William H. Dobelle facts for kids

Dr. Bill Dobelle (October 24, 1941 – October 5, 2004) was a biomedical researcher who developed experimental technologies that restored limited sight to blind patients, and also known for the impact he and his company had on the breathing pacemaker industry with the development of the only FDA approved device for phrenic nerve pacing. He was the former director of the Division of Artificial Organs at the Columbia-Presbyterian Medical Center.

Education

Dobelle was born in Pittsfield, Massachusetts, on October 24, 1941, to orthopedic surgeon Martin Dobelle and Lillian Mendelsohn Dobelle. His younger brother Evan Dobelle is a politician and educator.

With his father, Dobelle designed improvements for the artificial hip when he was 13. He started college at Vanderbilt the following year, though he soon dropped out to pursue other interests. In 1957, he won the South Florida Regional Regional Science fair with an X-ray machine he built the previous year; he then went on to win the National Science Fair with the device. He earned his bachelor's and master's degrees in biophysics at Johns Hopkins University, where he worked on the development of medical tests. He finished his Ph.D. in neurophysiology at the University of Utah.

Career and artificial vision

Dobelle was the CEO of the Dobelle Institute, headquartered in Lisbon, Portugal, which concentrates on artificial vision for the blind.

He was associate director of the Institute of Biological Engineering at the University of Utah from 1969–1975, and persuaded General Instrument to donate a microcircuit laboratory to the school. He later served as director of the Division of Artificial Organs at Columbia-Presbyterian Medical Center. He was a founding fellow of the American Institute for Medical and Biological Engineering. Throughout his career, he worked closely with friend and mentor Willem Johan Kolff, with whom he was nominated for the Nobel Prize in Physiology or Medicine in 2003.

In 1983, he bought Avery Laboratories (now Avery Biomedical Devices), where he worked on neurostimulation and the artificial eye. Dobelle led one of several teams of scientists around the world seeking to develop technology for artificial vision. Dobelle's teams developed a brain implant which films the visual field in front of the patient and transmits it to the brain's visual cortex, allowing the patient to see outlines. He received widespread publicity on January 17, 2000, when it was announced that a patient known as "Jerry," blind after a blow to his head 36 years previously, had regained his ability see thanks to the artificial eye Dobelle had spent over 30 years developing. Jerry "sees" by wearing spectacles attached to a miniature camera and an ultrasonic rangefinder. They feed signals to a computer worn on the waistband, which processes the video and distance data, which is then sent by another computer to 68 platinum electrodes implanted in Jerry's brain, on the surface of the visual cortex. He sees a simple display of dots that outline an object. Jerry's vision is the same as a severely shortsighted person—equivalent to 20/400. He is able to read two-inch letters at five feet.

The Dobelle Eye has been tested in several people, allowing individuals who were once completely blind to see the outlines of images in the form of white dots on a black background. In 2002, 38-year-old Jens Naumann, a blind man, was able to use the device to drive a car in the parking lot of the Dobelle Institute. His story was documented in the film Blind Hope. Cheri Robertson, a 41-year-old woman who was also implanted with the system, was profiled in the documentary "Robochick and the Bionic Boy" in 2008.

Portable breathing pacemaker

Dobelle's Avery Biomedical Devices also created the portable breathing pacemaker, which has been used by patients with quadriplegia, central apnea, and other respiratory ailments.

There are a few groups who continue to experiment with cortical vision implants [51] but no system like Dobelle's is presently available" (40).
