Catheters are medical devices designed to be inserted into the body to provide access to various parts of the body for diagnostic or therapeutic purposes. These thin, flexible tubes are primarily made of materials like latex, silicone, or polyurethane, that ensure biocompatibility with the human body.
Catheters are used in a wide range of medical procedures, including but not limited to cardiovascular interventions, urinary catheterizations, neurosurgical procedures, and administering medication or fluids. They can be placed into blood vessels, urinary tract, gastrointestinal system, or other body cavities, depending on the specific medical need.
Typically, catheters are inserted into the body by medical professionals using a variety of techniques, such as percutaneous insertion, surgical methods, or minimally invasive procedures. Once inserted, they remain in place temporarily or permanently, depending on the purpose. Different types of catheters exist, including indwelling/retention catheters, urethral catheters, central venous catheters, and Foley catheters, among others.
Catheters often feature additional components, such as inflatable balloons, drainage or irrigation systems, and multiple lumens, enabling various functionalities. The selection of a specific catheter depends on the medical condition, patient's anatomy, and the desired outcome of the procedure.
It is imperative that catheters be maintained and used with utmost care, as improper use can lead to complications like infections, blockages, or tissue damage. Regular monitoring, sterile techniques during insertion and maintenance, and appropriate protocols for catheter removal are essential to minimize potential risks and ensure patient safety. Overall, catheters play a vital role in modern medicine by enabling precise access to specific body areas and facilitating various medical interventions.
