Abstract: A urinary catheter assembly is disclosed having a catheter, a sheath enclosing an insertable portion of the catheter, and one or more vents in fluid communication with the lumen of the sheath and an environment outside the sheath.

Abstract: An indwelling urinary catheter assembly is disclosed having an indwelling catheter and a sheath enclosing an insertable portion of the indwelling catheter.

Abstract: A urinary catheter assembly is disclosed that comprises a catheter and pliable sheath, which protects at least part of the urethra-insertable portion of the catheter without enclosing the urine outlet of the catheter. In certain embodiments a free end of the catheter is made available to facilitate manipulation of the outlet for collection of a urine specimen. The sheath is attached to the catheter so as to prevent urine from entering the sheath and contaminating the catheter. A catheterization kit containing the catheter assembly is also disclosed, in which several items of equipment from a conventional catheterization kit are obviated, allowing for decreased nursing catheterization time and reduction of risk of urinary tract infection in the patient.

Abstract: A disposable hydrophilic catheterization device for inserting a hydrophilic catheter into the urethra of an individual for the purpose of evacuating the bladder is disclosed. The catheter device includes a catheter introducer, a flexible hydrophilic catheter and a flexible thin-walled sheath. The sheath surrounds the urethra-insertable portion of the catheter, is adapted for containing a wetting liquid, and prevents pooling of the wetting liquid with collected urine. A leak-resistant diaphragm disposed within the catheter introducer is capable of being pierced by the catheter tip to form a leak-resistant orifice around the wetted hydrophilic catheter as it moves through the orifice.
