Dressings for use in negative pressure therapy and methods of making the dressings are provided herein. The dressings may comprise at least two layers in a stacked configuration. The first layer may comprise a manifold layer and the second layer may comprise a silicone gel layer. The second layer may have perforations to form fluid restrictions that can open and close when used in negative pressure therapy. The perforated second layer may be formed by a first and a second curing step.

Composite dressings for improved granulation and reduced maceration with negative-pressure treatment

As an example, in some embodiments is a dressing that may comprise a manifold, a bioresorbable component, and a degradation-modulating component. The degradation-modulating component may cover two or more surfaces of the bioresorbable component. The degradation-modulating component may be further configured to modulate degradation of the bioresorbable component.

Extended wear-time dressing

A negative pressure wound therapy system includes a wound dressing, at least one pump fluidly coupled to the fluid interface, a pressure sensor fluidly coupled to the wound dressing, a control housing, and an electrical coupler. The wound dressing includes a sealing layer, an absorbent layer adjacent to the sealing layer, and a fluid interface attached to at least one of the sealing layer or the absorbent layer. The at least one pump is configured to apply negative pressure to the fluid interface to draw fluid from the wound dressing via the fluid interface. The pressure sensor is configured to detect a fluid pressure of the wound dressing. The control housing is remote from the wound dressing. The electrical coupler is configured to removably connect the control housing to the at least one pump.

Distributed negative pressure wound therapy system incorporating an absorbent dressing and piezo-electric pump

A fluid delivery system, method, and apparatus for providing instillation therapy with a negative-pressure source is described. The apparatus includes a housing having an ambient chamber and a negative-pressure chamber fluidly isolated from each other. The apparatus also includes a moveable barrier disposed in the housing between the ambient chamber and the negative-pressure chamber. The moveable barrier is operable to move between a charge position and a discharge position in response to negative pressure. A fluid source is disposed in the negative-pressure chamber and is collapsible in response to movement of the moveable barrier to the discharge position. The apparatus also includes a fluid outlet in fluid communication with the fluid source, a negative-pressure port in fluid communication with the negative-pressure chamber and configured to be coupled to a negative-pressure source, and a vent formed in the housing and fluidly coupled to the ambient chamber.

Instillation cartridge for vacuum actuated fluid delivery

A dressing for treating a tissue site may include a base layer, a sealing member, a first and a second wicking layer, and an absorbent layer. The base layer may have a periphery surrounding a central portion and a plurality of apertures disposed through the periphery and the central portion. At least one of the apertures in the periphery may be positioned at an edge of the periphery, and may have an interior exposed at the edge. The sealing member and the base layer may define an enclosure. The first and the second wicking layer may each be disposed in the enclosure with the absorbent layer positioned between the first and the second wicking layer. Other dressings, systems, and methods are disclosed.

Dressing with sealing and retention interface

A releasable medical drape, and systems and methods having the same, includes at least a liquid-impermeable, vapor-permeable layer, a pressure-sensitive adhesive layer, and a soft-gel layer having a plurality of apertures. The soft-gel layer is configured to be disposed adjacent to a tissue site. A portion of the pressure-sensitive adhesive layer extends through the plurality of apertures in the soft-gel layer to contact the tissue site. The soft-gel layer forms a good seal with the tissue site and the pressure-sensitive adhesive layer extending through the plurality of apertures forms a firm—but releasable—coupling with the tissue site.

Releasable medical drapes

Systems, methods, and apparatuses for irrigating a tissue site are described. The system can include a tissue interface and a sealing member configured to be placed over the tissue site to form a sealed space, and a negative-pressure source fluidly coupled to the sealed space. The system includes an irrigation valve having a housing, a piston disposed in the housing, a fluid inlet to fluidly couple a fluid inlet chamber to a fluid source, and a fluid outlet to fluidly couple a fluid outlet chamber to the sealed space. A piston passage extends through the piston and fluidly couples the fluid inlet chamber and the fluid outlet chamber, and a biasing member is coupled to the piston to bias the irrigation valve to a closed position. The negative-pressure source is configured to move the piston between the closed position and an open position to draw fluid to the sealed space.

Apparatus for negative-pressure therapy and irrigation

A negative pressure wound treatment (NPWT) system including a NWPT therapy unit and a wound dressing configured to overlay a wound bed. The NPWT system includes a first length of tubing comprising a first end and a second end, the first end of the first length of tubing coupled to the NWPT therapy unit and the second end of the first length of tubing having a first coupling half, as well as a second length of tubing having a first end and second end, the first end of the second length of tubing coupled to the wound dressing and the second end of the second length of tubing having a second coupling half. The NPWT system includes an inline filter comprising a sintered polymer and a superabsorbent material, and an inline coupling, wherein the inline coupling is configured to operably couple and de-couple the NPWT therapy unit and wound dressing.

Fluid ingress protection for NPWT device

A medical drape for use with a reduced pressure system for providing reduced pressure to a tissue site is described. In some embodiments, the drape may include a flexible film, and an adhesive layer coupled to the flexible film. The adhesive layer may include a first adhesive disposed on a first portion of the flexible film in a first pattern. The first adhesive can be configured to secure the flexible film proximate to the tissue site. The adhesive layer generally includes a second adhesive disposed on a second portion of the flexible film in a second pattern. The second adhesive can be configured to seal the flexible film proximate to the tissue site. The first pattern and the second pattern are preferably registered so that the first portion and the second portion are offset to cover substantially different portions of the flexible film.

Medical drape with pattern adhesive layers and method of manufacturing same

In some examples, provided is a fluid blockage device for use with a reduced-pressure source for treating a tissue site with reduced pressure. The fluid blockage device may be configured to preclude fluid communication through a port fluidly coupled to the reduced-pressure source when the fluid blockage device contacts a liquid. Other devices, systems, and methods are disclosed.
