  • Publication number: 20100170507
    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 a pneumostoma vent having a tube which enters the pneumostoma to allow gases to escape the lung, a flange and a filter/valve to control flow of materials through the tube. The flange is a thin flexible patch comprises of multiple thin layers of materials and which conforms and attaches to the chest of the patient. The flange includes a filter, a protective outer layer and an inner hydrocolloid layer. The flange secures the tube in position in the pneumostoma. An indicator responsive to gases exiting the pneumostoma is integrated into the device and provides and external indicia of the patency and efficacy of the pneumostoma.

  • Patent number: 7682332
    Abstract: Methods for creating an anastomosis between a channel through the chest wall and an opening in the visceral membrane of a lung using a medical device. The methods include creating the channel through the chest wall into the pleural cavity; forming an adhesion between the chest wall and the visceral membrane of the lung; creating an opening in the visceral membrane of the lung which communicates with the channel; and inserting the medical device into the channel. The medical device has a compression structure which spans the channel. The methods include configuring the compression structure to apply a compressive force to tissue surrounding the anastomosis and/or applying agents and materials to the tissue of the anastomosis thereby accelerating the formation and healing of the anastomosis.

  • 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.

  • Patent number: 7608086
    Abstract: An anastomotic ring device for forming a hollow rivet (ring) attachment between tissue lumens facilitates laparoscopic or endoscopic implantation by including features that facilitate actuation from a stressed, generally cylindrical shape. Economical manufacturer is achieved by weaving open ended strands into a generally cylindrical stent shape that is imparted with a Shape Memory Effect (SME) to actuate to a hollow rivet (ring) shape. Alternatively or in addition to SME inherent in the woven strands, an actuating force may be received from a helical spring element incorporated into the ring. Self-actuating ring devices are enhanced by forming woven strands into petals that diverge from opposing petals such that the strands encounter less friction when actuating. Each of these features alone or in combination enhance clinical use of anastomotic ring devices, such as a bariatric gastric bypass procedure.

  • Publication number: 20090205665
    Abstract: A pneumostoma assessment and treatment system includes methods and devices for aftercare of a pneumostoma and for additional patient care utilizing a pneumostoma. The system utilizes a number of modalities to assess the health and functionality of the pneumostoma, the lungs and/or the patient as a whole. In response to an assessment of the health and functionality of the pneumostoma, lungs and patient, the tissues of pneumostoma may be treated with a treatment device and utilizing one or more different modalities to preserve or enhance the health and function of the pneumostoma and/or treat other conditions of the patient.

  • Publication number: 20090209924
    Abstract: A partially-implantable pneumostoma management device maintains the patency of a pneumostoma while controlling the flow of material through the pneumostoma. A tube of the pneumostoma management device is placed through the chest wall into the lung. The tube comprises a plurality of holes in the distal end to allow the entry of gases and non-gaseous discharge from the lung. A contact surface prevents over-insertion of the tube while releasably securing the device to the chest of the patient. The contact surface has features to reduce irritation of the skin of the chest.

  • Publication number: 20090205645
    Abstract: A method for maintaining the patency of a pneumostoma while controlling the flow of material through the pneumostoma. A pneumostoma management system includes a two-part pneumostoma management device and associated insertion and removal tools. The pneumostoma management device includes a pneumostoma vent and a chest mount for positioning and securing the vent into a pneumostoma. To use the system, the chest is first cleaned and the chest mount secured to the chest adjacent the pneumostoma. The pneumostoma vent is then inserted into the pneumostoma through an aperture in the chest mount until it is engaged and secured by a coupling of the chest mount. The pneumostoma vent may be replaced periodically such as daily. The chest mount may be changed less frequently such as weekly.
