3D printed skullcap

An anonymous man in the U.S. received what was then the world’s largest 3D-printed skull implant a year ago. That record has just been broken. A 22-year-old Dutch woman has just received a transplant of her entire cranium in an operation that lasted an incredible 23 hours. (Video)

Pacemaker under tongue may stop snoring

snoring

The Hypoglossal Nerve Stimulation System, works by stimulating the nerve which controls the muscles of tongue.

Scientists have come up with a new pacemaker-style device which they claim when implanted underneath one’s tongue could help stop snoring. A team claims that the new implant, called the Hypoglossal Nerve Stimulation System, works by stimulating the nerve which controls the muscles of tongue, thus helping reduce the severity of sleep apnoea, a major cause of snoring.

Revolutionary eye operation could allow millions of middle-aged people to abandon their reading glasses

eye

A revolutionary new treatment, involving an operation to insert a plastic implant into the eye, could allow millions to abandon their spectacles.

Needing to wear reading glasses is one of the signs of reaching middle-age.

Rik Krohn displays the remote control unit he uses to turn on an experimental nerve stimulator to combat his sleep apnea.

Loud snoring may do more than irritate your spouse: It can signal sleep apnea , depriving you of enough zzzz’s to trigger a car crash, even a heart attack.

Eye Implant Developed That Allows Blind to See Shapes and Objects

retina-implant

An experimental retinal implant allowed a blind research subject to see well enough to distinguish between different kinds of fruit.

Scientists have developed an eye implant that allowed three blind patients to see shapes and objects within days of treatment in a trial and say the device could become routine for some kinds of blindness in five years.

First Implantable Artificial Kidney Could Work as Well as a Living Organ

artificial kidney

The artificial kidney will be the size of a coffee cup. Blood will be pumped through microscopic filters using the body’s own blood pressure.

An artificial kidney that would be implanted inside the body and work as well as a living organ is just around the corner, scientists have revealed.  U.S researchers have just unveiled the first prototype model of the device, that could eliminate the need for dialysis.

Subretinal Implant Successfully Tested On Humans, Makes Blind Narrowly See

retinaimplantdiagram 7689
How many scientists does it take to properly install a lightbulb? When that lightbulb is an implant that stimulates retinal photoreceptors to restore one’s sight, quite a few — even if they disagree whether said implant should be placed on top of the retina (requiring glasses to supply power and video feed) or underneath, using photocells to channel natural sunlight. Now, a German firm dubbed Retina Implant has scored a big win for the subretinal solution with a three-millimeter, 1,500 pixel microchip that gives patients a 12 degree field of view…

World’s Smallest Solar Sensor Could Run Forever

500x_tinysolarchip

A low-power, sensor system is 1,000 times smaller than comparable commercial counterparts.

A 9-cubic millimeter solar-powered sensor system developed at the University of Michigan is the smallest that can harvest energy from its surroundings to operate nearly perpetually.

The U-M system’s processor, solar cells, and battery are all contained in its tiny frame, which measures 2.5 by 3.5 by 1 millimeters. It is 1,000 times smaller than comparable commercial counterparts.

Implantable Cancer Vaccine First To Eliminate Tumors In Mice

implantbased

A polymer implant, 8.5 mm in diameter, is embedded with chemical signals that encourage immune cells to attack tumors.

A cancer vaccine carried into the body on a carefully engineered, fingernail-sized implant is the first to successfully eliminate tumors in mammals, scientists report this week in the journal Science Translational Medicine.

 Tattooing dates back to at least Neolithic times and has experienced a resurgence in popularity in many parts of the world in recent years. Advancements in tattoo pigments and the refinement of tattooing equipment has seen in improvement in the quality of tattoos being produced. Today it’s possible to get ink that glows under UV light, but a new technology could see tattoos that emit their own light. Researchers have been able to build thin, flexible silicon electronics on silk substrates that almost completely dissolve inside the body, paving the way for embedded LED tattoos that offer much more than just aesthetic appeal.The devices are made of a thin film of silk on which silicon transistors about one millimeter long and 250 nanometers thick are placed…
