereby preventing the targeted lung region from collapsing. In such a case, the collateral pathway is identified and air flow into the targeted lung region via the collateral pathway is reduced or eliminated.

  • Patent number: 6941950
    Abstract: Disclosed are methods and devices for regulating fluid flow to and from a region of a patient's lung, such as to achieve a desired fluid flow dynamic to a lung region during respiration and/or to induce collapse in one or more lung regions. An identified region of the lung is targeted for treatment, such as to modify the flow to the targeted lung region or to achieve volume reduction or collapse of the targeted lung region. The targeted lung region is then bronchially isolated to regulate airflow into and/or out of the targeted lung region through one or more bronchial passageways that feed air to the targeted lung region. The bronchial isolation of the targeted lung region is accomplished by implanting a flow control device into a bronchial passageway that feeds air to a targeted lung region.
