luuf4aob TEDMED Sold to Jay Walker, Richard Saul Wurman Says AdiosThere’s been a bit of a shake-up at our favorite medical conference, TEDMED. It appears that TEDMED owner Marc Hodosh has sold the conference to an entrepreneur, inventor, founder of Priceline.com, and TEDMED speaker Jay Walker, who is currently the Chairman of Walker Digital, an R&D firm with interest in health and medicine, among many other pursuits.
This afternoon, TEDMED attendees were sent the following email from Richard Saul Wurman, the founder of both TED and TEDMED, expressing his disappointment with the way the sale transpired and his announcement that he will no longer be involved in the conference in any way. At previous conferences, Richard and Marc co-moderated the event in a dynamic partnership.
In his note, Richard describes the intention for the new TEDMED to be “a mega-event, rather like a medical Davos.” This year, TEDMED will still be held in San Diego but plans are to move it to Washington DC in 2012.

Friends of TEDMED, sponsors (profit and particularly non-profit), conferees, personal friends, presenters and service providers,
On the advice of counsel and because I feel it is my moral and ethical responsibility to all of you who have given me and TEDMED the benefits of your enthusiasm, energy, brilliance and financial support, without which I would never have been able to produce this or any conference, I am writing to inform you that Mr. Hodosh, to whom I entrusted TEDMED, has sold the conference to Mr. Walker for $16 million with future additional payments of as much as $9 million, and options to Mr. Walker’s new company, TEDMED LLC. I will have no further involvement of any kind with TEDMED. This was finalized without my concurrence while I was away on spring holiday with my wife and grandchildren.
You are all smart people and I don’t think I need to breast-beat or vent what has led me to this very difficult and painful decision (though I am sorely tempted). Let it suffice to say that the way in which this deal was made and their plans for the future of the conference have made it impossible for me to continue to participate.
I have been informed by Mr. Walker and Mr. Hodosh in separate conversations that this year’s TEDMED will be the last one in San Diego at the beautiful Hotel Del Coronado. Next May it will move to the Washington, D.C. area and morph into a mega-event, rather like a medical Davos. I point you to a New York Times article written by Andrew Ross Sorkin which gives the flavor of that event:
http://dealbook.nytimes.com/2011/01/24/a-hefty-price-for-entry-to-davos/?scp=2&sq=DAVOS&st=cse
This is completely alien to the spirit and passion with which TEDMED has thrived, and not in any way a form that has interest to me. In fact, it is the antithesis of what I believe made TED, when I created it, TEDMED, and the eg conference, unique and magical. The Washington event will even have formal dress balls in the evening.
So, if life is full of curve balls, I now have my catcher’s mitt on and I want to take this opportunity to express my deepest thanks to all of you for all you have given to me and the conference, and to let you know that I will be back in touch with you soon regarding, what I do think, will be the new direction for gatherings (as an alternative, not a replacement to the old form), a mold-breaking, new kind of communication that I have been contemplating for the last year and is now very close to being ready to announce.
It is called WWW.WWW and it will occur in September 2012 as a live and quite affordable iPAD enterprise app. It will combine a small live audience with pairings of various combinations of the 100 greatest minds of the twenty-first century in improvised conversations addressing the key W words such as the World, Weather, Water, War, Well-being, Wealth, the Web, Wit; I think you get it. Intellectual jazz.
I do hope to see all of you again on this and other future adventures.

We’ve reached out to the new TEDMED team, and a representative for Mr. Walker sent us the following statement:

Statement of Jay S. Walker, Chairman, TEDMED
On behalf of the new owners of the TEDMED conference, we are surprised and saddened that Richard Saul Wurman has chosen to part company with TEDMED. Richard has been a pioneer and a leader in the development of TEDMED, and we are disappointed that the sale of the company didn’t occur the way he had hoped.
We are also disappointed that his disagreement with our future plans for TEDMED would lead him to reveal information given to him on a confidential basis as part of over four months of negotiations to provide for Mr. Wurman’s future role in TEDMED.
We are big believers in the future of TEDMED, and our substantial investment backs that up. TEDMED is far more than simply an annual conference. It has become one of the world’s most important gatherings for the best thinkers and innovators in medicine worldwide.
Our commitment is to grow TEDMED and to make it even more important to the world of medicine. Richard is correct when he says our desire is to make TEDMED the medical equal to the World Economic Forum held in Davos. We admire the contribution that Davos makes to enhanced global economic thinking. Our goal is to provide all members of the TEDMED community with a program that focuses on innovation and leads in the discussion of medicine’s future progress and transformation.

cf9dpdxm Metal Organic Framework Molecules Help Make Gas Trapping Clothes
A Cornell undergraduate student used novel university-developed fabric, made of metal organic framework molecules (MOFs) and cellulose fibers, to design a face mask and a hoodie that can provide protection against poisonous gases. The MOFs are able to trap gas molecules of predefined size, determined in advance during fabric manufacturing, allowing for fabrics targeted at specific applications.

