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. |
