    Abstract: There are provided devices for applying negative pressure to a wound in an endoluminal surface of a patient to facilitate healing of the wound and methods for use of the devices. The device (69, 94, 134, 140, 156, 164) comprises a flexible porous element with an outer face defined between opposite proximal and distal ends of the porous element. A suction tube (30) for being connected to a suction source externally of the patient's body is in fluid communication with the porous element (14) to apply the negative pressure to the wound via the outer face of the porous element. In some embodiments, the porous element has a longtitudinal passageway (16) for passage of bodily substances of the patient along the lumen defining the endoluminal surface through the porous element. In such embodiments, the device may also have at least one absorbent element (70, 80) for absorbing the bodily substances and which is disposed forwardly or rearwardly of the porous element (14).

  • Patent number: 10307517
    Abstract: Negative pressure wound therapy apparatuses and dressings, and systems and methods for operating such apparatuses for use with dressings are disclosed. In some embodiments, controlling the delivery of therapy can be based on monitoring and detecting various operating conditions. An apparatus can have a controller configured to monitor the duty cycle of a source of negative pressure and, based on the monitored duty cycle, determine whether a leak is present. The controller can be configured to provide an indication that a leak is present. For example, the controller can be configured to suspend and/or pause the delivery of therapy, and to restart the delivery of therapy due to a timeout, request from a user, etc. In addition, the controller can be configured to pause and/or restart the delivery of therapy upon a request from the user, such as in response to the user operating a switch.

  • Patent number: 10182947
    Abstract: Disclosed herein is a device which is intended to deliver and maintain reduced pressure to body surfaces for application of reduced pressure wound therapy (RPWT) also known as negative pressure wound therapy (NPWT). During application of this type of therapy, a substantially airtight seal is formed around a section of tissue to be treated. This seal is formed by a dressing which provides fluid communication from a section of tissue to a reduced pressure source. Disclosed herein is a dressing system which is configured to enhance usability and functionality of this dressing. First, the system may be configured to allow full rotation of the fluid communication conduit to the reduced pressure source along the axis substantially normal to the dressing. Second, the system may be configured to include a one-way valve to prevent backflow of any drainage fluids. Third, the system may be configured with transparent windows covered by opaque flaps to allow inspection through the dressing.

  • Patent number: 10149783
    Abstract: This invention provides an oral apparatus and method capable of alleviating or curing snore and obstructive sleep apnea by applying a negative pressure through a mini oral interface to the oral cavity. The mini oral interface creates a secure connection between the interface and mouth or teeth and prevents the interface from falling off. The oral interface also provides fixation between upper and lower lips (or tooth) and prevents opening of patient's mouth during sleeping. The negative pressure pulls the tongue toward upper palate and also pulls the soft palate forward as well. By moving the tongue and the soft palate in a forward direction, the patentcy of the upper airway near the pharynx is maintained to prevent sleep-disordered breathing. The negative pressure will pull the lips inward to close the mouth ad prevent air from entering the oral cavity from atmosphere.

Apparatus is configured to direct first and second air flows such that the plume is not deposited on the material being cut by the laser or on the focusing optic.

  • Patent number: 9050399
    Abstract: Apparatus (130) for use in wound therapy of mammals is described, the apparatus (130) comprising: a dressing covering the wound, the dressing being substantially sealed to prevent ingress of ambient atmospheric air to the wound; aspiration means (132) operably connected to a space between the dressing and the wound by an aspiration conduit (142) sealed to the point of entry between wound and dressing against ingress of ambient atmosphere, said conduit (142) being for aspiration of said wound and for removal of fluid from said space between said wound and said dressing; a waste container (148) for receiving aspirated fluid to be discarded operably connected to said aspiration conduit; and heating means (144) for heating said fluid in order to increase the vapor pressure thereof and to cause evaporation to reduce the volume of the fluid in the waste container (148). In a preferred embodiment of the present invention the waste fluid is also provided with a sparge gas.

  • Patent number: 9033942
    Abstract: A wound dressing for use in a vacuum wound therapy treatment includes a backing layer for positioning over a wound to define a reservoir in which a reduced pressure may be maintained over the wound. A portal member affixed to the backing layer provides a connection to a reduced pressure source through an opening in an ambient surface. A primary port extends between the opening and a primary aperture in a reservoir surface to providing fluid communication between the reservoir and the reduced pressure source. At least one supplemental port establishes fluid communication between the primary port and a supplemental aperture in the reservoir surface that is distinct and substantially spaced from the primary aperture.

  • Patent number: 9011393
    Abstract: Methods, devices, and systems are disclosed that help to restore lymphatic flow associated with a subcutaneous defect in a patient's body by approximating portions of the subcutaneous defect using reduced pressure and a tissue-approximating device. The tissue approximating device may include a curved member that is formed from a semi-rigid material and defines a concave space that goes over the subcutaneous defect. A flange portion is formed on the curved member. A reduced-pressure aperture is formed on the curved member for providing reduced pressure to the concave space. The tissue-approximating device also includes a spacer member disposed on a tissue-facing side of the curved member and aligned substantially with the reduced-pressure aperture. Other systems, devices, and methods are disclosed.

  • Patent number: 9012714
    Abstract: A wound treatment device comprises a wound surface contacting plug and a cover for covering the wound surface and the plug, wherein said plug consists of a flat textile isolating material comprising at least one first surface layer, one second surface layer and one intermediate space arranged between said surface layers. At least the first surface layer is provided with a biocompatible surface and a structure which enables a liquid to pass and prevents a wound tissue from growing in said structure. The intermediate space is provided with isolating threads elastically holding the first surface layer and the second surface layer at a certain distance from each other.
