Robotic Prostheses For Human Faces 111

holy_calamity writes "New Scientist reports on a patent application that suggests implanting polymer muscles beneath the skin of people suffering paralysis of the face to give them control of their features. The technique has already been used successfully to reanimate the eyelids of human cadavers. Movement could be returned to other facial features and even paralyzed limbs in the same way, the surgeons at University of California Davis say. The full patent application is also available on the WIPO site."

      Partial facial paralysis hasn't done anything to Harm Sylvester Stallone's career.

      Or the rest of Hollywood, for that matter. Cosmetic paralytics like botox give the appearence of fewer wrinkles and stop microexpressions from giving away lies or other unpleasant emotions [], which is funny because they often cause a zombie-like facial expression. See: FoxNews.

      Humans are striving to give facial movement to corpses while they give away their own facial expressions to look like corpses.

    The technique has already been used successfully to reanimate the eyelids of human cadavers.

    Hmmm. I had no idea that cadavers had the capacity to control robotic eyelids :)

    From the abstract:

    Metbods: With use of four cadaver heads, an extended upper and lower blepharoplasty incision was used to secure an upper and lower expanded polytetrafluoroethylene implant in the medial orbital wall and tarsal plates. The slings were passed through a hole drilled in the lateral orbital wall or around a titanium screw. Lateral pull on the sling created eyelid closure, and the necessary distance of pull was measured. Results: The eyelid sling mechanism functioned to achieve complete eyelid closure. Less tension was required for eyelid closure when the sling was placed in both eyelids (3 mm of pull instead of 6 mm). Conclusions: The application of artificial muscle to a range of problems that affect both patient morbidity and quality of life is promising. Eyelid closure was created in a cadaver model using a novel sling, but future studies will need to address the feasibility of a prototype artificial muscle eyelid device in humans.

    Since when are surgical procedures patentable? And what are the ethics of patenting this anyway, and likely thereby preventing some people from receiving such treatment, even if it is somehow legal to do so?

    Or is the patent specific to the artificial muscles?

And we'd have an exact description of how to do it ourselves too, instead of still having to guess at it. As it is, the old fart is keeping it all a trade secret, which is just what patents were supposed to prevent.

      Note that it's a patent application. I haven't looked to see if it's patentable, but you can file applications for things that aren't patentable.

      The concern about ethics really depends on what control is exerted with the patent. It'd all be speculation, since this isn't even a procedure ready to be used. (For drugs, for example, intellectual property controls back the majority of the drug cost -- so there are reasonable ethical questions. Even with a zero cost due to IP, neither robotic prosthesis nor the s

      The only people who would be prevented from receiving such a treatment are people who will have nothing to do with patents at all, in which case they'd never even be in the hospital in the first place.

      • Yet the patent brief itself seems to lay claim to the process as well:

        This invention provides methods and devices for reconstructing muscular responses in patients with paralysis.

        Or am I reading too much into this use of the word "methods"? I rather hope I am.


    • Sorry to reply to myself, but here is the patent abstract, from the WIPO site linked in the posting:

      This invention provides methods and devices for reconstructing muscular responses in patients with paralysis. Electroactive polymer (EAP) actuators power implants attached to tissues in the patients. When the actuators are energized, the implants move the tissues appropriately to provide improved body functions to patients experiencing a paralysis or paresis.
