Peripherally inserted central catheter

A catheter left inside the body, either temporarily or permanently, may be referred to as an "indwelling catheter" (for example, a peripherally inserted central catheter).
It is a catheter that enters the body through the skin (percutaneously) at a peripheral site, extends to the superior vena cava (a central venous trunk), and stays in place (dwells within the veins) for days or weeks.

Urinary catheterization

urinary cathetercathetercatheterization
In urinary catheterization a latex, polyurethane, or silicone tube known as a urinary catheter is inserted into a patient's bladder via the urethra.

Peripheral venous catheter

intravenous catheterperipheral venous accesscannula
In medicine, a peripheral venous catheter (PVC), peripheral venous line or peripheral venous access catheter is a catheter (small, flexible tube) placed into a peripheral vein for venous access to administer intravenous therapy such as medication fluids.

Foley catheter

For example, silicone is used in Foley catheters where fractures have been reported, often requiring surgery to remove the tip left in the bladder.
Manufacturers usually produce Foley catheters using silicone or coated natural latex.

Suprapubic cystostomy

Cystostomysuprapubic catheterVesicostomy
Initially, a thin tube (catheter) is placed through the skin just above the pubic bone into the bladder, often with the assistance of ultrasound imaging.

Epidural administration

Epidural techniques frequently involve injection of drugs through a catheter placed into the epidural space.

Blood pressure

However, measurement of pressures in the venous system and the pulmonary vessels plays an important role in intensive care medicine but requires invasive measurement of pressure using a catheter.

Central venous catheter

A central venous catheter (CVC), also known as a central line, central venous line, or central venous access catheter, is a catheter placed into a large vein.


Using a system of guide wires and catheters, a type of contrast agent (which shows up by absorbing the X-rays), is added to the blood to make it visible on the X-ray images.

Intravenous therapy

A peripheral IV line (PVC or PIV) consists of a short catheter (a few centimeters long) inserted through the skin into a peripheral vein (any vein not situated in the chest or abdomen).

Pulmonary artery catheter

Pulmonary artery catheterization (PAC), or right heart catheterization, is the insertion of a catheter into a pulmonary artery.

Balloon sinuplasty

Balloon technology was initially cleared by the U.S. Food and Drug Administration in 2005 and is an endoscopic, catheter-based system for chronic sinusitis.


balloon angioplastyangioplastiespercutaneous transluminal angioplasty
Angioplasty requires an access vessel, typically the femoral or radial artery or femoral vein, to permit access to the vascular system for the wires and catheters used.


nephrostomy, percutaneousnephrostomiesPercutaneous nephrostomy
Nephrostomies are created by surgeons or interventional radiologists and typically consist of a catheter which pierces the skin and rests in the urinary tract.

Catheter ablation

cardiac ablationradiofrequency catheter ablationAblation
Catheter ablation involves advancing several flexible catheters into the patient's blood vessels, usually either in the femoral vein, internal jugular vein, or subclavian vein.

Umbilical line

Umbilical Venous CatheterUmbilical Arterial Catheterumbilical veins
Generally the UAC/UVC (Umbilical Artery Catheter/Umbilical Vein Catheter) is used in Neonatal Intensive Care Units (NICU) as it provides quick access to the central circulation of premature infants.

Seldinger technique

introducer sheath
An introducer sheath can be used to introduce catheters or other devices to perform endoluminal (inside the hollow organ) procedures, such as angioplasty.

Tracheal tube

He is also credited with the invention of the modern "disposable" plastic endotracheal tube now used routinely in surgery.
A tracheal tube is a catheter that is inserted into the trachea for the primary purpose of establishing and maintaining a patent airway and to ensure the adequate exchange of oxygen and carbon dioxide.

Intracranial pressure

A catheter can be surgically inserted into one of the brain's lateral ventricles and can be used to drain CSF (cerebrospinal fluid) in order to decrease ICP's.

Artificial insemination

Intrauterine insemination (IUI) involves injection of washed sperm into the uterus with a catheter.

Cardiac electrophysiology

The system is designed to visualise the real-time calculated position and orientation of a specialised RF ablation catheter within the patient's heart in order to minimise radiation exposure during fluoroscopy, increase the accuracy of targeted RF ablation and reacquisition of pacing sites for re-ablation.

In vitro fertilisation

Embryos are transferred to the patient's uterus through a thin, plastic catheter, which goes through her vagina and cervix.

Severe irritation takes place if a latex catheter is inserted in the urinary tract of a person allergic to latex.
