Artificial heart implanted in France

Artificial heart implanted in France

For the first time, a bioprosthetic heart that may give patients up to five years of extra life has been successfully implanted in a 75-year-old French man.

The procedure was performed on December 18th at France’s Georges Pompidou European Hospital, and the patient is said to be doing well.

The artificial heart, designed by French biomedical firm Carmat, is powered by Lithium-ion batteries that can be worn externally.

The heart that was put into the patient uses a range of “bio-materials”, including bovine tissue, to reduce the likelihood of the body rejecting it, ‘The Telegraph’ reported.

This device is intended to replace a real heart for as many as five years, unlike previous artificial hearts that were created mainly for temporary use.

Carmat’s artificial heart is three times heavier than an average healthy human heart.

The patient is currently awake in the intensive care unit and is speaking with family members.

“We are delighted with this first implant, although it is premature to draw conclusions given that a single implant has been performed and that we are in the early post-operative phase,” Marcello Conviti, the chief executive of Carmat, said.

The device mimics heart muscle contractions and contains sensors that adapt the blood flow to the patient’s moves, the report said.

The first bionic hand that allows an amputee to feel what they are touching will be transplanted later this year that could introduce a new generation of artificial limbs with sensory perception.

The wiring of his new bionic hand will be connected to the patient’s nervous system via electrodes clipped onto two of the arm’s main nerves, the median and the ulnar nerves.

With this the man will be able to control the movements of the hand as well as receiving touch signals from the hand’s skin sensors.

Heart can be turned ON and OFF by a light switch

Heart can be turned ON and OFF by a light switch

Millions of people around the world suffer from some degree of cardiac arrhythmia, wherein a person’s heart beats too slowly, too quickly or at irregular intervals. Such heart rhythm problems can cause a shortness of breath, fainting and, in worst-case scenarios, death.

The good news is devices like pacemakers and defibrillators allow doctors to introduce electrical signals to set patients’ hearts at regularly timed beats.

But these small mechanical devices come with risks.

Patients must undergo invasive surgical procedures to permanently implant the devices, which can cause cardiac tissue damage. There are other challenges too, such as lifestyle limitations and the occasional battery malfunction.

Oscar Abilez, a cardiovascular physician with a doctorate in bioengineering is working with a team of Stanford scientists to develop a novel biological pacemaker – one that controls the human heart with light.

Quick-thinking doctor uses mentor’s Whatsapp tips to save labourer’s hand

Quick-thinking doctor uses mentor’s Whatsapp tips to save labourer’s hand

Boisar doctor sends photos of the nearly-severed hand to his mentor, who then guides him through a complex 10-hour-long microsurgery.

 

Besides performing a microsurgery that could only be done in a super-speciality hospital, a Boisar-based orthopaedic surgeon used sheer presence of mind to save the nearly severed hand of a labourer after it was almost sliced off by a saw machine.

 

Since he had never handled such a case, Dr Jitendra Patil, who owns a hospital in Boisar, immediately called up his mentor. Dr Hemant Patankar, orthopaedic head of department at Ghatkopar’s Rajawadi Hospital, directed him on how to go about the delicate operation going by photographs and details of the wound that Dr Patil sent him via smartphone messenger WhatsApp.

On Tuesday, Lifeline Hospitals in Chennai live-streamed an upper gastro-intestinal laparoscopy procedure on a 45-year-old man and a hernia repair on a 42-year-old woman to medical students seated two blocks away using Google Glass.

“It felt like I was glancing at my rearview mirror while driving. I was focusing on the surgeries and talking to my students at the same time. At one point, I stopped feeling it was an external device,” said Dr J S Rajkumar, chief surgeon of the hospital.

Cancerous tumor sniffing intelligent knife designed

Cancerous tumor sniffing intelligent knife designed

An “intelligent” knife that can sniff out tumors to improve cancer surgery has been developed by scientists.

Removing cancerous tumors from a patient is a very precise science, and it can be very difficult for surgeons to determine where tumors begin and end.

The Imperial College London team hope to overcome the dangerous and common problem of leaving bits of the tumour in a patient, which can then regrow.

Pressure Ulcers prevented using mattress sensing MAP system

Pressure Ulcers prevented using mattress sensing MAP system

Wellsense of Nashville, Tennessee is a company that has developed a monitoring technology that helps prevent pressure ulcers in bed ridden patients in a clinical setting.

The MAP System involves a special electronic sheet placed over a mattress that has thousands of sensors that in real time detect the pressure distribution of the patient’s body over the bed.

Researchers Create Inner Ear from Stem Cells

Researchers Create Inner Ear from Stem Cells

Researchers have converted embryonic stem cells from mice into structures of the inner-ear. The breakthrough will help with cellular therapy and new drugs for inner-ear disorders.

Scientists from Indiana University have transformed mouse embryonic stem cells into key structures of the inner ear.

These are stem-cell-derived sensory hair cells (in red) with hair bundles (green). Cellular nuclei are shown in blue.
