Medical Eponyms
Foley catheter (1929)

In 1929 Foley first described a self-retaining balloon catheter (haemostatic bag catheter). The purpose of the device was to provide simultaneous urethral catheter drainage of the bladder and hemostasis following transurethral resection of the prostate.

During the 1930’s, Foley further developed his design in an attempt to provide continuous drainage of the bladder. The Foley his catheter concept included an inflatable balloon towards the tip of the tube which when inflated within the bladder maintained the catheter in place without external taping or strapping.

The finally perfected catheter was exhibited by American Anode, Inc., at the American Medical Association meeting at Atlantic City, June 14, 1935 and later the same month before the American Urological Association at San Francisco.

Following his presentation to the Foley took no steps to protect their innovation. On June 9, 1936, a patent describing a method for catheter production identical to Foley was awarded to Paul A. Raiche, of the Davol Rubber Company. In October 1936, Foley applied for the patent, and was awarded this after appearing before the patent office Board of Appeals. Raiche appealed this decision, which was overturned and the patent stayed with Raiche. Despite the patent ownership, the C. R. Bard Company of New Jersey commenced manufacture and distribution of the ‘Foley catheter’

Interesting Facts

Foley initially had a keen interest in the developing field of neurosurgery, being a protégé of the famous Dr. Harvey William Cushing and even going as far as to author and present four papers in the field of neurosurgery detailing the use of. Cushing was equally impressed with his pupil’s work, and offered to let him stay on as a permanent assistant. However, Cushing could only offer Foley a meagre $250 a month for his services which Foley, who was married with two daughters to support, was forced to decline. Foley subsequently decided to abandon the field of neurosurgery and instead pursue a career in urology.

There is also a popular rumour that Foley’s time with Cushing is what lead him to land his first job as a urologist. It is said that when Foley approached Dr. Arthur B. Ancker, the hospital administrator at Ancker Hospital, Ancker, who was rather deaf at the time, misheard Foley’s request for an appointment as a ‘urologist’ with one as a ‘neurologist’ and hired him solely based on his previous association with Cushing.
