Abstract
An improved urinary catheter having a unique, low volume device by which to retain the catheter within the bladder, so that urine can be removed therefrom. The retaining device consumes less volume in the bladder than that which would ordinarily be consumed by a conventional Foley-style balloon, whereby both the frequency and severity of urinary bladder spasms, which are induced by pressure against the trigonal area of the bladder, can be reduced. What is more, the retaining device is advantageously adapted to provide little resistance, and thereby minimize any damage to the urinary tract, in the event that a patient should suddenly and forceably attempt to remove the catheter from his bladder.
