Dr. John Bentson, Who Invented a Better Brain-Imaging Tool, Dies at 83

It is part of a series about people who died in the obesity coronovirus epidemic. Read about others Here.

In the early 1970s, the field of neuroscience was still in its formative years, and among its earliest physicians were UCLA Medical Center in Los Angeles, Dr. John was Bentson. As he helped patients with the help of new technology such as CT scans and computer imaging, he saw an opportunity for innovation.

A sub-specialty of radiology, Neuroscience This includes diagnosis and treatment of diseases in the brain, spinal cord and nerves. A tool used in The treatment is a combination of an angiographic guidewire and a catheter, essentially a tapered wire and tube; Inserted through the foot, it may aid with clinical brain imaging and injection of contrast dye for the treatment of aneurysms. However, at this time, the guidelines were stricter, and at worst, could injure a blood vessel. Mr. Bentson decided to design a better type.

He envisioned a more gentle guide, which also had a flexible tip, and after UCLA created an initial prototype for him, other neuroradiologists began using his model. Cook Medical started manufacturing the device in 1973 and is still in use today, commonly known as the Bentson GuideWire.

Mr bentson Died On December 28, in a hospital in Los Angeles. He was 83. The reason for this was the complications of Kovid-19, his daughter Drs. Erica Drajan said.

“He liked to push the boundaries if he thought he could help the patient,” he said. “He liked to say that the utensils of the body are like a tree and he can feel that where he can feel them.”

Thousands of patients have benefited from his innovation, The American Society of Neuroradology Said after his death.

John Reinert Bentson was born on 15 May 1937 in Viroqua, Wis. To Carl and Stella (Hagen) Bentson, who were of Norwegian heritage. He was raised on his family’s dairy farm and as a boy he traveled to school during the winter on a wooden ski. His mother prepared Norwegian fare like a lutefisk.

A grandfather encouraged him to leave the farm and pursue higher education. Mr. Bentson graduated from the University of Wisconsin-Madison with a BS in Chemistry in 1957 and received his M.D. Medical school In 1961.

He traveled to the Peruvian rain forests in 1965 as a medic in a missionary team, and a tribe worked with him and taught him how to hunt with a spear. He served as a radiologist in the US Army in South Korea and in his spare time discovered the country on a motorcycle. She married Sheridan Murphy in 1969.

That year, Mr. Bentson joined UCLA Medical Center, and in 1971 he became head of its neuroradiology department. He held the position for three decades until he stepped down in 2002, but continued to work at the hospital before retiring in 2014.

In addition to his daughter, who is a pediatrician, he is survived by his wife; Another daughter, Christa; One son, Derek; And six grandchildren.

Mr. Bentson did not trademark the instrument under his name and never made much profit. However, he had no regrets about his daughter and was happy to learn that his device continued to help people. A few years ago, she went to someone working for Cook Medical.

“My dad invented the guide wire you sell,” she said.

“Your father is John Bentson?” He replied.

The company soon sent a surprise package to Mr. Bentson: a glass display that also contained an inscription with a coiled Bentson guide, thanking him for his contribution to neuroradiology. Mr. Bentson hung the plaque on his wall.
