Abstract: A surgical tissue therapy device includes a sealant layer and a collection chamber. The sealant layer functions so as to create a sealed enclosure or space between it and the surface of a patient by forming, preferably, an airtight seal around a surgical area of skin trauma. The closed incision tissue therapy device also comprises a collection chamber, which may comprise an elongate tubular chamber with a plurality of longitudinally spaced openings. The collection chamber may be configured to be in fluid communication with the sealant layer and the area of skin trauma and functions as to distribute the negative pressure applied to a surgically closed area of skin trauma. Preferably, the pressure under the sealant layer is reduced by expanding the volume of the enclosure space and thereby decreasing the density of air molecules under the sealant layer. The collection material may comprise a material and/or a configuration that permits length changes based upon the length of the corresponding surgical wound or incision.

Abstract: Disclosed herein are devices, systems and methods for delivering reduced pressure to a load-bearing wound site. The device can include a distal port configured to connect to a wound dressing positioned over the wound site; a proximal port located a distance from the distal port and configured to connect to a reduced pressure source, and a conduit body having an inner channel extending between the distal port and the proximal port. When the distal port is applied to the wound dressing positioned over the wound site the proximal port is positioned at a non-load bearing location remote from the wound dressing. The inner channel has a non-circular profile having a width larger than a height of the conduit body.

Abstract: Reduced pressure wound therapy is performed on a sacral region of a patient using an adhesive dressing comprising a flexible planar layer and a non-planar fold-sealing region configured to seal to the intergluteal cleft of a patient. The fold-sealing region is located on an outer edge of the adhesive dressing and comprises a tapered configuration.

Abstract: Disclosed herein are devices, systems and methods for using such devices and systems for treating incisions and wounds. In an aspect, disclosed is a device having a generally planar tension relief module and a flexible sealant structure sized to cover the tension relief module, the flexible sealant structure comprising a lower adhesive surface. The tension relief module includes a conduit structure having a plurality of support structures on an upper surface of the conduit structure and at least one opening extending through the conduit structure from a lower surface to the upper surface. At least a portion of the conduit structure is adapted to be aligned with a longitudinal axis of the incision. The tension relief module also includes opposing adhesive structures coupled to the conduit structure. The lower adhesive surface of the flexible sealant structure and the upper surface of the conduit structure form a flow pathway.

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. Fourth, the system may be configured to include an indicator which visually makes clear whether reduced pressure is being applied or not. Fifth, the system is configured to minimize the profile of the dressing system.

Abstract: Disclosed herein are devices and methods for reduced pressure tissue therapy. Some variations of suction devices for reduced pressure tissue therapy comprise a housing, a suction force generating mechanism located within the housing, and a storage module configured to retain tissue exudates. In some variations, the storage module includes a sleeve configured to collect tissue exudates. The sleeve may include a support element to help maintain the lateral structural integrity of the sleeve and/or retain the cross-sectional geometry of the sleeve under negative pressure. In use, the storage module may reduce sanitary and/or biohazard risks by preventing the exudates from contacting the housing and/or suction force generating mechanism. The storage module is configured to be replaced so that the housing and suction force generating mechanism can be used for more than one session.
