Claim 0:
1. A urinary catheter device for obstetrical patients that will allow drainage of urine from a bladder without causing interference or obstruction to a descending fetal head during a labor process, the urinary catheter device comprising:
a catheter body insertable into a urethra comprising:
a centrally located urine passage with a central cavity open on both ends to allow the drainage of urine;
a spherical balloon inflation channel with a central cavity and an inflatable spherical balloon on an indwelling end of the spherical balloon inflation channel and a check valve on an external end of the spherical balloon inflation channel, the check valve preventing inadvertent deflation of the spherical balloon;
a retaining balloon inflation channel separate from the spherical balloon inflation channel, the retaining balloon inflation channel having a central cavity and a non-spherical flat low-profile-retaining balloon on an indwelling end of the retaining balloon inflation channel, the retaining balloon surrounding a perimeter of the catheter body and being smaller than the spherical balloon, and a check valve on an external end of the retaining balloon inflation channel;
the spherical balloon positioned closer to an indwelling end of the urine passage than the retaining balloon is;
wherein the catheter body further comprises an outer layer that incorporates the centrally located urine passage, spherical balloon inflation channel and retaining balloon inflation channel into one single and functional unit.
