Tunneled Catheter Insertion Tunneled catheter insertion is a procedure to insert a thin‚ flexible tube (catheter) into a vein. The catheter makes it easier to draw blood‚ give blood products‚ remove waste products from the blood (hemodialysis)‚ and give medicines. This procedure is usually done when the bloodstream needs to be accessed many times over a long period of time. Tunneled catheters can be placed in different parts of the body depending on how they will be used. The most common place
