#Freedom Driver allows man with artificial heart to await transplant at home Heart failure patients awaiting organ transplants normally find themselves anchored to the hospital bed by a washing machine-sized device that keeps blood pumping through their veins.

and replacing it with an artificial organ a temporary solution that would keep him alive until another heart became available.

What drives power to Larkin's artificial heart and others like it is a machine that delivers compressed air into the ventricles via two tubes.

#A half-cow, half-electronic artificial heart has saved this Frenchman In France, A 75-year-old man has just been given the gift of life as a team of surgeons have completed successfully the transplant of the world s first true artificial heart.##

##The patient, so far unnamed, is reportedly recovering at Georges Pompidou European Hospital in Paris,

##Most other artificial hearts, by contrast, beat at a constant unchanging rate. This means that patients either have to avoid too much activity,

Patients who receive artificial heart transplants usually take anticoagulation medication to minimize such risks. Carmat artificial heart mimics the dual chamber pumping action of a real human heart.

The technology, which took 25 years to develop, started taking shape after the surgeon initially tested the feasibility of developing artificial heart valves using chemically-treated animal tissues as an alternative to plastic.

Since then he has obtained approval from authorities in France, Belgium, Poland, Slovenia and Saudi arabia to conduct human trials that are expected to run until the end of 2014.

Ultimately, the litmus test hinges on whether the artificial heart s pumps last more than a few years.

The#Syncardia#total artificial heart which remains the only FDA-approved heart replacement option, has made it

The artificial heart features sensors to monitor and adjust blood flow depending on the body s demands.

The idea was to develop an artificial heart in which the moving parts that are in contact with blood are made of tissue that is better suited for the biological environment,

The Carmat artificial heart is expected to cost about 140,000 to 180,000 Euros (or $191, 000 to $246, 000.

##Results from the latest clinical trials of his#smartphone-linked artificial pancreas#suggest he might just make that deadline.

The artificial pancreas performed well in#hospital-based clinical trials in 2010. But the important test is whether it works in a real-world environment.

It s fantastic that research on the artificial pancreas is forging ahead, both in the US and in the UK, says Alasdair Rankin, director of research at Diabetes UK,

The work addresses one of the lingering challenges in creating artificial organs for drug testing or

#FDA Approves First Retinal implant An article by Scientific American. The Food and Drug Administration (FDA) Thursday approved the first retinal implant for use in the United states. The FDA s green light for Second sight s Argus II Retinal Prosthesis System gives hope to those blinded

by a rare genetic eye condition called advanced retinitis pigmentosa, which damages the light-sensitive cells that line the retina.

The Argus II is not the only retinal implant under development. Retina Implant AG takes a slightly different approach by making a prosthetic inserted beneath a portion of the retina.

Stanford university researchers are in the early stages of developing self-powered retinal implants where each pixel in the device is fitted with silicon photodiodes.

eventually, artificial organs tailor-made for specific patients. Researchers have been able to engineer tissue samples in the past by combining artificial scaffold-like structures and animal cells.

The researchers designed a wearable artificial skin made out of tiny domes that interlock and deform when poked

They can be used in any application that we need to record electrical signals such as cardiac pacemakers

whether as artificial skin or electronic paper. Making such concepts affordable enough for general use remains a challenge

The artificial bones were made with a titanium powder which is used also in many other orthopedic implants.

for example, the artificial joints may eventually Break in addition, orthopedic surgeons currently have no suitable method for precisely measuring leg length before the operation

The new system was developed within the"artificial joints"cooperative network which is funded by the Federal Ministry for Economic Affairs and Energy (BMWI) and coordinated by Fraunhofer IWU.

#Automated captioning system processes hundreds of video-hours per day In 2008, four students at the MIT Sloan School of management developed a system for captioning online video that was far more efficient than traditional methods,

Depending on the domestic or imported artificial joints used, an operation costs about 50,000-100,000 RMB, something many families cannot afford.

The new material, termed lastomeric foam could potentially be used for prosthetic body parts, artificial organs, and soft robotics.

The advantage of producing artificial organs this way is that they can be made from a single piece of material,

and allow greater airflow than other artificial hearts made from metals and plastics. nstead of taking a bunch of nuts and bolts

so further research needs to be conducted before such an artificial heart could be used for its intended purpose.

Whilst the creation of a 3d printed artificial heart remains the ultimate goal for Shepherd and co,

to provide transplanted organs or future artificial organ implants with the necessary connections to the rest of the body,

Last month, researchers from Stanford university developed touch-sensitive artificial skin that not only detects pressure, but can transmit signals to nerve cells.

But I now see a clear path where we can take our artificial skin.''Attached to a robot hand, the skin was able to detect pressure over the same range as its human counterpart,

In a similar way, the artificial skin produces signal pulses that vary in intensity according to the pressure level s

#Artificial skin That Can Send Pressure sensation To Brain cell Stanford engineers have created a plastic"skin"that can detect how hard it is being pressed

The team then hooked this pressure-sensing mechanism to the second ply of their artificial skin,

Covering a large surface is important to making artificial skin practical and the PARC collaboration offered that prospect.

They translated the electronic pressure signals from the artificial skin into light pulses which activated the neurons,

proving that the artificial skin could generate a sensory output compatible with nerve cells. Optogenetics was used only as an experimental proof of concept,
