Based on new research, which included mostly children with ? rather than less severe autistic spectrum disorders ? the newly identified genetic variants for autism could represent about 15 percent of diagnoses of autism, estimates H?konarson. Having the variant does not automatically mean a person will develop autism, says that other genetic and environmental factors are considered to come into play, although the estimate of 15 percent is important, he said.
Abiomed, the device manufacturer, said that five to 10 medical centers will be trained to implant the AbioCor device.
?The vast majority of these patients are bedridden, extremely short of breath, and connected to multiple drugs intravenously.
The approval of ?humanitarian? is not full approval. It applies only to what Bram Zuckerman, MD, director of FDA?s device center, called the ?most serious of the sick.?
The approval is for the humane treatment of conditions that affect fewer than 4,000 patients a year in the United States, according to a statement of the FDA news. Like the short survival times suggest, the device remains experimental.
People who receive the device will be included in a post-approval study. The results of this study will be used to develop the next generation of artificial hearts.
In clinical studies, the extension part of the lives of patients in just four and a half months on average. One patient survived 17 months, another 10 months. Only one patient was able to return home.
A roll of transfer of power through the skin that feeds the system and recharges the internal battery from outside.
?The reason this is so exciting is that one day we?re talking about an innovative device that can save lives,? Schultz said in a press conference. ?The approval of the humanitarian program to use, is part of our way to ensure that this technology will be available to patients for whom waiting for full approval is not an option.?
?It ?important to recognize that this time the device is a niche targeted for a very sick heart failure population,? says Zuckerman.
?For many of these patients in the clinical study, only the ability to walk, to communicate clearly with their families to take trips outside the hospital, and to celebrate important family events, were ? in the eyes of patients and their families ? considered an improvement ?says Zuckerman.
However, the announcement represents an important step on the road to a fully functioning artificial heart, said Daniel Schultz, MD, director of FDA?s Center for Devices and Radiological Health.
