Johns Hopkins University graduate students have invented a device to reduce the risk of infection, clotting and narrowing of the blood vessels in patients who need blood-cleansing dialysis because of kidney failure.

The device, designed to be implanted under the skin in a patient’s leg, would give a technician easy access to the patient’s bloodstream and could be easily opened and closed at the beginning and end of a dialysis procedure, according to the students. The prototype has not yet been used in human patients, but testing in animals has begun.
