In medicine, a catheter (/ ˈ k æ θ ə t ə r / [1] KA-thə-tər) is a thin tube made from medical grade materials serving a broad range of functions. Catheters are medical devices that can be inserted in the body to treat diseases or perform a surgical procedure.
Common indications for urinary catheterization include acute or chronic urinary retention (which can damage the kidneys) from conditions such as benign prostatic hyperplasia, orthopedic procedures that may limit a patient's movement, the need for accurate monitoring of input and output (such as in an ICU), urinary incontinence that may compromise the ability to heal wounds, and the effects of ...
In some individuals, long-term permanent scarring and strictures of the urethra occur. [14] Defective catheters may be supplied, which break in situ. The most common fractures occur near the distal end or at the balloon. Catheters can be pulled out by patients while the balloon is still inflated, leading to major complications or even death.
For short-term CVC sites, dressings must be changed at least every 7 days for transparent dressings, and every 2 days for gauze dressings. For long-term implanted or tunneled catheters, dressings are to be changed no more than once weekly unless soiled or loose. Routine removal and replacement of a central venous catheter is not recommended.
A port catheter is passed through the tunnel where one end is attached to the chemport and another end is left hanging out near the IJV insertion site. The length of the hanging port catheter should be about 16 to 17 cm (or can be measured from the IJV insertion site until 2 cm below the sternal angle where the right atrium should begin).
A peripherally inserted central catheter (PICC or PICC line), also called a percutaneous indwelling central catheter or longline, [1] is a form of intravenous access that can be used for a prolonged period of time (e.g., for long chemotherapy regimens, extended antibiotic therapy, or total parenteral nutrition) or for administration of substances that should not be done peripherally (e.g ...

Catheters are medical devices that can be inserted in the body to treat diseases or perform a surgical procedure. By modifying the material or adjusting the way catheters are manufactured, it is possible to tailor catheters for cardiovascular, urological, gastrointestinal, neurovascular, and ophthalmic applications.