MOFs, which are clustered crystalline compounds, can be manipulated at the nanolevel to have cages that are the exact same size as the gas they are trying to capture, said Jennifer Keane ’11, a fiber science and apparel design (FSAD) major in the College of Human Ecology.
Keane worked with Hinestroza and fiber science postdoctoral associate Marcia Da Silva Pinto to create the gas-absorbing hood and mask. Some of the basic science behind this project was funded by the U.S. Department of Defense.
"The initial goal of attaching the MOFs to fibers was sponsored by the Defense Threat Reduction Agency. We wanted to harness the power of these molecules to absorb gases and incorporate these MOFs into fibers, which allows us to make very efficient filtration systems," Hinestroza said.
Da Silva Pinto first created MOF fabrics in Hinestroza’s lab, working in collaboration with chemists from Professor Omar Yaghi’s group at the University of California-Los Angeles; Yaghi is one of the pioneers and leaders of MOF chemistry, said Hinestroza.
At first the process did not work smoothly. "These crystalline molecules are like a powder that cannot easily become part of cloth," Da Silva Pinto noted. After months of trying to attach the particles to the fiber, the researchers realized that, "The key was to bring the fiber to the particle … It was a real paradigm shift," she said.
"Now we can make large surfaces of fabric coated with MOFs, and we are looking at scaling up this technology to nanofibers," said Hinestroza. "This type of work would only be possible at a place like Cornell where you have this unique merging of disciplines, where a fashion designer can interact easily with a chemist or a materials scientist."

vtjqrxlv Asantes Cartridge Based Pearl Insulin Pump Gets CE Marked
While the continuous delivery provided by an insulin pump allows for better control of blood sugar levels than multiple daily injections, currently available insulin pumps use a reservoir that requires frequent refilling. Sunnyvale, CA based Asante Solutions, Inc. hopes that its Pearl Insulin Pump will solve this problem, while still providing the same advantages as existing insulin pumps. The Pearl uses an insulin cartridge instead of the traditional reservoir, which the company claims will make refilling much quicker and more convenient for patients. The Pearl Insulin Pump received the CE mark this week, and is currently awaiting 510(k) clearance from the FDA.
More about the product:

The Pearl Insulin Pump is designed to simplify diabetes care for the more than 500,000 people worldwide who use an insulin pump and those considering insulin pump therapy. Unlike the insulin pumps currently available, which require users to manually fill an insulin reservoir using a vial of insulin and syringe, the Pearl Insulin Pump uses a 300-unit, pre-filled insulin cartridge that simplifies the process of loading the pump and filling the infusion set by reducing the number of steps required and thereby creating a less time-consuming and more convenient process.

zzeb7urg Covidien DuraSeal Exact Gets U.S. Green Light
Covidien has just announced that FDA gave its approval for the company’s DuraSeal Exact spine sealant, a device designed to help to fix teared dura during spinal surgeries. The material was developed for quick setting so as to prevent unnecessary leaking of spinal fluid, and comes in attractive blue so as to be easily seen when applying.

DuraSeal Exact spine sealant was shown in clinical trials to deliver an intra-operative watertight seal of the dura, in the per protocol population, 100% of the time.1 In contrast, the control group, treated with standard methods of dural closure including fibrin sealants, achieved an intra-operative watertight seal only 79% of the time.
DuraSeal Exact will be launched this quarter and follows Covidien’s 2009 launch of DuraSeal spine sealant, the only dural spine sealant approved by the FDA. The compound is a 100% synthetic absorbable hydrogel that provides excellent tissue adherence and a consistent watertight seal around the dura.
DuraSeal Exact spine sealant is formulated with a lower molecular weight than its predecessor, resulting in decreased post-application swelling and allowing surgeons to confidently use the product in spinal surgery. The product is absorbed over a 9-12 week time period, demonstrating a much longer persistence than fibrin glues.
The DuraSeal Exact spine sealant is designed to be a quicker solution than conventional sealing methods for surgeons who are faced with a sutured dural tear, occurring in approximately 10% of all spinal surgeries.3 The self-contained hydrogel takes only two minutes to prepare for use and three seconds or less to set, so surgeons can quickly complete an intra-operative seal. In addition, DuraSeal Exact spine sealant’s distinctive blue colorant provides excellent visualization to the surgeon to immediately confirm coverage and thickness of the seal, on the target application site.

brghddhm Students Create Eye Tracking Tablet For Those With Disabilities
Engineering students at Brigham Young University have developed a computer setup that can be controlled with a person’s eye movements. The system measures 2 inches thick, 10 inches long and 14 inches wide, runs the Windows 7 operating system, and costs under $1,500.
The product was a result of a collaboration with Mesa, Arizona based EyeTech Digital Systems, a company that develops eye-tracking hardware and software.
Because the cost of the BYU eye-tracking computer is low compared to commercial systems that can cost upwards of $14,000, the unit can be targeted to people with disabilities in parts of the world that can’t afford more expensive eye-tracking systems.

0415 WRIST RiceWrist Robot Exoskeleton Assists in Rehab for Spinal Cord Injury VictimsEver since it was discovered that the human brain isn’t “hard-wired” and can overcome the paralyzing effects of a stroke or spinal-cord injury with intense rehabilitation, much in the area of robotics has been devoted to restoring limb movement to victims of a stroke or spinal cord injury. The latest, from Rice University in Houston, Texas, appropriately called the “RiceWrist”, was designed to help people with spinal cord injury restore movement in the arm.
The RiceWrist is a fully articulated exoskeleton that mimics the joints of a limb from the shoulder to the hand. It works by assisting the user in performing specific arm movements; any difficulty with moving one’s arm during rehab will cause the RiceWrist to gently kick in and move the arm in the desired direction. RiceWrist monitors the patient’s progress through the entire regimen, adjusts its level of assistance accordingly, and, eventually, will stop assisting altogether as movement improves.
RiceWrist so far has only gone through a single-patient trial, but this one patient, a 24-year old motocross professional who crushed his vertebra in an accident, has shown that the robot has much potential. After only two weeks, the patient was already able to smoothly perform tasks such as turning over cards and picking up coins.
Take a look at the video of RiceWrist in action:
