In Australia, scientists battle chronic pain with smart chip

By | December 22, 2010, 6:44 AM PST

Researchers in Sydney, Australia have developed a smart chip that can block pain signals from traveling to the brain.

The chip, which is designed to be implanted in the spinal cord, was developed by biomedical, electrical and mechanical engineers at National ICT Australia.

The idea isn’t to block all pain signals; rather, it’s to dial down the effects of chronic pain. Embedded in a biocompatible device, the chip — smaller than the head of a match — can measure the properties of the nerves that carry pain signals to the brain, then emit a 10-volt electric pulse to block them.

Our cousins at ZDNet Australia report:

A couple of the devices are sewn into a 1.22mm wide micro-lead made from polymer yarn and electronic wires. The wires are then inserted into the spine (or elsewhere) and connected to a device containing a battery and a computer processor. The battery can be charged wirelessly.

Voila: the brain never gets the memo.

The device isn’t the first of its kind, but it’s the first to be so small. Conventional devices are the size of a matchbox, making implantation a bit difficult, as such a device requires longer connection leads and must be placed further away from the spine.

Applications for the device include chronic back, neck and leg pain, as well as those suffering from migraines, Parkinson’s disease or epileptic seizures.

The technology will be commercialized by Saluda Medical.

But there’s still an elephant in the room: the fact that the device treats the symptom, not the problem.

Therefore, the question: is an elaborate, expensive solution to only symptoms worth it?

Wonderful initiative. Great Teamwork!! One day, if we have medicine for hunger and thirst, half of these world's issues would be solved. Please work on this great cause too..

I think that this kind of medical technology is great, potentially
eliminating a lot of unnecessary long term suffering. However,
maybe we should all (re)read Michael Crichton's "The Terminal
Man" while we're so enamored with the great technology?

This sounds like a cousin of the TENS unit ( T ranscutaneous E lectrical N erve S timulation) that I used for several years in the early 1980's for chronic/severe back and neck pain after an automobile accident. As a result, I was able to actively participate in physical therapy, eventually get off all prescription pain meds (after 2 years of particularly nasty stuff), and return to normal life. In fact years later, I successfully used it during labor and delivery with the support of an enlightened OB/GYN.

As far as the question: "the fact that the device treats the symptom, not the problem" - sometimes chronic pain is the problem after the original injury or condition heals or is resolved.

The answe is yes, it's worth it. Currently the medical establishment will medicate you into oblivion, or give you enough sympathetic spinal blocks to get you by for a year or two if you're incredibly fortunate. Neither of those options do anything but treat symptoms and don't take care of the issue. I know, I've been thru these for years. Until the cure is found for why the signals are over-firing in chronic pain sufferers in the first place, something viable and long term has to be researched and developed. Good on ya Mates!

Almost anything to kill severe pain
If there are little or no side effects, this certainly beats implantible PCA's (Patient Controlled Anesthetics) and would be much cheaper in the long run. What they need to do, is to develop a unit that can be placed externally.

RE: In Australia, scientists battle chronic pain with smart chip
As every question of effectiveness is answered, "It depends."

In the same issue of Smart Planet is an article on preventing/curing hospital acquired infections. My dear relative, as an example of 1, acquired spinal infection from needles being inserted in the spine to deaden (locate) specific nerve blocking site. Hospital treatment produced alleged remission before leaving to nursing care for rehab, where death occurred from MRSA acquired in the hospital.

So, while invention of a micro-spinal pain block is a wonderful thing, breaking the first line of defense (skin) to properly locate or install it is not. The "next big thing" has to be precision non-invasive diagnostics, because bacteria and viruses don't care how small the device is; it's the opportunistic skin opening in a non-sterile environment that matters to them.
