Abstract
This invention is a sleeve-like tissue-interface device designed to reduce the incidence of nosocomial infection related to percutaneous conduits by promoting a tissue seal where the conduit and skin interface, and by the expression of antibacterial activity to reduce the possibility of bacteria advancing along the conduit into deeper tissues. In particular, the positionability of the invention allows it to be placed onto a catheter-like device, in the dermal and subcutaneous tissue below the catheter exit site, although this position relative to catheter length is variable at different anatomical sites, and from patient to patient. The positionability feature also allows the invention to be used in conjunction with existing percutaneous access devices such as catheters and wound drains, as an optional measure against bacterial infection.
