CATHETER-STYLET ASSEMBLYFOR SLIPOVER URETHRAL INSTRUMENTSAbstract of The DisclosureAn elongated, hollow filiform having atapered insertion tip is passed through the urethrato the urinary bladder and functions both as a probeto seek the lumen or opening of the urethra and as aguide so that a rigid, hollow stylet within a Councillcatheter or the like can be slidably passed over thefiliform into the bladder while the filiform remainsin a stationary position within the urethra and thebladder. The stylet and the filiform can then be re-moved to leave the catheter within the bladder. Ifthe urethra is constricted, a first elongated, hollowdilator can be guided over the filiform to dilate orwiden the urethra before the stylet and catheter areintroduced. If necessary, the first dilator can bereplaced by a second dilator having a larger outerdiameter to further dilate the urethra so that thediameter of the urethra will accommodate the Councillcatheter containing the hollow rigid stylet.
