In 1945, Edward Boyce Tuohy used Huber’s needle design for placement of spinal catheters. Although Huber patented the needle he did not publish any papers demonstrating its use.

In 1946, Huber applied for a patent on a needle with a ‘transversely curved wall…end portion’. Huber made many of his inventions available to the US Army during the war, including the Huber point which was adopted by the Army in 1942 and it is possible that Tuohy first encountered the Huber point during his time in the US Army.
