This collectible antique medical instrument is from American Cystoscope Makers and it was produced for Brown-Buerger Cystoscope. It appears to be complete - Please see the photos for more detail. There are tips, grease and bulbs in the small storage area under the "American Cystoscope Makers" label (it slides back) which are not photographed. All parts and tools are within the Walnut Case. This was came as part of a complete OB / GYN office from the 1930's - 40's that we recently acquired.
The case measures about fourteen and five-eighths inches by six and three-quarters inches by two and one-quarter inches.
This instrument was patented in 1909, and I suspect this instrument may have been manufactured before the end of the 1920s. It was developed by Dr. Leo Buerger in collaboration with Dr. F. Tilder Brown.
Dr. Buerger was born in Vienna, but raised in the the US. He studied at Columbia University and later was a resident at Breslau Surgical Clinic in Germany. Returning to the US in 1905, he had a teaching relationship at Mount Sinai Hospital, specializing in urological surgery. Buerger's disease, a chronic inflammatory disease of the peripheral vessels forming blod clots resulting in reduced blood flow, with consequential ulceration and gangrene is named for him.
Dr. Brown was the silent partner and did not seem to cut such a wide swath. Buerger was said to have campaigned to have this instrument renamed "Buerger's cystoscope." He described it as an instrument for direct irrigation and double catheterization. For many years it was the standard tool of urologists.
This instrument is in a custom-fitted walnut case. On the interior of the top of the case is a plate that identifies the contents as a "BROWN-BUERGER CYSTOSCOPE" with operator maintenance instructions imprinted on it. It also identifies "AMERICAN CYSTOSCOPE MAKERS, INC., NEW YORK, U. S. A." as the manufacturers. It identifies "49L" as the appropriate lamp to use in the instrument.
