20090299255 | REDUCED-PRESSURE DRESSING ASSEMBLIES FOR USE IN APPLYING A CLOSING FORCE - A closing dressing bolster and assembly for use with a system for treating a linear wound on a patient includes a bolster body formed from a flexible closing bolster material having closing members that are operable to develop an inward closing force when the closing dressing bolster is placed under reduced pressure. In one aspect, when the closing dressing bolster is under reduced pressure, the system, dressing, or assembly develops an inward force realized at the linear wound and a compression force. A wicking-material holder and wicking material may be used as well. The member components may all be see-through to allow visual inspection of the wound without requiring removal of the dressing. | 12-03-2009 |
20090299256 | SEE-THROUGH, REDUCED-PRESSURE DRESSINGS AND SYSTEMS - A see-through dressing assembly is presented for use with a reduced-pressure system for treating a wound on a patient using reduced pressure that allows visual observation of the wound during treatment. The dressing assembly includes a bolster for providing a directed force when under reduced pressure, a sealing member for covering the bolster and providing a seal over the bolster and a patient's epidermis, and wherein the bolster and sealing member are formed from see-through materials sufficient to allow perception of color from a point external to the system. Other systems, dressings, and methods are presented. | 12-03-2009 |
20090299307 | REDUCED-PRESSURE, LINEAR-WOUND TREATMENT SYSTEMS - A system for treating a linear wound on a patient has a closing dressing bolster for placing on the patient's epidermis over the linear wound, a sealing subsystem for providing a seal over the closing dressing bolster and the patient, and a reduced-pressure subsystem for delivering reduced pressure to the sealing subsystem. The sealing subsystem and reduced pressure subsystem are operable to deliver reduced pressure to the closing dressing bolster. The closing dressing bolster is operable under reduced pressure to develop a inward closing. The closing dressing bolster may include one or more closing members on each side of a center wound area to create the inward closing when under reduced pressure. A compressive force may also be developed. Other systems and methods are presented. | 12-03-2009 |
20110178479 | LEAK-RESISTANT BANDAGE SYSTEMS AND METHODS WITH HYDROPHILIC FOAM WOUND INSERT FOR FLUID-INSTILLATION AND/OR NEGATIVE-PRESSURE WOUND THERAPIES - Wound treatment systems and methods (e.g., having hydrophilic wound inserts), such as for negative-pressure and/or fluid-installation wound therapies. Some embodiments include a check-valve assembly between a wound dressing and a vacuum source. | 07-21-2011 |
20110190703 | SYSTEMS AND METHODS FOR POSITIONING FLUID SUPPLY SYSTEM - Fluid supply systems and methods for therapeutic fluid delivery systems, including those used for negative pressure wound therapy (NPWT) systems and methods. | 08-04-2011 |
20120165765 | REDUCED-PRESSURE, LINEAR-WOUND TREATMENT SYSTEMS - A system for treating a linear wound on a patient has a closing dressing bolster for placing on the patient's epidermis over the linear wound, a sealing subsystem for providing a seal over the closing dressing bolster and the patient, and a reduced-pressure subsystem for delivering reduced pressure to the sealing subsystem. The sealing subsystem and reduced pressure subsystem are operable to deliver reduced pressure to the closing dressing bolster. The closing dressing bolster is operable under reduced pressure to develop a inward closing. The closing dressing bolster may include one or more closing members on each side of a center wound area to create the inward closing when under reduced pressure. A compressive force may also be developed. Other systems and methods are presented. | 06-28-2012 |
20120203189 | SEE-THROUGH REDUCED-PRESSURE DRESSINGS AND SYSTEM - A see-through dressing assembly is presented for use with a reduced-pressure system for treating a wound on a patient using reduced pressure that allows visual observation of the wound during treatment. The dressing assembly includes a bolster for providing a directed force when under reduced pressure, a sealing member for covering the bolster and providing a seal over the bolster and a patient's epidermis, and wherein the bolster and sealing member are formed from see-through materials sufficient to allow perception of color from a point external to the system. Other systems, dressings, and methods are presented. | 08-09-2012 |
20130096536 | SYSTEM AND APPARATUS FOR TREATING A TISSUE SITE HAVING AN IN-LINE CANISTER - A canister for use in administering reduced pressure to a tissue site includes a center body, a first end cap, and a second end cap. The center body includes a first end, second end, and a number of fluidly separate body conduits. The first end cap is connected to the first end of the center body and includes a number of return conduits fluidly connecting one body conduit to another. The first end has a port for receiving a conduit in fluid communication with the tissue site. The second end cap is connected to the second end of the center body and includes a number of return conduits fluidly connecting one body conduit to another. The second end cap has a port for receiving a conduit in fluid communication with a reduced pressure source. The fluid connection between the body conduits and the return conduits creates a continuous, tortuous pathway. | 04-18-2013 |

20140121616 | MEDICAL CANISTER CONNECTORS - A medical canister connector is presented for connecting to a medical canister, which has a patient port and a reduced-pressure port. The medical canister connector includes a first connection member that is coupled to a patient-port-attachment member, which is for coupling to a patient port on a medical canister and has a patient-port opening with a first longitudinal axis. The medical canister connector also includes a second connection member coupled to a reduced-pressure -port-attachment member, which is for coupling to a reduced-pressure port on the medical canister and has a reduced-pressure-port opening with a second longitudinal axis. A spacing member or pressure transport member may be used to couple the first connection member to the second connection member. The spacing member or transport member flexes and twists during connection. The medical canister connector may also help organize one or more pressure-sensing conduits. Methods are also presented. | 05-01-2014 |
