Nanotubes are easily grown to be vertically aligned
The NanoPortalTM implant design is simple, elegant, and space-efficient. The passive delivery mechanism eliminates the additional components and failure modes present in mechanical alternatives. The small device size enables insertion by syringe needle, resulting in a quick and easy outpatient procedure.
Made from titanium, titania and silicone, the NanoPortal implant is optimized for biocompatibility. The NanoPortal implant is in preclinical development and is currently not used in any human studies or clinics.
A hermetic seal is created without any adhesives, producing a device with only titanium, titania, and silicone.
The NanoPortal membrane is attached at the end of a drug-filled titanium reservoir such that the therapeutics exit through the nanotubes.
Since the rate-limiting function of the device is accomplished by the thin NanoPortal membrane, the interior space consists entirely of medication formulation.
With the majority of the device devoted to drug, extended treatment durations can be achieved by a small device.
