Sven-Ivar Seldinger

Sven-Ivar Seldinger was a Swedish radiologist who developed a medical technique in the 1950s known as the Seldinger technique. This method involves using a thin needle to access blood vessels or other structures in the body. After inserting the needle, a guide wire is threaded through it, allowing doctors to place catheters or other devices with precision. The Seldinger technique is widely used in various medical procedures, such as angiography and catheter placement, and has significantly improved safety and effectiveness in minimally invasive surgeries. It remains a fundamental practice in modern medicine.
