Remembering Dr. Sven Seldinger

A severe attack of common sense in 1953


Dr. Sven Ivar Seldinger (1921-1998), the Swedish radiologist who invented the “Seldinger technique” for percutaneous entry into the vascular system, would have been 93 this April. The technique, which provided an alternative to many more invasive procedures, revolutionized medicine in many ways. We’re proud to honor Dr. Seldinger’s life and legacy.
