  • Patent number: 8002740
    Abstract: Devices and methods for altering gaseous flow within a lung to improve the expiration cycle of an individual, particularly individuals having chronic obstructive pulmonary disease. The methods and devices create channels in lung tissue and maintain the patency of these surgically created channels in tissue. Maintaining the patency of the channels allows air to pass directly out of the lung tissue which facilitates the exchange of oxygen ultimately into the blood and/or decompresses hyper-inflated lungs.

  • Publication number: 20100312141
    Abstract: Methods, devices, and systems are described herein that allow for improved sampling of tissue from remote sites in the body. A tissue sampling device comprises a handle allowing single hand operation. In one variation the tissue sampling device includes a blood vessel scanning means and tissue coring means to excise a histology sample from a target site free of blood vessels. The sampling device also includes an adjustable stop to control the depth of a needle penetration. The sampling device may be used through a working channel of a bronchoscope.

  • Publication number: 20090318904
    Abstract: The devices and methods of placement of such devices disclosed herein are directed to altering gaseous flow within a lung to improve the expiration cycle of, for instance, an individual having Chronic Obstructive Pulmonary Disease. More particularly, these devices produce and maintain collateral openings or channels through the airway wall so that oxygen depleted/carbon dioxide rich air is able to pass directly out of the lung tissue to facilitate both the exchange of oxygen ultimately into the blood and/or to decompress hyper-inflated lungs. The medical kits disclosed herein are also directed to produce and maintain collateral openings through airway walls.

  • Publication number: 20090287087
    Abstract: Devices and methods are disclosed for creating passages in tissue and detecting blood vessels in and around the passages. The devices may be used to create opening in tissue without removing a sensing assembly from the tissue. The devices herein may be used for altering gaseous flow within a lung to improve the expiration cycle of an individual, particularly individuals having Chronic Obstructive Pulmonary Disease (COPD). In addition, the devices may be used to sample tissue during biopsy or other medical procedures where perforating a blood vessel could result in injury to a patient.

  • Publication number: 20090204005
    Abstract: Devices and methods are disclosed for providing a sensing element to scan tissue and detect the presence of structures within the tissue to avoid the structures when performing a procedure on the tissue. A tissue penetrating member or needle is extendable from the device to create a channel or opening through the wall of an airway. The device is sufficiently flexible to navigate turns of at least 90 degrees. The distal section of the device includes puncture resistant sections, a curved needle tip, and depth limiting features that serve to create a channel in the lumen wall without causing collateral damage to the instruments, or patient.

  • Publication number: 20090131765
    Abstract: Minimally invasive systems and methods are described for measuring pulmonary circulation information from the pulmonary arteries. A transbronchial Doppler ultrasound catheter is advanced through the airways and in the vicinity of the pulmonary artery. Doppler ultrasound energy is sent through the airway wall and across the pulmonary artery to obtain velocity information of blood flowing through the artery. The velocity information is used to compute pulmonary circulation information including but not limited to flowrate.

    Abstract: The methods disclosed herein are directed to altering gaseous flow within a lung to improve the expiration cycle of, for instance, an individual having Chronic Obstructive Pulmonary Disease. More particularly, these methods produce and maintain collateral openings or channels through the airway wall so that expired air is able to pass directly out of the lung tissue to facilitate both the exchange of oxygen ultimately into the blood and/or to decompress hyper-inflated lungs. Devices and methods apply cryo-energy to maintain the patency of the surgically created openings.

  • Patent number: 7422584
    Abstract: This is directed to improving the gaseous exchange in a lung of an individual and particularly, this is directed to improving the gaseous exchange in individuals having chronic obstructive pulmonary disease. It generally includes fluidly connecting the lung to an extrapleural airway such as the trachea. In one variation, a conduit is deployed to place the lung and the trachea in fluid communication which allows trapped oxygen-reduced air to pass directly out of the lung and into the trachea. Removing nonfunctional air from the lung tends to improve the gaseous exchange of oxygen into the blood and decompress hyper-inflated lungs. Sealant and biocompatible adhesives may be provided on the exterior of the conduit to prevent side flow, leaks and to otherwise prevent air from entering spaces not intended to receive air such as the pleura space.
