  • Patent number: 8518053
    Abstract: Surgical instruments and techniques are provided for creating a pneumostoma through the chest wall into the lung of a patient. The pneumostomy instruments and techniques may be used to create a pneumostoma which allows gases to escape from the lung through the chest wall and thereby treat chronic obstructive pulmonary disease.

  • Patent number: 8506577
    Abstract: A two-phase surgical procedure is disclosed for creating a pneumostoma to treat chronic obstructive pulmonary disease The first phase is a procedure to induce creation of a localized pleurodesis and is preferably performed as an outpatient procedure. The second phase is a procedure to introduce a surgical instrument into the lung via the pleurodesis to create the pneumostoma. An interval of about one of more days between the first and second phases allows the formation of a stable pleurodesis to prevent pneumothorax during the procedure.

  • Patent number: 8491602
    Abstract: A single-phase surgical procedure is disclosed for creating a pneumostoma to treat chronic obstructive pulmonary disease. In a single-phase technique the pleurodesis is formed at the same time as the pneumostoma and does not require a separate step. The thoracic cavity is accessed to visualize the lung, the pneumostomy catheter is inserted into the lung and then the lung is secured to the channel through the chest wall creating a sealed anastomosis which matures into a pleurodesis after the procedure.

  • Patent number: 8474449
    Abstract: A flexible pneumostoma management device maintains the patency of a pneumostoma while controlling the flow of material through the pneumostoma. The pneumostoma management device includes flange attaches to the chest of the patient to secure the device in position. The pneumostoma management device also includes a tube which enters the pneumostoma to allow gases to escape the lung. The length of the tube is selected to match the dimensions of the pneumostoma of a patient. In order to manufacture devices having different tube lengths, the tube is formed at a longer length than required, cut to size and tipped. The tube may be formed by molding or extrusion.

  • Patent number: 8475389
    Abstract: A pneumostoma assessment and treatment system includes methods and devices for aftercare of a pneumostoma. In particular, methods and devices are provided for standardized monitoring and assessment of pneumostoma patency thereby facilitating the establishment of standards-based protocols for pneumostoma management. Methods of standardized pneumostoma patency assessment includes the use of devices for raising alveolar pressure to a controlled repeatable pressure above ambient while analyzing gas flow through the pneumostoma. In response to an assessment the functionality of the pneumostoma, the tissues of the pneumostoma may be treated with a treatment device utilizing one or more different modalities to preserve or enhance the health and function of the pneumostoma.
