摘要：
A device for reducing agent penetration at an insertion site is provided that has a porous inner sleeve fluidly connected to a conduit. A vacuum or hydrodynamic source is fluidly connected to the conduit. The device is stabilized by fibroblast in-growth and inhibits bacterial colonization. A device is also provided that has a conduit having a bore and an outer conduit surface. The outer conduit surface is optionally nanotextured to promote fibroblast adhesion and limit bacterial residency. A sleeve is provided in fluid communication with the bore of the conduit, and is formed from materials characterized by a pore matrix through which vacuum or hydrodynamic draw is achieved in a process to promote stabilization and reducing bacterial colonization by draw fluid from an area around the surrounding the site of the device. The sleeve optionally has a distal nanotextured surface.
