A customizable wound treatment system for treating multiple zones of a wound includes a dressing configured for use with a first zone and a second zone of a wound that includes a first foam layer placed over the first zone, a second foam layer placed over the second zone, a first drape layer disposed over the first foam layer and beneath the second foam layer, and a second drape layer disposed over the second foam layer. The customizable wound treatment system includes a negative pressure source pneumatically coupled to the first foam layer and the second foam layer and operable to create a negative pressure at the first zone and the second zone and a fluid instillation pump fluidly coupled to the first foam layer and configured to instill a treatment fluid to the first zone.

Percutaneous access devices (PAD), bandages, or other implantable medical devices are provided that are equipped with filters, environmental controls, and sensors that promote the formation of a natural biologic seal between the skin and the device to form a barrier to microbial invasion into the body. Levels of humidity and pressure are monitored and dynamically controlled to optimize wound closure about an implanted device or when a PAD is not present a wound itself. Methods and systems for actively assessing wound closure are incorporated into the design of percutaneous skin access devices (PAD), bone anchors, or a wound dressing or bandage alone without at PAD. Pressure and humidity sensors provide active feedback for making changes to the ecology of the wound site or PAD insertion site. A filter is used to aerate the wound while also preventing pathogens in the ambient air from reaching the wound.

A method and apparatus are disclosed for dressing a wound. The apparatus comprises an absorbent layer for absorbing wound exudate, a liquid impermeable, gas permeable filter layer over the absorbent layer, a cover layer comprising at least one orifice and a first liquid and gas permeable transmission layer underlying the absorbent layer. The transmission layer is in fluid communication with the filter layer.

Some embodiments comprise a pump assembly for reduced pressure wound therapy, comprising a housing, a flow pathway through the pump, one or more valves in communication with the flow pathway, a pump supported within or by the housing, and a one-way flow valve in fluid communication with the pump. The pump assembly can have a pressure sensor in communication with the flow pathway through the pump, and at least one switch or button supported by the housing, the at least one switch or button being accessible to a user and being in communication with the controller. The one-way flow valve can be configured to substantially prevent a flow of gas through the one-way flow valve in a direction of flow away from the pump. The pump assembly can have a controller supported within or by the housing, the controller being configured to control an operation of the pump. The pump has been sterilized following the assembly of the pump such that an inside and an outside of the housing, the flow pathway, the one or more valves, the pump, the controller, the battery compartment, and the at least one switch or button have been sterilized.

Systems, apparatuses, and methods for providing negative pressure and/or instillation fluids to a tissue site and sensing properties of fluids at a tissue site are disclosed. Systems, apparatuses, and methods for wirelessly activating and pairing a sensing device with a wireless communication device and/or therapy device to transfer sensor data from the tissue site is also disclosed.

A negative pressure device includes a drape covering a dressing site on a patient, a sealing element connected with the drape, a flexible gas chamber housing disposed outwardly from the drape with respect to the enclosed chamber, and a reactor. The drape is made from a thin sheet film and is capable of maintaining a negative pressure underneath the drape. The sealing element and the drape are configured so that the sealing element cooperates with the drape to define an enclosed volume covered by the drape and surrounded by the sealing element when applied to skin. The flexible gas chamber housing defines a flexible gas chamber. The reactor is positioned with respect to the enclosed volume and the flexible gas chamber to consume a gas found in air within the enclosed volume and the flexible gas chamber.

System for percutaneous drainage of a drainage site includes a catheter, a drain tube, a first pump, a flush tube, a second pump, and a controller. The catheter includes a drain lumen defined by a first portion of a catheter wall and a septum, and a flush lumen defined by a second portion of the catheter wall and the septum. The flush lumen is separated from the drain lumen by the septum. The septum has at least one septal hole disposed therein such that the drain lumen and the flush lumen are in communication via the at least one septal hole. The catheter wall has at least one wall hole disposed therein such that the drain lumen is in communication with the drainage site when the distal end portion of the catheter is placed within the drainage site.

A Negative Pressure Wound Therapy (NPWT) dressing having a sealing layer on a non-wound interfacing surface. Such a sealed surface eases application and reduces the risk of a loss of seal once applied to a patient. Associated adaptors and couplers, which may be universal couplers, allow for simplified use of the disclosed and existing dressings. An optional pressure regulator unit may use existing wall suction available in medical facilities; it may interface with a transportation unit. Embodiments of the regulation unit provide for various monitoring, operation and alarming features that may be accessed using mobile wireless, wireless LAN, and internet based connectivity approaches.

A method and apparatus are disclosed for dressing a wound.
