| 20100030166 | MANUALLY-ACTUATED, REDUCED-PRESSURE SYSTEMS FOR TREATING WOUNDS - A manually-actuated, constant reduced-pressure apparatus for use with a reduced-pressure system for treating tissue at a tissue site includes a flexible, collapsible member that is operable to move between a compressed position and an extended position. The collapsible member may be disposed between a carrier member and a slider member that move between a compressed position and an extended position. The carrier member and slider member are urged away from each other by a constant-force biasing member, e.g., a constant force coil spring. As the apparatus moves from the compressed position to the extended position, a constant reduced-pressure is generated and delivered to a reduced-pressure port. Systems, methods of manufacturing a manually-actuated, constant reduced-pressure apparatus, and methods of treating a tissue site are also provided. | 02-04-2010 |
| 20100160874 | REDUCED-PRESSURE WOUND TREATMENT SYSTEMS AND METHODS EMPLOYING MICROSTRAIN-INDUCING MANIFOLDS - Microstrain-inducing manifolds, systems, and methods are presented that involve microstrain-inducing manifolds that include a plurality of shaped projections for creating microstrain. The shaped projections may be tapered projections. A system may include a sealing member for placing over the tissue site, a microstrain-inducing manifold, and a reduced-pressure subsystem that delivers reduced pressure to the sealing member. The reduced pressure causes the shaped projections to create microstrain at the tissue site. Other methods, apparatuses, and systems are also presented. | 06-24-2010 |
| 20100160876 | REDUCED-PRESSURE WOUND TREATMENT SYSTEMS AND METHODS EMPLOYING MANIFOLD STRUCTURES - Manifold structures, systems, and methods are disclosed that include using longitudinal members and one or more shaped projections to cause microstrain at a tissue site. In one instance a manifold structure includes a plurality of spaced longitudinal members and at least one shaped projection coupled to at least one of the plurality of longitudinal members for creating a microstrain at a tissue site. The at least one shaped projection includes a columnar member having a distal end and includes an enlarged member positioned at the distal end of the columnar member. The columnar member has a first outer diameter (D | 06-24-2010 |
| 20100168654 | APPARATUSES, SYSTEMS, AND METHODS FOR MANAGING LIQUID FLOW ASSOCIATED WITH A TISSUE SITE USING THE PRESENCE OF REDUCED PRESSURE - The illustrative embodiments described herein are directed to apparatuses, systems, and methods for managing liquid flow associated with a tissue site that involves using reduced pressure to control fluid flow. In one instance, an apparatus includes a first valve and a second valve in fluid communication with a reduced-pressure source. The valves are movable between an open position and a closed position and are operable to change flow status (open to closed or vice versa) based on a presence of reduced pressure. At least one of the first valve or the second valve is in the closed position to obstruct a flow of a liquid while the other is in the open position. The apparatus also includes a reservoir fluidly coupled to the first valve and the second valve. Other systems, methods, and apparatuses are presented. | 07-01-2010 |
| 20110066123 | MEDICAL DRESSINGS, SYSTEMS, AND METHODS EMPLOYING SEALANTS - According to an illustrative embodiment, a system for treating a wound at a tissue site of a patient comprising a reduced-pressure source to supply reduced pressure, a drape adhering to the tissue site to cover the wound where possible leak passages between the drape and the tissue site may occur, and a seal disposed between the drape and the tissue site, is disclosed. The seal is adapted to react with a fluid to form a sealant substantially filling the passages in response to air leaking through the passages from outside the drape when reduced pressure is applied to the wound. According to another illustrative embodiment, a method for sealing a drape to a tissue site for treating a wound at the tissue site comprising applying the drape to cover the tissue site whereby passages are formed between the drape and the tissue site, positioning a seal between the drape and the tissue site wherein the seal is adapted to react with a fluid to form a sealant for substantially filling the passages, is also disclosed. | 03-17-2011 |
| 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 |
| 20110178481 | Wound-Connection Pads For Fluid Instillation and Negative Pressure Wound Therapy, and Systems and Methods - Connection pads for coupling fluid-instillation and negative pressure wound therapy (NPWT) apparatuses to wound dressing, and methods and wound dressings for breaching a drape after coupling a wound dressing to a fluid-instillation and/or NPWT apparatus. | 07-21-2011 |
| 20110257613 | EVAPORATIVE BODY-FLUID CONTAINERS AND METHODS - Body-fluid containers, methods, and systems are presented that include a container that has a container housing formed, at least in part, by a liquid-impermeable, vapor-permeable material. The liquid-impermeable, vapor-permeable material allows water to evaporate and be transmitted outside of the container. The evaporation allows more fluid to be processed by the container than the container could otherwise hold. Other systems, methods, and apparatuses are presented. | 10-20-2011 |
