Synthetic Vascular System
Say you had an artificial heart, pancreas, or liver and needed to refill its power or enzyme supply without cutting the body open to gain access. How would you do it?
Enter the synthetic vascular system: A device architecture designed to give external operators direct access to internal bodily functions and implants.
It would consist of a nanomanufactured (and therefore leak-proof), biocompatible, vein-sized tube lined with micromechanical pumps that move injected feedstock into or out of the channel and whatever it's connected to inside the body such as an internal organ, an implant, or otherwise.
Beyond the mechanical elements for moving fluid, the channel would be lined with sensors and nanomechanical elements including filters and nanopillars[1][2] designed to neutralize pathogens that might enter alongside the introduced agents. In effect, it's a synthetic vascular system complete with its own immune defences, providing direct access to implants, tissues, and organs.
The device's external opening would be a nozzle nanoprecisely (chemo-surgically) bonded to the patient's skin--an advancement of external inlets already in development today[3]. It would self-clean nanomechanically on a daily cycle, remain biocompatible, and where necessary include provisions for dampening the immune response associated with introducing a new permanent access point on the body.
