Patent number: 8409159Abstract: 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 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.Type: GrantFiled: April 9, 2010Date of Patent: April 2, 2013Assignee: Spiracur, Inc.Inventors: Dean Hu, Kenton Fong, Moshe Pinto, Kenneth Wu, Craig McGreevy, Brendan Donohoe

Patent number: 8398604Abstract: Disclosed are devices, systems and methods for treating an incision. The device includes a generally planar tension relief module, comprising a central structure in fluid communication with the incision, wherein at least a portion of the central structure is adapted to be aligned with a longitudinal axis of the incision; and opposing adhesive structures coupled to the central structure and a flexible sealant structure comprising a lower adhesive surface and sized to seal over the tension relief module forming a sealed flow pathway. The opposing adhesive structures are adapted to be stretched from a relaxed configuration to a first tensile configuration and to return towards the relaxed configuration from the first tensile configuration into a second tensile configuration and impart a contracting force in a direction that is towards the opposing adhesive structure.Type: GrantFiled: September 26, 2011Date of Patent: March 19, 2013Assignee: Spiracur, Inc.Inventors: Kenneth Wu, Dean Hu, Sumona Nag

Publication number: 20100137775Abstract: 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.Type: ApplicationFiled: November 25, 2009Publication date: June 3, 2010Applicant: Spiracur Inc.Inventors: Dean HU, Kenton Fong, Moshe Pinto, Philip Hui, Kenneth Wu, Craig McGreevy, Evan Anderson
