  • Patent number: 6090075
    Abstract: A disposable self-lubricating catheterization assembly for inserting a catheter into the urethra of an individual for the purpose of evacuating the bladder is disclosed. The catheter assembly includes a substantially rigid catheter introducer member for positioning the introducer against the urethral opening, a flexible catheter and a flexible thin-walled sheath surrounding the catheter and partially covering the catheter introducer. The catheter introducer comprises a reservoir portion, a guide portion, lubricant and a membrane. The lubricant essentially fills the reservoir and is prevented by the membrane from prematurely coating the catheter, in order to facilitate grasping of the catheter and feeding of the tube along the urethra and into the bladder. A catheterization assembly in accordance with the present invention is suitable for use for self-catheterization in the home or in a public restroom, and deters contamination and subsequent infection of the urinary tract.
