 silicone rubber, nylon, polyurethane, polyethylene terephthalate (PET),  latex, and thermoplastic elastomers.  Silicone is one of the most common choices because it is inert and unreactive to body fluids and a range of medical fluids with which it might come into contact.  On the other hand, the polymer is weak mechanically, and a number of serious fractures have occurred in catheters.  For example, silicone is used in Foley catheters where fractures have been reported, often requiring surgery to remove the tip left in the bladder.

Polyimides are used to manufacture vascular catheters for insertion into small vessels in the neck, head and brain.

There are many different types of catheters for bladder problems.  A typical modern intermittent catheter is made from polyurethane and comes in different lengths and sizes for men, women and children.  The most advanced catheters have a thin hydrophilic surface coating.  When immersed in water this coating swells to a smooth, slippery film making the catheter safer and more comfortable to insert.  Some catheters are packed in a sterile saline solution.

Interventional procedures

Different catheter tips can be used to guide the catheter into the target vessel.

Cardiac catheterization (cardiac cath or heart cath) is a procedure to examine how well your heart is working. A thin, hollow tube called a catheter is inserted into a large blood vessel that leads to your heart. A cardiac cath  provides information on how well your heart works, identifies problems and allows for procedures to open blocked arteries. The doctor will make a needle puncture through your skin and into a large blood vessel.  A small straw-sized tube (called a sheath) will be inserted into the vessel. The doctor will gently guide a catheter (a long, thin tube) into your vessel through the sheath. A video screen will show the position of the catheter as it is threaded through the major blood vessels and to the heart. You may feel some pressure in your groin, but you shouldn't feel any pain.
Various instruments may be placed at the tip of the catheter. They include instruments to measure the pressure of blood in each heart chamber and in blood vessels connected to the heart, view the interior of blood vessels, take blood samples from different parts of the heart, or remove a tissue sample (biopsy) from inside the heart.

The catheter used for hemodialysis is a tunneled catheter because it is placed under the skin. There are
silicone rubber, nylon, polyurethane, polyethylene terephthalate (PET),   latex, and thermoplastic elastomers.   Silicone is one of the most common option because it is inert and unreactive to soundbox fluids and a range of medical fluid with which it might come into contact.   On the early hand, the polymer is weak mechanically, and a number of dangerous fractures have occurred in catheter.   For example, silicone is used in Foley catheters where fractures have been report, often command surgery to remove the gratuity left in the bladder.

The doctor of the church will make a needle puncture through your skin and into a large blood vessel.   A minor straw - sized pipe (called a cocktail dress) will be inserted into the vessel. The doctor will gently lead a catheter (a long, slender tube) into your vessel through the cocktail dress. A video screen will show the position of the catheter as it is weave through the major blood vessels and to the heart. You may palpate some pressure in your groin, but you shouldn't palpate any pain. 
 Various instruments may be identify at the tip of the catheter.
