The da Vinci Xi offers improved access to the patient's body

While many people no doubt still look at Intuitive Surgical's da Vinci robotic surgical system as a sort of "wonder of the future," it's actually been around now for over 10 years. Therefore, it shouldn't come as a surprise that a new-and-improved model has just been announced. Among other things, the da Vinci Xi Surgical System promises a greater range of motion and more reach than its predecessor.  Read More

The business end of Medrobotics Corp's Flex System

When we last heard about the modular snake robot designed by Carnegie Mellon University robotics professor Howie Choset, it had been used to explore an abandoned nuclear power plant. Now, however, a new line of robots based on it are set to explore something a little more confined – the human body.  Read More

A woman's skull has been successfully replaced with a 3D-printed implant

A 22-year-old woman has had the whole top of her skull replaced with a customized 3D-printed implant. The patient had been suffering from severe symptoms as a result of a condition that causes a thickening of the skull. It is believed that the procedure was the first of its kind.  Read More

Built in three pieces using a flexible filament, the 3D-printed heart reportedly took arou...

3D printing technology has assisted in life-saving heart surgery performed on a 14-month old child, with engineers at the University of Louisville producing a printed model of the child's heart prior to the procedure that enabled doctors to better prepare for the operation.  Read More

The optical device uses a laser to determine how quickly a person's blood will clot  (Imag...

Not everyone's blood clots at the same rate. While that might seem like simply an interesting bit of trivia, it's anything but trivial to doctors performing operations or emergency procedures, who need to know what might be required in the way of transfusions or anticoagulant drugs. Now, an optical device can provide them with that information within minutes.  Read More

MD Julie Margenthaler wears the eyepiece during cancer surgery

When doctors are operating on a patient to remove a cancer, they face a major challenge: telling healthy and cancerous cells apart. But a new device being developed by researchers at Washington University in St. Louis' School of Medicine could provide a safe, affordable and portable solution.  Read More

The BioPen lets surgeons 'draw' live cells and growth factors directly onto the site of an...

Devices like the 3Doodler and SwissPen literally put 3D printing technology in the hands of consumers, but a new BioPen developed at the University of Wollongong in Australia is targeted at more skilled hands. The handheld device is designed to let surgeons "draw" live cells and growth factors directly onto the site of an injury to help accelerate the regeneration of functional bone and cartilage.  Read More

The capsule being tested using silicone gel

Researchers at Nashville's Vanderbilt University have developed a wireless capsule that can restore a sense of touch for surgeons. Keyhole surgeries or other minimally invasive procedures could benefit greatly from this new technology, as the capsule provides haptic feedback to help doctors maneuver and make important conclusions during surgery.  Read More

Performing surgery while wearing Google Glass could offer advantages for doctors and patie...

A surgeon at The Ohio State University recently performed a routine knee surgery wearing Google Glass. Streaming live video footage from the operating room, the demonstration showcased some of the ways in which Glass could be useful in the operating room.  Read More

The active cannula goes to work on a simulated blood clot

Intracerebral hemorrhaging is what occurs when a blood vessel in the brain bursts, and the blood which subsequently leaks out of that vessel forms a clot that places pressure on the surrounding brain tissue. It’s not that uncommon of an occurrence, it’s difficult to treat, and is fatal in about 40 percent of cases. Help may be on the way, however. A team from Nashville’s Vanderbilt University has created a robotic device that is designed to remove those clots, in a safe and minimally-invasive fashion.  Read More
