Thanks, bobjengr. Good to know your wife was able to receive the treatment she needed. It is my understanding that these are meant to replace the retina that isn't functioning properly. I'm a bit confused about your question about anti-rejection drugs? Thanks for reading and your comments.
Excellent post Elizabeth and very informative. I think this is fantastic technology and obviously tremendously beneficial to those with retina difficulties. My wife had a detached retina some years ago causing real problems. Fortunately laser surgery made the necessary repairs possible. Is the artificial retina used to replace the existing retina? Also, do you know if anti-rejection drugs work for this device in the same manner? This is a great example of how nanotechnology is improving our lives.
I am a design engineer by trade. My wife lost the central vision in her left eye because part of the retina died in an occular stroke. I have often wondered if someone was going to invent some sort of lens that could divert the light coming through the lens to other parts of the retina to give people like her vision back. This article on retina replacement if facinating. It gives hope that she may be able to regain sight again.
The terminology is wrong, not the science. Look up "solar" in the dictionary to understand the problem with the choice of word. Hence, "light powered" is correct, but "solar powered" is not -- unless the person happens to be viewing actual sunlight, e.g. "staring at the sun".
TJ McDerdermott. They said it is to replace rod and cone damage so is not part of a whole new artificial eye. Doing an entire eye would be really complicated. My previous posts were to the other 2 posters above yours, but hitting reply doesn't work.
EnteroMedics implants a device that sends messages into the stomach's vagus nerve to deal with obesity and is doing FDA trials now. The device affect the vagus nerve which messages the brain advising whether the stomach is full etc. The hope is the device can make the brain think the stomach is full when not and send messages to other parts of the body that respond when a person is hungry.
They have been at it for years so there is no answer yet if it will get a good outcome.
No mention of how the nanotubes will be connected to the nerves. My understanding of biological implants is that this is the point were most systems don't function well. Nerve connections for relativly simpler systems like artificial hands are not that great yet, and here were talking about nerves that connect to rods and cones.
Industrial trade shows, like Design News' upcoming Pacific Design & Manufacturing, deserve proper planning in order to truly get the most out of them as marketing tools. Here's how to plan effectively.
The series now can interface with a wider array of EtherNet/IP-compliant hardware across many industrial sectors, including factory automation systems, plastic injection molding apparatus, and materials-handling equipment.
