Abstract: Systems, kits, methods of manufacturing, and a sealing member for creating a sealed space are described. The sealing member can include a film layer and a first adhesive layer coupled to the film layer. The sealing member can also include a second adhesive layer coupled to the first adhesive layer. A plurality of apertures may extend through the second adhesive layer. Each aperture can expose at least a portion of the first adhesive layer through the second adhesive layer. A plurality of polymer particles may be disposed in the first adhesive layer. The polymer particles can be configured to dissolve in response to interaction with a switching solution.

Abstract: Systems, methods, and connectors are provided that introduce a working gas at certain times into a reduced-pressure dressing into order to break or avoid vacuum locks in the conduits removing fluids. In one instance, a reduced-pressure connector includes a connector body for applying a reduced pressure to the tissue site. The connector body is formed with a venting port, a body conduit, and a receptacle to receive a reduced-pressure delivery conduit. The reduced-pressure connector includes a flexible member coupled to the connector body over the venting port. The flexible member is formed with at least one venting aperture. The flexible member is biased away from the venting port and is configured to collapse and seal the venting port under a reduced pressure greater than a threshold pressure. Other systems, apparatuses, and methods are disclosed.

Abstract: Methods, devices and systems are disclosed for generating and harvesting skin grafts having improved properties and for ensuring efficient and consistent blister formation and/or reducing patient harm and discomfort. In one aspect, the invention infuses a fluid into skin tissue at the donor site to enhance blister formation. The fluid infusion can occur before or after application of negative pressure—or can be cyclically applied before or after repeated applications of negative pressure.

Abstract: An adapter for providing fluid communication with a tissue site may include a base, a conduit housing, a primary port, at least one ancillary port, and at least one port extension. The base may define a mounting plane having a first planar side and a second planar side opposite the first planar side. The conduit housing may be supported by the base and may include a recessed region defining an entry surface. The conduit housing and the recessed region may be positioned on the first planar side with the entry surface facing the first planar side. The primary port may be on the entry surface, and the at least one ancillary port may be on the entry surface. A distal end of the port extension may be positioned on the second planar side in fluid communication with the ancillary port. Other devices, systems, and methods are disclosed.

Abstract: Illustrative embodiments of a dressing for treating a tissue site may include a fluid transport layer, an offloading layer, and a liquid deflector. The offloading layer may be in fluid communication with the fluid transport layer, and the offloading layer may include a force offloading region and a target region. The liquid deflector may be positioned between the fluid transport layer and the offloading layer. The liquid deflector may be configured to deflect a liquid from the tissue site into contact with the target region of the offloading layer. The target region may be configured to expand for offloading forces at the tissue site. Other dressings, systems, and methods are disclosed.

Abstract: Systems and methods are provided for moving fluids from a patient to a canister and lowering or eliminating the bio-burden of the canister. In one instance, a method for removing fluids from a patient includes using reduced pressure to remove fluids from a patient, delivering the fluids into a reduced-pressure conduit and into a fluid reservoir, exposing the fluids removed from the patient to a UV light source to kill pathogens to create disposable fluids, and disposing of the disposable fluids. Other systems, devices, and methods are presented.

Abstract: Systems, methods, and apparatuses are presented that facilitate the provision of reduced pressure to a tissue site by using a delivery-and-fluid-storage bridge, which separates liquids and gases and provides a flow path for reduced pressure. In one instance, a delivery-and-fluid-storage bridge includes a delivery manifold for delivering reduced pressure to a treatment manifold at the tissue site and an absorbent layer proximate the delivery manifold adapted to receive and absorb liquids. The delivery manifold and the absorbent layer are encapsulated in an encapsulating pouch. A first aperture is formed proximate a first longitudinal end of the delivery-and-fluid-storage bridge for fluidly communicating reduced pressure to the delivery manifold from a reduced-pressure source, and a second aperture is formed on a patient-facing side of the delivery-and-fluid-storage bridge. Reduced pressure is transferred to the tissue site via the second aperture. Other systems, apparatuses, and methods are disclosed.

Abstract: A system for treating a tissue site includes a reduced-pressure source to apply reduced pressure, a manifold in fluid communication with the pressure source to provide reduced pressure to the tissue site, and a drape for adhering to the tissue site to cover the tissue site and the manifold. The drape includes an adhesive layer for sealing the drape to the tissue site to create a sealed space having the manifold therein, and a non-adhesive layer formed from a portion of the adhesive layer. A method for manufacturing a medical drape includes providing a sheet of adhesive material and treating a side of the sheet of adhesive material to form a non-adhesive layer and an adhesive layer. The method laminates a release liner adjacent the adhesive layer.

Abstract: A sealing system that includes a switchable drape is presented. The drape provides enhanced sealing by using a high-strength adhesive. In one instance, the switchable drape has a plurality of perforations through which a switching solution may be delivered to the high-strength adhesive. The switching solution causes the high-strength adhesive to become less adhesive so that the switchable drape may be removed more easily. Other systems, methods, and drapes are presented.
