Hemodialysis, also called dialysis, is the most common treatment for kidney failure. A dialysis machine is an artificial kidney which cleanses the blood. During dialysis, blood is drawn from the patient into the dialysis machine, circulated through the machine, and then returned to the patient. Two needles are inserted into the patient's bloodstream to allow this process to occur. Hemodialysis is normally performed three times a week and the purpose of vascular access is to provide reliable sites where the bloodstream can be easily accessed each time. There are three major types of vascular access: arteriovenous fistula, arteriovenous graft, and venous catheter. The great majority of vascular accesses are created in the arm, but they can also be created in the leg.

Hepatitis A is a highly contagious liver infection caused by the hepatitis A virus. The virus is one of several types of hepatitis viruses that cause inflammation and affect your liver's ability to function. You're most likely to contract hepatitis A from contaminated food or water or from close contact with someone who's infected. Mild cases of hepatitis A don't require treatment, and most people who are infected recover completely with no permanent liver damage. Practicing good hygiene, including washing hands frequently, is one of the best ways to protect against hepatitis A. Vaccines are available for people most at risk.

An unnamed Russian scientist has introduced the concept of a device that attaches to the wall of the artery. It would first stop blood flow to the area to prevent breakaway plaque. A drill would then scrape the plaque from the artery wall. The procedure of treating plaque buildup could include bypass surgery, stent replacement and balloon angioplasty. Since the plaques are of different types and locations in the body, the inventor proposed using different types of cutting mills.
