Patent number: 11951241Abstract: Described herein are systems and methods for performing peritoneal dialysis. According to one aspect, the disclosure provides a sterile interface connection for connecting a water purification system to a disposable source of dialysate concentrates. The sterile interface connection can include a chamber comprising an inlet adapted to be connected to the water purification system on a proximal end and a valve on a distal end. The sterile interface connection can also include spring-loaded needle disposed in the chamber. The spring-loaded needle can move between a retracted configuration in which the spring-loaded needle is fully retracted into the chamber and the valve is closed and sealed, and an extended configuration in which the spring-loaded needle extends through the valve into the disposable source of dialysate concentrates.Type: GrantFiled: November 28, 2022Date of Patent: April 9, 2024Assignee: Outset Medical, Inc.Inventors: James Ritson, Michael Edward Hogard, Gopi K.

Patent number: 11446184Abstract: 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: GrantFiled: November 30, 2018Date of Patent: September 20, 2022Assignee: KCI Licensing, Inc.Inventors: Dean Hu, Kenton Fong, Moshe Pinto, Philip Hui, Kenneth Wu, Craig McGreevy, Evan Anderson

Patent number: 11027050Abstract: 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.Type: GrantFiled: August 16, 2016Date of Patent: June 8, 2021Assignee: KCI Licensing, Inc.Inventors: Dean Hu, Kenneth Wu

Patent number: 10792404Abstract: 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 20, 2016Date of Patent: October 6, 2020Assignee: KCI Licensing, Inc.Inventors: Dean Hu, Kenton Fong, Moshe Pinto, Kenneth Wu, Craig McGreevy, Brendan Donohoe
