A small, flexible tube that may be inserted into various parts of the body to inject or remove liquids.
A piece of plastic or rubber tubing that is inserted into a vein or other hollow structure.
A tube passed into the body along one of the passages in the body.
A hollow, flexible tube that can be inserted into the body, through a blood vessel or natural body opening, to withdraw or remove fluid and sometimes to aid in diagnosis of a disorder. Using a technique called clean, intermittent catheterization, some children, such as those with spina bifida, learn at a very early age to insert a catheter into themselves to drain urine from their bladder, to prevent kidney damage or infection.
Flexible, usually rubber or soft plastic, tube inserted into the body for removing or instilling fluids for diagnosis or treatment purposes. In its most common use a catheter is inserted through the urethra into the bladder to withdraw urine and empty (e.g., before surgery) or irrigate the bladder.
A flexible, hollow tube inserted into various body cavities. Catheters are commonly used to empty the bladder through the urethra or to enter the heart through a vein in the arm or leg for examination. Catheters are also used in peritoneal dialysis for treatment of kidney failure.
A tube for insertion into a narrow opening so that fluids may be introduced or removed. Urinary catheters are passed into the bladder through the urethra to allow drainage of urine in certain disorders and to empty the bladder before abdominal operations.
A thin tube to be inserted into the body, via a natural opening or an incision into a blood vessel or other structure, for the purpose of putting something into the body or taking something out. For example, radiopaque drugs used in x-ray examinations may be introduced, or blood or urine may be removed by catheter.
Hollow tubes, usually made of rubber or plastic, used for passing into various organs of the body, either for investigational purposes or to give some form of treatment. They are used under strict sterile conditions.
A tube passed into the body for evacuating fluids or injecting them into body cavities. It may be made of elastic, elastic web, rubber, glass, metal, or plastic.
A flexible tube used to deliver fluids into or withdraw fluids from the body.
A hollow, flexible tube, made of plastic or rubber, which can be inserted through the urinary opening into the bladder to drain excess urine that cannot be excreted normally.
A hollow and pliable tube that is inserted into a body cavity, duct, or vessel to facilitate the passage of fluids.
A pliable tube designed for insertion into the body to facilitate the drainage or administration of fluids, as well as perform various other functions, is known as a catheter. One common application of catheters is to remove urine from the bladder. Additionally, catheters are utilized in procedures such as cardiac catheterization to assess the condition of the heart, in the dilation of obstructed blood vessels, and in the management of bleeding.
A flexible tube, typically made of rubber or elastic material, is inserted into a bodily canal or opening to facilitate drainage. The most common example is a tube placed through the urethra to help drain urine from the bladder when there’s a urinary obstruction.
